IDS and IPS: Understanding Similarities and Differences

IDS and IPS are crucial network security technologies often confused or used interchangeably. So, what’s the difference between IDS and IPS, and which one is the best choice for your organizational needs?

What Is IDS (Intrusion Detection System)?

An intrusion detection system (IDS) is a cybersecurity solution that monitors network traffic and events for suspicious behavior. IDS security systems aim to detect intrusions and security breaches so that organizations can swiftly respond to potential threats.

The types of IDS include:

• Network-based: A network-based IDS (NIDS) is deployed at strategic points within a computer network, examining incoming and outgoing traffic. It focuses on monitoring network protocols, traffic patterns, and packet headers.
• Host-based: A host-based IDS (HIDS) is installed on individual machines or servers within an IT environment. It focuses on monitoring system logs and files to detect events such as unauthorized access attempts and abnormal changes to the system.
• Hybrid: A hybrid IDS combines both network-based and host-based approaches. This type of IDS provides a more complete view of events within the IT ecosystem.

IDS tools work by analyzing network packets and comparing them with known attack signatures or behavioral patterns. If the IDS believes that it has identified an intruder, it sends an alert to system administrators or security teams. These alerts contain detailed information about the detected activity, letting employees quickly investigate and react. IDS plays a vital role in maintaining the security and integrity of computer networks and systems.

The benefits of IDS include:

• Early threat detection: IDS tools can proactively defend against cyberattacks by detecting potential threats at an early stage of the intrusion.
• Greater visibility: IDS solutions enhance organizations’ visibility into their IT environment, helping security teams respond to attacks more quickly and effectively.

The limitations of IDS include:

• False positives and false negatives: IDS tools aren’t perfect; they can generate both false positives (labeling benign events as threats) and false negatives (failing to detect real threats).
• Inability to prevent attacks: IDS solutions can detect attacks once they occur, but they are unable to prevent them from occurring in the first place.

What Is IPS (Intrusion Prevention System)?

What is IPS in networking, and how does it differ from IDS? An intrusion prevention system (IPS) is a cybersecurity solution that builds on the capabilities of IDS. IPS cyber security tools cannot only detect potential intrusions but also actively prevent and mitigate them.

As with IDS, the types of IPS include:

• Network-based: A network-based IPS (NIPS) is deployed at strategic points within a computer network, often at network gateways. It can protect the organization’s entire network, including multiple connected hosts and devices.
• Host-based: A host-based IPS (HIPS) is deployed on a specific machine or server, offering protection to a single host. It monitors system activities and can take actions to block or limit access to system resources.
• Hybrid: A hybrid IPS combines both network-based and host-based approaches. For example, a hybrid IPS may be primarily network-based but also include features for protecting individual hosts.

The benefits of IPS include:

• Real-time threat prevention: IPS can block or mitigate identified threats in real time, providing 24/7 automated protection for IT environments.
• Enhanced network defense: Unlike IDS tools, IPS systems are able not only to detect threats but take action to defend against them by blocking malicious and suspicious traffic.

The limitations of IPS include:

• Performance impact: IPS tools must examine all incoming and outgoing traffic, which can introduce latency and slow down network performance.
• Frequent updates: For maximum effectiveness, IPS solutions need to be regularly updated with the latest information about threat signatures, which can require significant time investment and expertise.

Differences Between IDS and IPS

Now that we’ve discussed IDS and IPS definitions, what can we say about IDS vs. IPS?

The main difference between IDS and IPS is that while IDS tools are only capable of detecting intrusions, IPS tools can actively prevent them as well. This basic distinction has several important repercussions for the question of IDS vs. IPS:

• Functionality: IDS tools are restricted to detecting threats, while IPS tools can both detect and prevent them.
• Response: IDS tools send alerts when a threat is detected, while IPS tools can automatically block threats based on predefined security policies or rules.
• Workflow: IDS tools passively monitor data flow, while IPS tools actively inspect network packets and take action to prevent or mitigate threats.

Advances in IDS/IPS Technology

IDS/IPS technology has significantly evolved since it was introduced. Some developments in IDS/IPS solutions include:

• Machine learning and AI: IDS/IPS tools can use machine learning and artificial intelligence to enhance their detection capabilities, learning from historical data about cyber threats.
• Behavioral analysis: IDS/IPS tools can use a technique known as behavioral analysis: comparing network traffic or user behavior to a baseline that helps identify anomalies or deviations.
• Cloud-based deployments: With the increasing adoption of cloud computing, many IDS/IPS tools can now be deployed in cloud-based IT environments to make them more flexible and scalable.

IDS/IPS and Regulatory Compliance

Installing IDS and IPS tools may be necessary for organizations to meet regulatory compliance requirements. The use cases of IDS and IPS for regulatory compliance include:

• Threat detection and incident response: IDS and IPS solutions actively monitor network traffic, system logs, and events to detect and defend against security threats.
• Protecting sensitive data: By blocking unauthorized access to confidential information, IDS and IPS are invaluable tools for complying with data privacy standards.
• Logging and reporting: IDS and IPS solutions generate system logs and provide reporting capabilities that companies can use in the event of an external audit.

Many data privacy and security regulations explicitly or implicitly require organizations to implement IDS and IPS tools. For example, PCI DSS is a security standard for businesses that handle payment card information. According to PCI DSS Requirement 11.4, companies must “use network intrusion detection and/or intrusion prevention techniques to detect and/or prevent intrusions into the network.”

The GDPR (General Data Protection Regulation) is another regulation that may require IDS/IPS solutions. The GDPR is a law in the European Union that safeguards the privacy of citizens’ personal data. According to the GDPR, businesses must take “appropriate technical and organizational measures” to protect this data against breaches and unauthorized access, which could include deploying an IDS/IPS.

Misconceptions About IDS/IPS

Despite the widespread use of IDS and IPS solutions, there are some common misconceptions such as:

• Total prevention: IDS and IPS tools cannot offer 100 percent protection against a cyber attacks. They can only detect suspicious activity based on predefined rules and signatures, which limits them to known attack patterns.
• No other defenses required: IDS and IPS solutions can be highly effective, but they are only one piece of the cybersecurity puzzle, along with tools such as firewalls and antimalware software.
• Only useful for large enterprises: IDS/IPS technology is effective for businesses of all sizes and industries, from tiny startups to huge multinational firms.

How to Identify Network Security Threats and Vulnerabilities

Anyone who operates a computer network is susceptible to security threats and vulnerabilities. Hackers, criminals, and other malicious actors often exploit these weaknesses to steal data or disrupt service. To protect your network from these threats, it is important to be able to identify them and take appropriate steps to mitigate risks. Here we will provide an overview of some of the most common security threats and vulnerabilities as well as tips on how to detect them.

What Is a Network Threat?

A network threat is when an attacker targets a computer network or the computers and devices connected to it. Network threats can cause significant damage to data, systems, and networks and lead to downtime or even complete system failure. There are many different types of network threats, but some of the most common include:

◉ Denial-of-Service (DoS) Attacks: A DoS attack is an attempt to make a computer or network resource unavailable to users. They can be carried out using various methods, including flooding the target with requests or traffic or exploiting vulnerabilities in the network or system.

◉ Distributed Denial-of-Service (DDoS) Attacks: A DDoS attack is similar to a DoS attack, but multiple computers or devices, known as zombies, are used to carry out the attack. A large number of requests or traffic from the zombies can overwhelm the target, thus denying access to legitimate users. 

◉ Malware: Malware or malicious software refers to any type of software that is designed to damage or disrupt a computer system. Viruses, worms, and Trojans are some examples of malware.

◉ Phishing: Phishing is a type of social engineering attack that attempts to trick users into revealing sensitive information, like passwords or credit card numbers. Such attacks are often carried out by email and may include links to fake websites that look identical to the real website (SecurityScorecard, 2021). 

What Are Network Vulnerabilities?

Network vulnerabilities are weaknesses in a computer network that malicious actors can exploit to gain unauthorized access, launch DoS attacks, or spread malware. While some vulnerabilities are unintentionally introduced during the design and implementation of a network, others may be deliberately introduced by attackers.

Common types of network vulnerabilities include unpatched software flaws, weak passwords, and open ports. To protect a network from attack, it is important to regularly scan for vulnerabilities and take steps to remediate them. Network administrators can use a variety of tools to perform vulnerability scans, including open source and commercial products.

Once a vulnerability has been identified, it is essential to fix the loophole based on the potential impact of an exploit. For example, a vulnerability that could allow an attacker to gain administrative access to a server should be addressed urgently. In contrast, a less critical vulnerability may be patched at a later time.

Network vulnerabilities can have a wide range of impacts, from causing minor disruptions to leading to complete system compromise. In some cases, attackers may exploit vulnerabilities to launch DoS attacks or steal sensitive data. In other cases, they may use vulnerabilities to gain control of systems and use them for malicious purposes such as sending spam or launching attacks against other targets.

What Are the Types of Network Security Threats?

While there are many different types of network security threats out there, some of the most dangerous ones include:

◉ Viruses and Malware: Viruses and malware are malicious software programs that can infect your computer or network and cause serious damage. They can delete important files, steal confidential information, or even shut down your entire system.

◉ SQL Injection Attacks: SQL injection attacks exploit vulnerabilities in web applications that use Structured Query Language (SQL) to communicate with databases. By injecting malicious SQL code into these vulnerable applications, attackers can gain access to sensitive data or even take control of the entire database.

◉ OnPath Attacks: OnPath attacks occur when an attacker intercepts communication between two parties and impersonates each party to the other. This allows the attacker to eavesdrop on the conversation or modify the data being exchanged.

◉ Password Attacks: Password attacks are common types of network attacks because they are very effective. There are many types of password attacks, but some of the most common include brute force attacks, dictionary attacks, and rainbow table attacks (EasyDmarc, 2022).

What Are the Main Types of Security Vulnerability?

In computer security, a vulnerability is a weakness that can be exploited by a threat actor, usually for malicious purposes. Vulnerabilities can be found in many different areas of a system, including hardware, software, networks, and even people.

There are four main types of security vulnerabilities:

◉ Misconfigurations: Incorrectly configured systems and applications are often the weakest links in an organization’s security posture. A poorly configured firewall in cybersecurity, weak passwords, and leaving default accounts active are all examples of common misconfigurations that can lead to serious security vulnerabilities.

◉ Unsecured APIs: Many modern applications rely on application programming interfaces (APIs) to function properly. However, if APIs are not properly secured, they can be a serious security vulnerability. Attackers can exploit unsecured APIs to gain access to sensitive data or even take control of entire systems.

◉ Outdated or Unpatched Software: Software vulnerabilities are often the root cause of major security breaches. Outdated software is especially vulnerable, as attackers can exploit known weaknesses that have already been patched in newer versions. Unpatched software is also a major security risk, as many organizations fail to apply critical security updates in a timely manner.

◉ Zero-Day Vulnerabilities: A zero-day vulnerability is a previously unknown security flaw exploited by attackers before the vendor has patched it. These types of vulnerabilities are extremely dangerous, as there is usually no way to defend against them until after they have been exploited (CrowdStrike, 2022).

So, what can you do to address these types of security vulnerabilities?

The Ultimate Guide to Wireless Network Security for Small Businesses

Wireless networks have become an integral part of our lives in the digital age. We use them to stay connected with family and friends, conduct business, and access the internet. A wireless network allows devices to connect to the internet without being physically connected to a router or modem. While this convenience can be a lifesaver when you need to get work done on the go, it can also leave your devices vulnerable to cyberattacks.

This blog post will discuss the different types of wireless networks, how they work, and the security measures you need to take to keep your information safe. So if you’re ready to learn more about securing your data, read on!

What is Wireless Network Security?

Wireless security prevents unauthorized access or damage to computers using wireless networks. The most common type of wireless security is Wi-Fi security, which protects information sent through a Wi-Fi network.

Several different types of security measures can be used to protect Wi-Fi networks. The most common type of security is Wi-Fi Protected Access (WPA), a technology that was developed in response to the weaknesses of Wire Equivalent Privacy (WEP) (Mitchell, 2021).

WPA3 security is the most recent version of WPA and is the most secure of all Wi-Fi security types. WPA3 uses Advanced Encryption Standard (AES) to encrypt data sent over a wireless network.

What Type of Security Is Needed on a Wireless Network?

The type of security you need depends on the type of wireless network you have. If you have a home network, you may only need to use WPA2. However, if you have a business network, you may need to use cloud security best practices and other types of security, such as Virtual Private Networks (VPNs) or firewalls.

When configuring security for a wireless network, it’s important to use strong passwords and encryption. Changing your passwords regularly and using different passwords for different networks is also important. Avoid using personal information, such as your birthdate or mother’s maiden name, as hackers can easily guess these.

Why Is Wireless Network Security Important?

Wireless network security is vital because it helps protect your data from unauthorized access. Wi-Fi networks are particularly vulnerable to cyberattacks because they use radio waves to transmit data; this means that anyone within range of the Wi-Fi signal can potentially intercept and read the data being sent.

Cyberattacks are becoming more common and can have grave consequences on wireless network security. Hackers may be able to access sensitive information, such as credit card numbers or passwords, or they may be able to take control of devices on the network. This can lead to identity theft and financial loss.

Wireless network security is essential to protecting your data and devices from these risks. By taking measures to secure your Wi-Fi network, you can help to keep your information safe from hackers.

How Do I Secure My Wireless Network?

The best way to secure your wireless network is to use WPA2 security. WPA2 uses AES encryption, one of the most secure types of encryption available. You should also use strong passwords and change them regularly. The U.S. Cybersecurity and Infrastructure Security Agency suggests that users of wireless networks, whether individuals or enterprise, must continually change default passwords since they are susceptible to manipulation and only provide marginal protection. Additionally, you should avoid using personal information in your passwords.

If you have a business network, you may need to use other types of security, such as VPNs or firewalls. A cloud network security solution is also recommended to protect your data if your network is hacked. Other practical suggestions include maintaining antivirus software, carefully using file sharing systems, and protecting Service Set Identifier (SSID). You can read more about SSIDs here.

No matter what type of wireless network you have, it’s important to take measures to protect your information. By utilizing wireless security techniques, especially WPA2 security, and strong passwords, you can help keep your data safe from hackers.

What Are the Five Techniques Used for Wireless Security?

There are several different techniques that serve to improve the security of a wireless network. The most common techniques include:

◉ Encryption: This is the process of converting data into a code that authorized users can only decrypt.

◉ Firewalls: A firewall is a system that helps to block unwanted traffic from entering a network.

◉ Virtual Private Networks (VPNs): A VPN is a private network that uses encryption to secure data. VPNs can provide a secure connection between two networks or allow remote users to access a network.

◉ Intrusion Detection Systems (IDS): An IDS is a system that monitors activity on a network and looks for signs of intrusion. If an intrusion is detected, the IDS can take action to block the attacker.

◉ Access Control Lists (ACLs): An ACL is a list of permissions that specifies who can access a network resource.

What Are the Three Main Types of Wireless Encryption?

The three main types of wireless encryption are WEP, WPA, and WPA2. WEP is the least secure type of encryption and should only be used if necessary. WPA and WPA2 are more secure, and WPA2 is the most secure type of encryption available. When configuring wireless security, you should always use WPA2 if possible.

What Are WPA and WEP?

WEP is the Wireless Encryption Protocol, considered the least secure type of wireless encryption based on current standards. WEP uses a static key that is shared between all users on a network. This means that if one user’s key is compromised, all users on the network are at risk. WEP also uses weaker encryption than WPA and WPA2; it uses basic (64-/128-bit) encryption, which is hard to configure and susceptible to malicious manipulation.

WPA is the Wi-Fi Protected Access protocol. WPA uses a dynamic key generated and shared between networks. This means that if one user’s key is compromised, only that user is at risk. WPA also uses stronger encryption than WEP.

WPA2 is the most recent version of the Wi-Fi Protected Access protocol. WPA2 uses a dynamic key that is generated and shared between users on a network. WPA2 also uses stronger encryption than WEP and WPA.

Which Is the Strongest Wireless Security?

Presently, WPA3 is the strongest wireless network security system. It supersedes WEP, WPA, and WPA2, in providing security upgrades and wireless network security protection. WPA3 has better data encryption and key sharing capabilities than its predecessors (Sagers, 2021).

What Is the Difference Between WPA2 and WPA3?

WPA2 is the second most recent version of the Wi-Fi Protected Access protocol. WPA2 uses a dynamic key generated and shared between users on a network. WPA2 also uses stronger encryption than previous versions, including WEP and WPA.

WPA3 is the most recent generation of Wi-Fi security, offering more robust protection against potential threats. WPA3 uses enhanced encryption methods, making it more difficult for attackers to access data on a network.

WPA3 has additional security protocol features, including individualized data encryption, which encrypts each user’s data with a unique key. This means that even if one user’s data is compromised, the rest of the users on the network will remain safe. Others include greater protection for passwords and more security for enterprise networks. When configuring wireless security, you should always use WPA3 if possible.

What Is Enterprise Wireless Security?

Enterprise wireless security is securing network or providing wireless network security protection in an enterprise environment. Enterprise wireless networks are typically more extensive and complex than home networks, requiring more sophisticated wireless network security mechanisms. For instance, enterprise wireless security secures a network that connects systems, mainframes, and personal devices within organizations such as Government institutions, schools, and companies.

Enterprise wireless security measures include firewalls, access control lists (ACLs), intrusion detection systems (IDS), data leak prevention systems, and virtual private networks (VPNs). ACLs are often referred to as Identity and Access Management, especially in the business world. You can read more about these measures here. When configuring enterprise wireless security, you should always use the most secure methods possible to help protect your network from potential threats.

Why Are Enterprise Companies So Concerned About Wireless Network Security Threats?

Enterprise companies are genuinely concerned about wireless network security threats because they have sensitive data they need to protect. They hire wireless network security experts to help secure their data from potential security threats. Credible certifications for wireless network security experts like the Certified Network Defender (C|ND) show that an expert has the skills and knowledge needed to help secure an enterprise network.

Credible certifications make potential employers confident and comfortable with your competencies and your ability to deliver. C|ND certification assures your client that you know how to use the most secure methods to secure their enterprise networks.

Cyber forensics professionals are investigators that respond to cybercrime and serious data breaches. Organizations need cyber forensics to answer vital questions such as – what happened, how it happened, how bad it is, and who’s responsible.

A cyber forensic expert uses sophisticated techniques to get to the bottom of each incident. Their investigation is meticulous, focusing on creating a reliable evidence chain. The evidence they produce is admissible in court, which can help settle lawsuits—and bring cybercriminals to justice.

This kind of investigation is essential at a time when cybercrime is skyrocketing. The FBI’s digital unit investigated $6.9 billion in cyber fraud in 2021—a 500% increase in just five years (Federal Bureau of Investigation, 2021). The threat is real. That’s why there’s a growing demand for skilled, certified cyber forensics professionals.

What is Cyber Forensics?

Cyber forensics is the discipline of studying digital sources to find reliable evidence of serious data security incidents. A cyber forensics investigation involves looking for clues from sources such as physical devices, network logs, databases, and cloud services. The investigator will attempt to restore deleted data and may even search the dark web for information.

Data integrity is the most crucial part of cyber forensics. If there is any data loss or contamination, it could undermine the whole investigation. That’s why digital forensics analysts always follow a strict process:

1. Identification: Find all data sources that might have relevant information.

2. Preservation: Secure the data to prevent erasure, tampering, or contamination.

3. Analysis: Put all the data together and establish what happened.

4. Documentation: Build a detailed timeline of all known events and actors involved in the incident.

5. Presentation: Summarize the findings in an appropriate format.

Cyber forensics is a vitally important job, and not only in the fight against cybercrime. Digital evidence now plays a role in over 90% of all criminal trials (Yawn, 2015). Justice depends on having access to digital evidence that is reliable, objective, and accurate.

Why is There a Growing Demand for Certified Cyber Forensics?

Businesses are currently fighting for their lives against the constant threat of cyberattacks. Data breaches are expensive, costing up to $180 per individual record compromised (IBM, 2021). A data breach can also expose a business to sabotage, espionage, or extortion.

Responding to security incidents isn’t easy. It can take up to 287 days—over nine months—to identify and repair a data breach (IBM, 2021). During that time, the organization will lose vital data that could help track down the criminals responsible.

To fight back, many companies are hiring extra in-house computer forensics experts or working with forensic cybersecurity consultants. These experts are helping to deal with a wave of new threats, including:

◉ Rapidly changing technology: Sudden changes in information technology infrastructure can create new risks. For example, the switch to remote work during Covid led to a 220% increase in phishing attacks (Warburton, 2021).

◉ IoT vulnerabilities: There are over 13 billion Internet of Things (IoT) devices online (Statista, 2021). Not all these devices are secure, making them targets for hackers. These devices can also serve as hosting grounds for botnet attacks.

◉ Cryptocurrency: Cryptocurrency is hard to trace. That makes things much easier for ransomware attackers and much harder for cyber forensics analysts. $14 billion of criminal activity involved cryptocurrency in 2021, up 79% in 2020. (Chavez-Dreyfuss, 2022)

◉ Accessible hacking tools: Wannabe cybercriminals can now pay to access sophisticated hacking tools. This ease of access means more frequent attacks and more pressure on cyber defenses.

◉ Anti-forensics techniques: Criminals keep finding new ways to cover their tracks. Evolving anti-forensics techniques can make detecting and investigating a cyber-attack even harder.

The average business spends 10% of its annual IT budget on cybersecurity (Deloitte, 2020), most of which goes on prevention. But, when their defenses fail, those companies need cyber forensic professionals to investigate and find answers—fast.

Is Cyber Forensics a Promising Career?

As long as there is cybercrime, there will be a demand for cyber forensic analysts.

Full-time salaries for digital forensics professionals average at around $74,902 (Payscale, 2022). You can also work as a private consultant, which would mean billing clients according to your hourly rates.

You will need strong technical training and IT knowledge to succeed as a cyber forensic professional. You’ll also need the right qualifications (see next section) and experience in cybersecurity.

Most of all, you will need the right personal qualities, such as:

 

◉ Curiosity: You’ll need an insatiable desire to find the truth. A cyber forensic professional will ask questions, chase every lead, and explore every possible data source in the search for clues.

◉ Attention to detail: You’ll need to be able to spot patterns and clues in the smallest traces of data. You’ll also need to be painstaking in following the correct process.

◉ Continuous learning: Hacking techniques are constantly evolving—and so are anti-forensics strategies. You’ll need a voracious appetite for learning about the latest trends.

◉ Strong communication: You may need to present your evidence to non-technical people. Can you explain your findings to executives, law enforcement, or even a jury?

Cyber forensics can be a steppingstone to a senior career in cybersecurity. This path can lead to jobs like security architect or Chief Information Security Officer (CISO).

How to Become a Certified Cyber Forensics Professional

If you think cyber forensics is the right choice for you, then here’s the good news: there’s never been a better time to start.

Employers need cybersecurity people at all levels, from entry-level cyber forensics positions to senior consultants. These positions allow you to get hands-on experience and to see how cyber forensics works in the real world.

Some training options can help make you eligible to apply for vacancies. Here are a few cyber forensic courses to consider:

◉ Beginner: Got an IT background and are looking to pivot to security? Consider a security basics course. The Certified Network Defender program is an excellent place to start. You will learn about entry-level cyber forensics techniques, including risk anticipation, threat assessment, and endpoint security.

◉ Intermediate: What if you have security experience and want to develop your skills? A qualification such as Cyber Threat Intelligence Training gives an in-depth guide to threat analysis. You’ll also learn some of the data-gathering techniques involved in an investigation.

◉ Cyber forensics professional: When you’re ready for a serious career in cyber forensics, you can enroll in a program such as Computer Hacking Forensic Investigator (C|HFI) program. Here, you’ll gain in-depth knowledge about conducting a cyber forensics investigation on any platform and methods for counteracting anti-forensics techniques.

How to Understand, Design, and Implement Network Security Policies

One of the most important elements of an organization’s cybersecurity posture is strong network defense. A well-designed network security policy helps protect a company’s data and assets while ensuring that its employees can do their jobs efficiently. To create an effective policy, it’s important to consider a few basic rules.

What Is a Network Security Policy?

A network security policy (Giordani, 2021) lays out the standards and protocols that network engineers and administrators must follow when it comes to:

◉ Identifying which users get specific network access

◉ Determining how policies are enforced

◉ Choosing how to lay out the basic architecture of the company’s network environment

The policy document may also include instructions for responding to various types of cyberattacks or other network security incidents.

Types of Security Policies

◉ A general security policy defines the rules for secure access to company resources, including which users can access certain systems and data and what level of authentication is required.

◉ An acceptable use policy establishes guidelines for appropriate employee behavior when using company resources, including the internet and email.

◉ A data destruction policy specifies how long data should be retained and what steps must be taken to destroy or delete it once that time has elapsed.

◉ An incident response policy outlines the steps to take in a security breach or attack, including who should be notified and what type of action should be taken.

◉ An authentication policy defines how users are verified when accessing the organization’s networks.

◉ An encryption policy determines how data is encrypted to prevent unauthorized individuals from accessing it.

Basic Rules for Developing Security Policies

When designing a network security policy, there are a few guidelines to keep in mind.

◉ Tailor the policy to your specific business needs. When crafting a policy, it’s important to consider things like the size of the company, the type of data it stores, and the network security risks it faces.

◉ Keep the policy easy to understand and follow. It’s essential to keep network security protocols simple and clear so that employees can easily comply with them.

◉ Update the policy regularly. As new threats emerge that may endanger the organization’s networks, security teams need to update policies to reflect them.

◉ Enforce the policy consistently. Network security protocols need to apply equally to everyone, no matter their position within the company.

◉ Train employees on how to apply the policy. Organizations should provide employees with regular training on the network security policy to make sure that everyone knows what is expected of them.

How to Design and Implement Network Security Policies

When creating a policy, it’s important to ensure that network security protocols are designed and implemented effectively. Companies can break down the process into a few steps.

Assess the Current State of the Network

This step helps the organization identify any gaps in its current security posture so that improvements can be made. At this stage, companies usually conduct a vulnerability assessment, which involves using tools to scan their networks for weaknesses. Companies must also identify the risks they’re trying to protect against and their overall security objectives.

Develop a Plan

Once the organization has identified where its network needs improvement, a plan for implementing the necessary changes needs to be developed. It’s essential to determine who will be affected by the policy and who will be responsible for implementing and enforcing it, including employees, contractors, vendors, and customers. Companies will also need to decide which systems, tools, and procedures need to be updated or added—for example, firewalls, intrusion detection systems (Petry, 2021), and VPNs.

Make Changes

This is where the organization actually makes changes to the network, such as adding new security controls or updating existing ones. One of the most important security measures an organization can take is to set up an effective monitoring system that will provide alerts of any potential breaches.

Test the Changes

It’s essential to test the changes implemented in the previous step to ensure they’re working as intended. Companies can use various methods to accomplish this, including penetration testing and vulnerability scanning.

Monitor the Network

Even if an organization has a solid network security policy in place, it’s still critical to continuously monitor network status and traffic (Minarik, 2022). This includes tracking ongoing threats and monitoring signs that the network security policy may not be working effectively. It’s also helpful to conduct periodic risk assessments to identify any areas of vulnerability in the network.

Security leaders and staff should also have a plan for responding to incidents when they do occur. Consider having a designated team responsible for investigating and responding to incidents as well as contacting relevant individuals in the event of an incident.

The Need for Network Security Professionals

With the number of cyberattacks increasing every year, the need for trained network security personnel is greater than ever. Businesses looking to create or improve their network security policies will inevitably need qualified cybersecurity professionals.

Cybersecurity is a complex field, and it’s essential to have someone on staff who is knowledgeable about the latest threats and how to protect against them. If you’re looking to make a career switch to cybersecurity or want to improve your skills, obtaining a recognized certification from a reputable cybersecurity educator is a great way to separate yourself from the pack.

EC-Council’s Certified Network Defender (C|ND) program, designed for those with basic knowledge of networking concepts, is a highly respected cybersecurity certification that’s uniquely focused on network security and defense. The C|ND covers a wide range of topics, including the latest technologies and attack techniques, and uses hands-on practice to teach security professionals how to detect and respond to a variety of network cyberthreats.

How to Prevent Network Security Attacks

Five Ways to Defend Against Network Security Threats

Businesses of all sizes are susceptible to network security threats. Since hackers and cybercriminals are always looking for new ways to exploit network vulnerabilities, business owners must take steps to protect their data and infrastructure. This article will discuss five ways to prevent network security threats.

The Importance of Network Security

Before we discuss specific methods for thwarting network threats, it’s essential to understand the importance of network security. Having a secure network is vital to protecting data and preventing unauthorized access to systems. Additionally, maintaining a secure network can be part of meeting compliance requirements and protecting brand reputation (Bailkoski, 2021). Businesses that neglect network security are more likely to experience data breaches, which can be costly and damaging.

Common Network Security Threats

Businesses can face many types of threats to their networks. Some of the top network security risks include:

◉ Malware. Malware is a term used to describe a wide range of malicious software, including viruses, trojans, and spyware. Malware can be installed on a system without the user’s knowledge, where it can then cause damage or steal data.

◉ Spyware. Spyware is software that collects information about a user without their knowledge. It can track what websites a target visits and collect sensitive data, like passwords and credit card numbers.

◉ Phishing. Phishing attacks involve sending fraudulent emails or text messages to obtain sensitive information from recipients. The messages may appear to come from a legitimate source, such as a bank or credit card company, but are in reality sent by scammers.

◉ Ransomware. Ransomware is malware that locks users out of their computer or mobile device until a ransom payment is made. Ransomware viruses can be challenging to remove and can damage or delete files on a user’s system.

◉ Distributed Denial-of-Service (DDoS) attacks. A DDoS attack is one of the most dangerous types of security threats (Mathew, 2021). It is a type of cyberattack in which multiple systems flood a target with traffic, making it unavailable for legitimate users. DDoS attacks can be very costly and difficult to defend against.

How to Prevent Network Attacks

There are many different ways to defend against network-related threats. Here are five of the most effective methods.

1. Install antivirus software.

One of the first lines of defense against malware and other viruses is to install antivirus software on all devices connected to a network (Roach & Watts, 2021). Antivirus software can detect and prevent malicious files from being installed on a system, and it should be updated regularly to include the latest definitions.

2. Create strong passwords.

Another essential step in protecting a network is to create strong passwords. Passwords should be at least eight characters long and include a mix of letters, numbers, and symbols. They should also not be easy to guess—for instance, the user’s name or the name of the company.

3. Enforce security policies.

A third way to reduce risk of attacks on a network is to enforce security policies. Security policies can help ensure that all devices on a network are protected against viruses and malware and that users are using strong passwords. These policies can also restrict access to some network regions and limit user privileges.

4. Use firewalls.

Firewalls are another essential tool in defending networks against security threats. A firewall can help prevent unauthorized access to a network by blocking incoming traffic from untrusted sources. Additionally, firewalls can be configured to allow only certain types of traffic, such as web traffic or email.

5. Monitor activity.

Finally, it’s important to monitor activity on the network. Tracking logs and other data enables suspicious activity to be identified quickly, allowing security personnel to take steps to investigate and mitigate potential threats.

Consequences of Network Breaches

Network security breaches can have severe consequences for businesses, including:

◉ Data loss. A network security breach can result in the loss of sensitive data, such as customer information or financial records.

◉ Damage to reputation. A breach can also damage a company’s reputation and make it difficult to regain the trust of customers and other stakeholders.

◉ Loss of revenue. In some cases, a network security breach can lead to a loss of revenue as customers take their business elsewhere.

◉ Increased costs. Breaches can also lead to increased costs, such as hiring new staff or upgrading security systems.

How to Become a Network Security Engineer

Network Security Tools: Advantages and Disadvantages of Using a VPN

Imagine falling victim to a stalker who is hell-bent on tracking you everywhere you go. When you don’t wish to fall into a situation like this in real life, why should your online life be any different? Cyber criminals don’t always directly attack your system and steal data. Sometimes they track you and keep an eye on your activities for long-term gains. In real life, you’d install security cameras or burglar alarms to counter such problems. But in cyberspace, you will have to get effective network security tools to counter these problems.

Learn More: 312-38: Certified Network Defender

VPNs have been popular network security tools for almost half a decade. Their advantages make them effective in households as well as in organizations. But are VPNs actually effective in hiding your tracks online? The answer may surprise you. While the tool does have its advantages, it has its fair share of disadvantages as well. Here is everything you need to know if you are considering buying a VPN.

What Is a VPN?

A VPN or virtual private network is an encrypted connection between two machines. It affords you the security to connect with the desired network. You can use it to bypass geo-restricted content, protect your data from malicious hackers by hiding your personal IP address, and encrypt online traffic.

VPNs are good for organizations that need more than network security monitoring tools. They play an important role in establishing a secure remote office environment. They make sure that your remote workforce can log on to your office network from wherever they are and access company data. In the U.S. itself, the number of remote work employees has increased from 17% to 44% after the pandemic hit. In an environment like this, conventional network security tools will not prove highly effective. As a solution, VPNs are being recommended among remote work employees.

Use of VPN in Network Security

VPNs are online services that rely on a VPN client and VPN server to offer you a secure connection. Basically, when you install a VPN on your smart device or PC, it connects to another computer (server). The connection requests are encrypted before they are sent to the server.

Your PC or smart device will then use the server’s information to traverse the internet instead of its original network information. Thus, any site tracking user data would see the VPN server’s information instead of your own device’s information, making it one of the simplest but most convenient network security monitoring tools.

However, there is a misconception that VPNs are always safe and effective. The tool comes with certain pros and cons that you should weigh before getting one for yourself.

Advantages of a VPN

There are many advantages to using a secure private network.

Access Region-Specific Content

A VPN allows you to bypass geo-locked content. Most websites use the geolocation feature to acquire the actual location of a user. This information allows them to use geo-locking features to restrict site access only to people from certain countries. However, a VPN would make it look like your connection is coming from the location where the content is available, thus allowing you to access the content of these websites.

Secure Remote Office Connections

With COVID-19 necessitating the adoption of remote work culture, organizations have been saddled with strengthening their network security measures. Valuable consumer information and other sensitive information is more at risk with employees working from home. Unregulated access to an organizations’ documents and consumer data can be destructive to a business. Nevertheless, when you connect to business-related networks through a VPN, it ensures that your sensitive information is concealed behind the bogus information offered through the VPN.

Cost-Effective Network Security

New network security monitoring tools are being released almost daily. However, the latest software can be costly for businesses and may even trigger more issues. Organizations can use VPN services to prevent steep licensing fees and other expensive monthly charges. Although VPNs may not block intruders and scan for viruses, it avoids the need for those features by making you better protected online.

Disadvantages of a VPN

A VPN is not without its disadvantages, and although the pros overshadow the cons, there’s no harm in knowing about some important facts.

Most VPNs Allow Limited Sharing

While VPNs are cost-effective for an individual or small business, it often proves costly to set up in a big workplace. Most VPNs cost between $80 to $200 for a one-year subscription. If the organization exceeds more than 30-50 staff, costs will quickly add up as most software allow sharing between 5-8 devices at most.

Data Transfers Slow Down Connection Speeds

A VPN slows down connection speeds since the connection is virtual and occurs inside a physical network. Routing web traffic from your ISP (Internet Service Provider) to your VPN and vice versa will slow down your connection.

Multiple Limitations for Gamers

If you are a gamer, you’d understand the pain of slow connection and lagging speed while playing a multiplayer mission. Using a VPN during gaming sessions can be frustrating because of the slow connections. Apart from that, many gaming platforms don’t allow VPNs, and if you are using a cheaper software, then your account may get banned permanently.

VPNs are easy to install and execute. It is a versatile network security tool. But irrespective of these advantages, you should never install a VPN without an expert who has received network security certification training and knows about using the admin tool to secure your wireless network. His/her assistance will help you understand different VPNs, the best connectivity options, and the most advantageous way to distribute them among your employees.

Get Network Security Training with EC-Council

EC-Council offers beginner-level, intermediate-level, and advanced-level network security certification and training programs for professionals and those who desire to enter this field. The modules cover VPNs along with other network security tools in great detail. The program brings out the smallest aspects that may play an important role in strengthening computer network security.

EC-Council’s Certified Network Defender (CND v2) program is designed by cybersecurity experts to prepare the cybersecurity experts of the future. The program takes an elaborate approach to help an aspiring network security officer understand everything required to counter network security threats in this new era. The lab-intensive training covers different concepts through which you can prevent an attack, as well as predict and thwart one in advance.

What Is Defense in Depth?

Defense in depth (DiD) is an information assurance approach where several layers of defense are stationed all through an IT system. It tackles security vulnerabilities in technology, human resources, and operations throughout the system’s life cycle.

DiD derives from a military approach that tries to slow down the progress of an attack, instead of overwhelming it with a robust line of defense, in order to buy more time. The idea of the multi-layered defense approach is that if one approach fails, another would replace it. This increases the network defense of a system and addresses several attack vectors.

Join us as we unpeel the layers of defense in depth and get to the root of why it’s an essential component of a network defense strategy, along with the certifications that you would need as a professional  to perform this important role for Employers across the globe.

Why Is Defense in Depth Important?

Today, everything that connects one device to another needs a robust network defense strategy. Understanding and implementing defense in depth is essential, whether you’re a CISO looking to train your employees or cybersecurity professionals seeking new ways to battle old enemies.

Poor network defense practices without a robust defense in depth strategy can lead to businesses suffering malware attacks and phishing cons, leading to damages worth millions and theft of customer data as well as confidential information.

According to IBM, the global average cost of a data breach in 2020 was $3.86 million [1].

As data breaches are set to remain persistent and destructive in the future, the demand for strong network defense and solutions is increasing concurrently.

◉ Businesses can suffer malware attacks, phishing, and human mistakes leading to damages worth millions. Poor network defense practices lead to these issues. Almost every industry sector has been a victim of an attack like this in 2020. Attackers misuse customer data as well as confidential information for their malicious intentions. To ensure that their operations continue with ease, they should always take help from network defense experts.

◉ Professionals need to learn about network defense strategies because it helps raise awareness and improves their online practices. Multiple attacks worldwide have happened because the unaware employees of an organization mistakenly share confidential information with hackers. Through better network security policies, professionals will understand how to avoid such attacks and inform the cybersecurity team before a major incident happens.

◉ Understanding network security practices is also important for students, especially those who are planning to pursue a career in IT or cybersecurity. Initial understanding of network security will help them stay a step ahead during their learning stage as well as in their professional career.

What Are the Key Layers of Defense in Depth?

Administrative controls: These are security essentials that comprise the procedures or policies directed at an organization’s personnel, such as charging users to tag sensitive information as “classified.”

Any control: These controls are directed at an organization’s employees and vendors. Examples include:

◉ Information security policies

◉ Vendor risk management

◉ Third-party risk management frameworks

◉ Cybersecurity risk assessments

◉ Information risk management strategies.

Technical controls: These comprise security essentials that secure network systems or resources through specified hardware or software. Technical controls refer to the software security measures that are installed in the IT infrastructure, such as:

◉ Intrusion protection systems

◉ Web application firewalls

◉ Configuration management

◉ Web scanners

◉ Two-factor authentication

◉ Biometrics

◉ Timed access

◉ Password managers

◉ Virtual private networks

◉ At rest encryption

◉ Hashing

◉ Encrypted backups

Physical controls: These comprise security solutions that block physical access to IT systems. Some of the essential elements of physical controls include:

◉ Locks

◉ Security guards

◉ Surveillance cameras

◉ Keycards

◉ Motion detectors

◉ Demilitarized zones

Network Security Policies

An organization’s network security policy is a document that specifies the security outlooks of the organization. It is an official guideline that mandates users authorized to an organization’s resources, technology, and assets to comply with the laid down rules.

In order to implement a security policy, it is important to outline the precise policy that you intend to implement. Sometimes, these security measures turn out to be exceptionally restricting.

The following policies are enforced by organizations to protect their systems and other critical assets:

◉ Internet access

◉ Device security

◉ Wireless LAN

◉ Remote connection

◉ Intrusion

◉ VPN

◉ Port communication

◉ Firewall rules

◉ DMZ policy

◉ Secure communication policy

◉ Proxy server policy

Network Security Techniques

You need to possess the right techniques and tools to protect your network data from malicious threats and save your organization from destructive losses. Your technique requires you to know how to protect, detect, respond, and predict a broad range of attacks. Defense in depth solutions fall under the protective technique. Key techniques and tools include:

◉ Access control: This allows you to improve your network security by restricting user access and resources to just the sections of the network that clearly relate to the user.

◉ Antimalware and antivirus software: These are network security software created to detect vampiric programs and stop them from spreading.

◉ Anomaly detection: A standard understanding of how networks help you recognize anomalies. You can implement network anomaly detection engines (ADE) to evaluate your network. When you notice an anomaly, you can quickly respond to them.

◉ Application security: This establishes security considerations for critical applications to your network security.

◉ Data loss prevention (DLP): This helps prevent personnel and other users from abusing and potentially compromising valuable data.

◉ Endpoint security: This includes an additional layer of defense between organizational networks and remote devices.

◉ Intrusion prevention systems: IPD/IDS protect the database of known attack vectors so threats can be recognized instantly.

◉ Network segmentation: This helps you give the appropriate access to the appropriate traffic while controlling the traffic from suspicious sources.

◉ Web security: This helps prevent web-based threats such as malicious websites, malicious scripts, or adware programs from leveraging browsers as access points to penetrate a network.

Why Do We Need Hybrid Network Security?

Security threats have progressed from being single attacks to becoming an intricate blend of threats. For instance, Distributed Denial of Service (DDoS) attacks are currently introduced by tens of thousands of Internet of Things (IoT) devices.

Even with more traffic being encrypted, security applications still find it hard to detect threats. Cybersecurity professionals and teams are saddled with the overwhelming responsibility to recognize and protect against multifaceted threats.

Hybrid network security includes virtualization, software-defined networking (SDN), and application support across all layers of the service mesh, spanning various hardware devices and data centers. Many applications are applied collectively as a joint solution for defense in depth. It often includes a series of active and passive security applications.

One recognized method of tackling security threats is to construct a visibility fabric through network packet broker (NPB) appliances and virtual agents, alongside network tapping.

Verizon’s 2020 Data Breach Investigations Report states that 2020 has seen major cyberattacks across different verticals.

The worst-affected sectors were:

Gear Up for the Next Stage of Cyber Defense
