“Cybersecurity is much more than a matter of IT.” ― Stephane Nappo.

As we progress in our digitalization, the chances of becoming a target to damaging cyberattacks increases. While there is no way to stop the occurrence, staying vigilant and adopting a holistic security approach is key to surviving the attacks. The evolving threat landscape today emphasizes the need to analyze and dive deep into the core of cybersecurity, its evolution, and its role in preventing cyberattacks. So, what is cybersecurity, and why is it so important today? This article will discuss everything you must know about cybersecurity: what it is all about, its importance and benefits, the best career opportunities in the domain, and more.

Cybersecurity Definition and Meaning

Cybersecurity is popularly defined as the practice of implementing tools, processes, and technology to protect computers, networks, electronic devices, systems, and data against cyberattacks. It is adopted by individuals and enterprises to limit the risks of theft, attack, damage, and unauthorized access to computer systems, networks, and sensitive user data. Since its inception in the 1970s, cybersecurity has undergone constant evolution. Today, cybersecurity is no longer restricted to the practice of only protecting computers but also individuals against malicious cyberattacks. The main purpose of cybersecurity is to prevent the leak of sensitive data while simultaneously ensuring cyber resilience to respond and recover from cyberattacks with lesser damage.

Different Types of Cybersecurity

As cyberattacks become more innovative and complex, the scope and domains expand to encompass several disciplines. Based on its application areas, cybersecurity can be broadly classified into six distinct types:

◉ Application Security: While app integration into business models has streamlined operations, they have also created potential for new security vulnerabilities. Application security is the process of integrating security mechanisms into web applications and programs to protect data against theft, unauthorized access, and damage.

◉ Network Security: Network security refers to the process of safeguarding internal computer networks and network components against cyberattacks by employing strong network security solutions like firewalls, anti-virus, anti-malware programs, data loss prevention (DLP)s, and other multi-layered threat prevention technologies.

◉ Infrastructure Security: This is the practice of safeguarding an organization’s critical infrastructure against cyberattacks. Unlike traditional perimeter-focused security models, organizations that rely on critical infrastructure must implement best practices and adopt “zero-trust” to protect their critical infrastructure against evolving cyberthreats.

◉ Cloud Security: Cloud security is the discipline of implementing security measures, policies, and technologies to protect cloud data and cloud computing systems from cyberthreats.

◉ Mobile Security: This is a security strategy implemented to protect sensitive information stored on mobile devices such as laptops, smartphones, and tablets from unauthorized access and data theft.

◉ IoT Security: While IoT solutions ensure operational efficiency and convenience, they create possibilities for new security vulnerabilities too. IoT security is the act of employing tools and techniques to protect internet-connected devices from security risks.

Most Common Types of Cybersecurity Threats

To understand cybersecurity better, it is important to know more about various cybersecurity threats and their damaging repercussions on businesses and individuals. While there can be various motives behind cyberthreats, the primary rationale seems to be financial gain. The major types of cybersecurity threats that are widely prevalent today include the following:

◉ Malware: Malware or malicious software are viruses, trojans, ransomware, spyware, etc., designed to gain unauthorized access to computer systems, servers, or networks. Malware can steal, delete, and encrypt data, disrupt business operations, and destroy computer systems.

◉ Password Attack: Password attacks are one of the most prevalent cyberattacks, in which the attacker employs special techniques and software to hack password-protected files, folders, accounts, and computers.

◉ Phishing: Phishing, the most common form of password attack, is sending fraudulent communications to targets over emails, texts, and calls, while pretending to be from reputable and legitimate institutions. Phishing attacks are generally performed to steal personal user data, login credentials, credit card numbers, etc.

◉ Distributed Denial-Of-Service (DDoS): DDoS attacks are attempts to disrupt and overwhelm a target website with fake or synthetically generated internet traffic. They are becoming increasingly common and aim to pose serious financial and reputational damages to an organization.

◉ Man-In-The-Middle Attack (MITM): MITM is a kind of eavesdropping cyberattack where an attacker joins an existing conversation between two legitimate parties, intercepts it, and secretly relays and alters conversations with the malicious intent to steal bank credentials and other financial information of the targets.

The Importance of Cybersecurity

With evolving cybercrimes causing havoc to enterprises and individuals, cybersecurity is increasingly important. Cybersecurity is essential to protecting individuals and businesses against diverse cyberthreats (as discussed above). It strengthens an organization’s defense posture and is critical in mitigation and response.

Edge Computing - Its Importance and Everything You Need to Know

With huge volumes of data being stored and transmitted today, the need for efficient ways to process and store that data becomes more critical. This is where edge computing comes in — we can improve performance and reduce latency by deploying processing power and storage closer to the data generation sources. Edge computing can help us manage our ever-growing data needs while reducing costs. This blog discusses the importance of edge computing, its advantages, and its disadvantages.

What Is Edge Computing?

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the location needed to improve response times and save bandwidth.

Read More: 312-50: Certified Ethical Hacker (CEH)

It involves putting resources physically closer to users or devices — at the “edge” of the network — rather than in centralized data centers. Edge computing can be used in conjunction with fog computing, which extends cloud-computing capabilities to the edge of the network.

Examples of Edge Computing

There are many potential applications for edge computing, including the following:

◉ Connected cars: Mobile edge computing can be used to process data from onboard sensors in real time, enabling features such as autonomous driving and real-time traffic monitoring.

◉ Industrial Internet of Things (IIoT): Edge network computing can be used to collect and process data from industrial sensors and machines in real time, enabling predictive maintenance and improved process control.

◉ 5G: Cloud edge computing will be critical for supporting the high bandwidth and low latency requirements of 5G networks.

Importance of Edge Computing

Edge computing can help to improve many aspects of an organization:

◉ The main importance of edge computing is to reduce latency and improve performance by bringing computation and data storage closer to the devices and users that need them.

◉ Multi-access edge computing can also help save on bandwidth costs and improve security by processing data locally instead of sending it over the network to central servers.

◉ Edge computing can be used in conjunction with other distributed computing models, such as cloud edge computing and fog computing. When used together, these models can create a more flexible and scalable system that can better handle the demands of modern applications.

How Does it Work?

Edge computing can be considered a compliment or an extension of cloud computing, with the main difference being that edge computing performs these computations and stores this data locally rather than in a central location.

Edge network computing nodes are often located at the “edge” of networks, meaning they are close to the devices that generate the data. These nodes can be deployed on-premises or in a colocation facility. They can also be embedded in devices, such as routers, switches, and intelligent sensors.

The data generated by these devices is then processed and stored locally at the edge node. This data can be analyzed in real-time or transmitted to a central location for further processing.

What Are the Benefits of Edge Computing?

The following are just some of the benefits of edge computing:

◉ Efficiency increases: Edge computing can make networks more efficient. When data is processed at the edge, only the needed data is sent to the central location, rather than all data being sent and filtered at the central location.

◉ Security improvements: Cloud edge computing can also improve security. By processing data locally, sensitive data can be kept within the network and away from potential threats.

◉ Reduction of latency: Edge computing can help to reduce latency. Processing data at the edge of the network, close to the source of the data, means there is no need to send data back and forth to a central location, which can take time.

What Are the Disadvantages of Edge Computing?

One disadvantage of cloud edge computing is that it can introduce additional complexity to the network. This is because data must be routed to the appropriate location for processing, which can require extra infrastructure and management.

In addition, edge computing can also be less reliable than centralized processing, as there may be more points of failure.

Another potential disadvantage of edge computing is that it may only be suitable for some applications. Examples include applications that require real-time processing or that are particularly latency-sensitive.

Why Is Edge Computing More Secure Than Centralized Processing?

Edge computing is more secure for several reasons.

◉ First, data is stored and processed at the edge of the network, closer to the source of the data. This reduces the time data is in transit and the chances that data will be intercepted.

◉ Second, data is processed in a distributed manner, meaning that if one node in the network is compromised, the rest of the network can continue to function.

◉ Finally, edge computing systems are often designed with security in mind from the ground up, with security features built into the hardware and software.

Edge vs. Cloud vs. Fog Computing vs. Grid Computing

There is no one-size-fits-all answer to which type of computing is best for a given organization. It depends on the specific needs and goals of the organization. However, some general trends can be observed.

◉ Organizations are increasingly moving towards cloud computing, as it offers many advantages in terms of flexibility, scalability, and cost-efficiency.

◉ Edge computing is also becoming more popular because it can provide faster data processing and improved security.

◉ Fog computing is another option that is gaining traction. Fog computing offers many of the benefits of cloud computing but has lower latency.

◉ Grid computing is typically used for high-performance applications that require large amounts of data to be processed in parallel.

Edge computing comes with numerous security challenges that cybersecurity professionals need to know of to keep their IT infrastructure and systems secure. With IoT devices growing at an unprecedented rate, the way data is analyzed and transmitted is also evolving. So, IT and security professionals need to acquire the latest best practices to safeguard their edge computing infrastructure.

How Can You Test the Strength of a Disaster Recovery Plan?

The widespread adoption of technology has changed how businesses process information. Employees today communicate using email and VoIP telephone systems and use electronic data interchanges to transmit orders between companies or payments from one account to another. All of these systems rely on IT to function correctly.

As business processes become increasingly reliant on IT, organizations also need to be prepared for the growing risk of cyberthreats. In this environment, it’s important to ask yourself what policies and procedures your organization has in place in the event of a disaster. IT disaster recovery plans (DRPs) and business continuity plans (BCPs), which provide a roadmap for response and recovery in the event of a crisis, are essential to have on hand in an emergency. But how can you ensure your plans will work?

The answer is testing. Before you implement your DRP and BCP in production environments, you need to ensure that your unit tests and user simulation exercises have covered every step in the process. In this article, we’ll outline the best practices for testing your organization’s DRPs and BCPs and explain how EC-Council’s Disaster Recovery Professional (E|DRP) certification can benefit you.

Testing a Disaster Recovery Plan: How to Avoid Different Types of Cyberattacks

The best way to ensure that your DRP is working properly and will assist you in an emergency is to test it regularly. All businesses should have a recovery plan in place. However, many don’t take action until something goes wrong, leaving them vulnerable until their next scheduled test date.

A BCP and DRP provide guidelines for your organization to follow in an emergency. Since no one knows when a disaster will strike, it is essential to have well-crafted BCP and DRP tests that account for as many potential types of cyberattacks as possible.

Set Your Plans and Objectives

Before you begin to test your disaster recovery system, you should identify the relevant key performance indicators (KPIs). The most common KPIs for disaster recovery solutions are recovery time objective (RTO) and recovery point objective (RPO). RTO describes the amount of time that can elapse after the failure of a system before your business is impacted. RPO indicates the maximum acceptable amount of data loss after an emergency occurs by calculating how much time can elapse since the last backup if it becomes necessary to restore from tapes rather than online services.

While there is no one standard for how often you should test your DRP and BCP, you should generally conduct functional disaster recovery testing at least once per year. This should include an emergency evacuation drill; a structured walkthrough; and a review of your risk assessment, business impact analysis (BIA), and recovery plans. A checklist test should be conducted twice per year. Recovery simulation tests or drills should be conducted at least every two or three years or as you deem fit for your business.

Although these guidelines are the most commonly suggested, it’s not always necessary to follow them strictly. The time frames for your testing should reflect your organization’s size, industry, personnel, BCP maturity levels, and available resources. EC-Council advises that you assess, review, and update your emergency preparedness plans throughout the year, including your DRP, BCP, risk management plan, and incident response plan.

Create a Test Environment

You can improve the accuracy of your tests by paying close attention to detail when setting up your lab environment. In testing environments, you should mirror your production hardware and software as closely as possible so there are no surprises in real-world situations later on. Know the types of cyberattacks to which you’re most susceptible and create an appropriate testing environment.

Choose the Right Testing Method

Those working on your disaster recovery solution should assess what’s needed to ensure your business is prepared when a crisis arises. They should then proceed through every step—from policies to procedures to checklists—so no potential deficiencies are left unaddressed. A physical copy should be stored securely, while digital copies can reside on cloud servers accessible by multiple computers or smartphones.

Relying on only one testing technique can’t ensure that your plan will be effective in an emergency. Instead, you should conduct a variety of tests before implementing any changes to production environments. This may include performing user research (for example, asking people if they would like certain features) and testing interactions with software tools or physical devices necessary for the BCP’s functionality. Next, we’ll review some of the techniques that should be part of your testing scenario.

This stage often includes senior executives and department heads. They’ll assess the BCP and DRP, deliberate on likely developments, update contact information, and ensure that business continuity and disaster recovery situations are adequately addressed. Making a plan identifies the sequence in which crucial administrative and operational processes should be conducted. It is typically structured as a quick-reference guide.

Walkthroughs, also referred to as runthroughs, are used to support hands-on and procedural drills. This testing technique resembles structured walkthrough drills with department heads, which aim to ensure that the core delegation channels are informed of what’s expected of them in an emergency or disaster. This includes automated and scripted contingencies, data validation, cloud backups, data replication tasks, kickoff boot sequences, standby server switchovers, and other technical components of your BCP and DRP.

Simulation testing focuses on restoring and recovering key components of the DRP in superficially realistic situations. This type of testing involves performing real-life tests of outmoded systems, restoring from backups, and practicing loss recovery procedures, among other related activities. You should also test your protocols for staff safety, leadership response, asset management, and relocation.

Involve Your Vendors

During your testing cycle—that is, your checklist, walkthrough, and simulation—you should ensure that your key vendor is covered in the testing procedure. Including your vendors in your testing process lets you review and assess the precision and serviceability of your business plans to a greater extent. It also enables your vendors to offer feedback to support your testing activities and plans.

Record Your Tests or Drills

Ensure that you record and properly file the outcomes of your tests and drills, including documenting all findings that indicate a lack of compliance with applicable laws and regulations or that may otherwise lead to actionable outcomes. Once you’ve completed your drills and testing processes, record your findings, and adjust your DRP and BCP accordingly. It’s critical to monitor the results of your tests and integrate the suggestions realized through your testing process. This is the most appropriate method of reinforcing your company’s response techniques.

Types of Hackers

Hackers can be classified into three different categories:

1. Black Hat Hacker

2. White Hat Hacker

3. Grey Hat Hacker

Black Hat Hacker

Black-hat Hackers are also known as an Unethical Hacker or a Security Cracker. These people hack the system illegally to steal money or to achieve their own illegal goals. They find banks or other companies with weak security and steal money or credit card information. They can also modify or destroy the data as well. Black hat hacking is illegal.

White Hat Hacker

White hat Hackers are also known as Ethical Hackers or a Penetration Tester. White hat hackers are the good guys of the hacker world.

These people use the same technique used by the black hat hackers. They also hack the system, but they can only hack the system that they have permission to hack in order to test the security of the system. They focus on security and protecting IT system. White hat hacking is legal.

Gray Hat Hacker

Gray hat Hackers are Hybrid between Black hat Hackers and White hat hackers. They can hack any system even if they don't have permission to test the security of the system but they will never steal money or damage the system.

In most cases, they tell the administrator of that system. But they are also illegal because they test the security of the system that they do not have permission to test. Grey hat hacking is sometimes acted legally and sometimes not.
