Understanding the mechanisms behind these attacks is crucial for businesses to fortify their defenses and mitigate potential risks effectively.

What are DoS and DDoS Attacks?


DoS Attack

A DoS attack is a malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of illegitimate traffic. This influx of traffic exhausts the target's resources, rendering it inaccessible to legitimate users. Typically, a DoS attack is orchestrated by a single attacker using a single source to flood the target.

DDoS Attack

On the other hand, a DDoS attack involves multiple compromised devices, often referred to as a botnet, to flood the target with a massive volume of traffic simultaneously. The coordinated nature of DDoS attacks amplifies their disruptive capabilities, making them more challenging to mitigate compared to traditional DoS attacks.

How Do DoS and DDoS Attacks Work?


DoS Attack Mechanisms

DoS attacks exploit vulnerabilities in network protocols or applications to flood the target with excessive traffic. Some common techniques used in DoS attacks include:

  • SYN Flood: This attack floods the target server with a high volume of TCP connection requests, consuming its resources and preventing legitimate connections.
  • UDP Flood: In this attack, the attacker sends a large number of UDP packets to the target, overwhelming its capacity to process incoming data.
  • HTTP Flood: By sending an overwhelming number of HTTP requests to a web server, this attack aims to exhaust the server's resources, leading to downtime.

DDoS Attack Mechanisms

DDoS attacks leverage a network of compromised devices, often IoT (Internet of Things) devices infected with malware, to launch coordinated attacks against a target. These attacks can employ various techniques, including:

  • Botnets: A DDoS attack relies on a botnet, a network of compromised devices controlled by the attacker, to generate and direct traffic towards the target.
  • Amplification: Attackers exploit vulnerable services, such as DNS or NTP servers, to amplify the volume of traffic sent to the target, magnifying the impact of the attack.
  • Reflection: By spoofing the source IP address and sending requests to reflectors, attackers can direct amplified traffic towards the target, masking their identity.

Impact of DoS and DDoS Attacks


Financial Losses

DoS and DDoS attacks can result in significant financial losses for businesses due to:

  • Downtime: Service disruptions lead to lost revenue and productivity, especially for e-commerce platforms and online services.
  • Reputation Damage: Persistent attacks can tarnish the reputation of an organization, eroding customer trust and loyalty.
  • Mitigation Costs: Investing in robust cybersecurity measures and incident response mechanisms entails additional expenses for affected entities.

Operational Disruption

Beyond financial implications, DoS and DDoS attacks disrupt the normal operations of targeted entities, causing:

  • Service Unavailability: Users are unable to access essential services or resources, impacting their ability to carry out tasks.
  • Resource Exhaustion: Overwhelmed servers and networks struggle to handle legitimate traffic, resulting in degraded performance or complete outages.
  • Emergency Response: Organizations must allocate resources and manpower to mitigate the attack and restore services promptly, diverting attention from other critical tasks.

Mitigating DoS and DDoS Attacks


Proactive Measures

To enhance resilience against DoS and DDoS attacks, organizations can implement the following proactive measures:

  • Network Segmentation: Segmenting networks and implementing access controls can limit the impact of an attack by isolating affected areas.
  • Traffic Filtering: Deploying intrusion detection and prevention systems (IDPS) to filter and block malicious traffic in real-time.
  • Bandwidth Management: Utilizing bandwidth management solutions to prioritize legitimate traffic and mitigate the impact of volumetric attacks.
  • DDoS Protection Services: Leveraging specialized DDoS protection services offered by cybersecurity vendors to detect and mitigate attacks effectively.

Incident Response

In the event of a DoS or DDoS attack, organizations should enact a well-defined incident response plan, including:

  • Early Detection: Monitoring network traffic and system performance to detect anomalies indicative of a potential attack.
  • Traffic Analysis: Analyzing incoming traffic patterns to identify malicious sources and techniques employed by attackers.
  • Mitigation Strategies: Implementing countermeasures such as rate limiting, traffic redirection, or IP blacklisting to mitigate the impact of the attack.
  • Communication Protocol: Maintaining open lines of communication with stakeholders, including customers, partners, and regulatory authorities, to provide timely updates and manage expectations.

Conclusion

DoS and DDoS attacks represent formidable threats to the availability, integrity, and confidentiality of online assets. By understanding the mechanisms behind these attacks and implementing proactive cybersecurity measures, organizations can safeguard their digital infrastructure and minimize the risk of disruptive incidents.

Methodologies and Techniques


Packet Capture and Analysis

Central to network forensics is the process of packet capture, wherein network traffic is intercepted and recorded for subsequent analysis. This technique involves deploying sensors or network taps at strategic points within the network infrastructure to capture data packets traversing the network. Subsequently, forensic analysts utilize specialized software tools to dissect captured packets, extracting valuable information such as source and destination IP addresses, protocols, timestamps, and payload contents.

Signature-based Detection

Signature-based detection techniques involve the comparison of network traffic patterns against predefined signatures or attack patterns associated with known cyber threats. By employing signature-based Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS), organizations can automatically identify and block malicious activities, including malware infections, denial-of-service (DoS) attacks, and SQL injections, thereby fortifying their network defenses against common cyber threats.

Heuristic Analysis

In contrast to signature-based approaches, heuristic analysis techniques focus on identifying suspicious behavior based on deviations from normal network activity. By establishing baseline network behavior through continuous monitoring and statistical analysis, heuristic detection mechanisms can flag anomalies such as unusual data transfers, port scanning activities, or unauthorized access attempts. This proactive approach enables organizations to detect novel or previously unseen threats that may evade traditional signature-based defenses.

Real-World Applications


Incident Response and Investigation

In the event of a security breach or suspected cyber incident, network forensics plays a crucial role in facilitating incident response and forensic investigation efforts. By reconstructing the sequence of events leading up to the incident, analyzing compromised systems, and identifying the root cause of the breach, forensic analysts can provide vital intelligence to support remediation efforts and strengthen cyber resilience.

Regulatory Compliance and Legal Proceedings

Furthermore, network forensics serves as a cornerstone in ensuring regulatory compliance and supporting legal proceedings related to cybersecurity incidents. By maintaining detailed logs of network activity, preserving digital evidence, and adhering to established forensic protocols, organizations can demonstrate due diligence in protecting sensitive data and complying with industry regulations such as GDPR, HIPAA, or PCI-DSS.

Clearing Logs in Cybersecurity: Why and How to Clear Logs

Clearing Logs in Cybersecurity: Why and How to Clear Logs

Logs are digital records that collect information on the events within a computer system or network. There are many different reasons to maintain logs, from helping with troubleshooting to monitoring user activity.

In the context of cybersecurity investigations, “clearing logs” refers to the action of intentionally deleting or removing log entries. While there are legitimate reasons to clear event logs, organizations need to ensure that they comply with the applicable laws and regulations and avoid the potential risks of doing so. This article will discuss everything you need to know about clearing logs: what it is, how to do it, the risks and consequences of doing so, and more.

Why Do Organizations Maintain Logs?


Organizations maintain logs (also known as “log retention”) for a variety of reasons, including:

  • Troubleshooting and performance monitoring: Logs can record information about errors, technical problems, and performance issues within an IT environment. This data can be invaluable in helping IT administrators detect and resolve concerns.
  • Audits: External auditors may require organizations to keep logs as part of regulatory compliance requirements for laws such as HIPAA and GDPR. These logs prove user activities and system processes, confirming that the business has not violated laws or guidelines.
  • Incident detection and response: Time is of the essence when a cyberattack occurs, and log monitoring can help IT security experts detect and respond to potential incidents more quickly. Logs record suspicious activities and anomalies that can be analyzed by SIEM (security information and event management) software.
  • Digital forensics: Following a cyberattack or other crime, logs can play a crucial role in digital forensics, helping security analysts reconstruct the chain of events. Logs offer insights into how the attackers entered the network and what they did after the breach.
  • Monitoring user activity: Logs record the actions of users within an IT environment, from the applications they use to the websites they visit. Businesses can use logs to keep track of user activity and ensure that they do not take unauthorized actions.

What Are the Ethical Considerations of Clearing Logs?


There are many good reasons to maintain logs; however, organizations may also wish to clear logs occasionally. The motives for clearing logs include:

  • Performing routine maintenance (for example, to free up storage space).
  • Deleting irrelevant data to help better monitor the IT environment.
  • Preserving the privacy of sensitive personal data (e.g., in accordance with laws such as GDPR).

Organizations should clear logs in a controlled and responsible manner, accounting for their business requirements and legal obligations. Below are some ethical considerations when clearing logs:

  • Transparency and accountability: Clearing logs can make it harder for organizations to remain transparent and accountable for their actions. Because logs record important IT events and user actions, clearing them without proper justification could be seen as an attempt to hide information.
  • Hampering investigations: As discussed above, logs can be valuable evidence when looking into events such as a cyberattack. Clearing logs may impede these investigations, making it difficult or impossible to determine the root cause of a security breach.
  • Legal and regulatory compliance: Maintaining logs may be necessary in the event of an audit or to comply with applicable laws and regulations. Organizations need to ensure that clearing logs does not prevent them from proving their compliance to external auditors.

How Can Logs Be Cleared?


The best way to clear logs is by using one of the various log management tools on the market. These solutions include Splunk, Datadog, SolarWinds Papertrail, Sumo Logic, and many more. Log management tools help users gather, store, and analyze the log data that they collect from the sources in their IT environment.

Logs can be cleared either manually or automatically:

  • Manually clearing logs involves the actions of human employees, such as system administrators and other IT personnel. Users manually inspect logs to determine if they need to be retained or can be deleted.
  • Automatically clearing logs involves the use of log management tools. Logs are automatically cleared when a specific event is triggered — for example, the log may be older than a specific date, or the system may have run out of storage space.

Whether clearing logs happens manually or automatically (or a mixture of both), organizations need to protect logs from unauthorized modification or deletion. The challenges and risks here include:

  • Accidents: Users may accidentally delete entries that should have been retained when manually clearing logs. Automatic log management tools may also be configured incorrectly, causing them to unintentionally delete important information.
  • Insider threats: Employees with hidden or malicious motivations may be insider threats, seeking to tamper with log data for their purposes. They might look to hide their actions or hinder the work of auditors or investigators.
  • Cyberattacks: Savvy attackers often attempt to clear logs to cover their own tracks after breaching an organization’s defenses. This requires them to acquire additional permissions within the IT environment, a technique known as privilege escalation.

What Are the Consequences of Clearing Logs?


When organizations clear event logs, this can have both intended and unintended consequences. Clearing logs can result in outcomes such as:

  • Incident response: If the logs of a security event are cleared, this can prevent organizations from effectively detecting and responding to intrusions.
  • Forensic investigations: Cleared logs may contain crucial information that could be evidence in a digital forensics investigation.
  • Legal proceedings: Organizations involved in legal proceedings may be subject to civil or criminal penalties if they destroy logs related to the case.
  • Reputational damage: Clearing logs can damage an organization’s customer reputation, lowering its transparency and accountability.
  • Regulatory compliance: Businesses may face repercussions from industry regulators and auditors who need to view log entries as part of their work.

How Can Organizations Ensure Log Integrity and Security?


In the face of these challenges and consequences, organizations need to preserve log integrity and security, only clearing logs when necessary. Below are some best practices when clearing logs:

  • Retention policies: Logs should be retained for at least as long as the applicable laws and regulations require them to be stored.
  • Access control: Organizations should restrict log access and deletion rights to employees with a solid business use case.
  • Encryption: Encrypting logs in transit and at rest can help prevent malicious actors from viewing them and tampering with their contents.
  • Secure storage: Logs should be stored in a secure place that requires users to authenticate their identity before viewing them.
  • Backups: Organizations should keep log backups in a secondary location, especially logs needed for audits and regulatory compliance.

Exploring the Need for Security Skills in the DevOps Jobs Market

Exploring the Need for Security Skills in the DevOps Jobs Market

Getting more done in less time is a goal all companies strive for. In the field of software development, DevOps is making this happen. The DevOps methodology has revolutionized software development and deployment by streamlining the relationship between developers and operations teams. Businesses that have adopted DevOps are reaping the benefits of faster software delivery and more stable operating environments, so it is no surprise that DevOps has become one of the highly sought-after career fields.

The DevOps job market shows just how valued DevOps has become. The average salary for DevOps engineer jobs is over $109,039 per year (Glassdoor, 2023). The DevOps market is expected to grow at a 19.7% CAGR during the forecast period, from an estimated USD 10.4 billion in 2023 to USD 25.5 billion in 2028 (MarketsandMarkets, 2023). That is some pretty impressive growth for any career field.

At the same time, integrating security into DevOps jobs has become a higher priority. Since custom applications handle sensitive and proprietary data, possessing security skills is becoming necessary in the DevOps jobs market. If you’ve been thinking about making a career move into DevOps, you should be aware of the increasing importance of security in the DevOps jobs market.

What are the New Skills Employers are Looking For?


DevOps engineer skills have been in demand for quite some time. However, now that the career field has become more established, employers are looking for a broader set of skills. Companies have had years to refine their software deployment processes and are now putting out some very specific DevOps job requirements.

For example, familiarity with Unix and Linux environments is now a common DevOps job requirement. Much of the automation that powers DevOps is accomplished through scripting Linux and other Unix-like operating systems. Tasks such as text processing, system administration, and file handling (i.e., copying and moving files) are handled via scripts. Experience creating, modifying, and scheduling shell scripts will quickly become a requirement for DevOps jobs.

An understanding of the tools and apps commonly found in Linux environments is now a required DevOps engineer skill. Employers are looking for candidates who can work with version control systems like Git, the Apache web server, and containerization tools such as Docker and Kubernetes.

Above every other new skill, though, is the need for strong DevOps security skills. The speed of deployment in the early years of DevOps could lead to security issues getting only minimal attention. Traditional IT security methods are often not a good fit for DevOps environments. Security in DevOps should be automated as much as possible, like much of the rest of DevOps, but there is now less tolerance for unsecured code in deployed software projects.

Employers are now looking for engineers with the ability to build risk-averse and security-compliant apps but at the speed of DevOps. Going forward, this will likely be the top priority among all DevOps engineer skills.

Growing Significance of Security in DevOps Jobs Requirements


This emphasis on security skills in the DevOps jobs market can be directly tied to the increasing threat landscape. In many ways, it’s easier than ever for those with bad intentions to get started with cybercrime. In the past, hackers had to write scripts and craft custom tools to carry out their nefarious work; today, the means to accomplish the same tasks can be freely downloaded if someone is so inclined. While some people may try hacking tools to see what they can do with them and do not have any evil intent, the threat level rises with such a lower barrier to entry.

Ransomware is also rising, representing one of the most severe threats to enterprise application security. As a company’s data is often its most valuable asset, malicious hackers have more motivation to hold digital assets for ransom. And most important to the DevOps market, the window of time to patch vulnerabilities is shrinking. This means it is more important than ever to identify and address security issues and ship an updated version.

In 2023, 22,000 application vulnerabilities were discovered every day (Forbes, 2023). In response, companies looking to bolster their staff with more DevOps jobs are now emphasizing security. Businesses need the speed and flexibility that DevOps brings to their application development lifecycle, but they need DevOps to be more secure and respond to threats faster.

Integration of Security with DevOps Lifecycle


Those who accept new DevOps jobs should change the approach and attitude that has always applied to the DevOps lifecycle. Collaboration between security teams and DevOps professionals must become a part of the lifecycle while maintaining speed and automation.

A higher level of security can be integrated into DevOps by using automated scanning tools. Artificial intelligence tools, such as large language models, that power popular tools like ChatGPT can also be applied to DevOps scanning practices. Code can be scanned as it is written, both by developers’ programming tools and external tools.

Automated scanning can also be applied to the other tools in the DevOps lifecycle. Much of today’s DevOps jobs are built on open-source tools and third-party container images. The programming environments that developers use, particularly on Linux machines, tend to have a lot of external dependencies written by third parties. While these tools and products are typically safe, they present an avenue for malicious code to be injected into the development process. Scanning containers and external code can help neutralize these potential threats.

Continuous improvement and continuous delivery (CI/CD) is one of the foundational concepts in DevOps. However, CI/CD pipelines have traditionally focused on bug fixes. A shift in attitude that CI/CD should also address security issues will be key to integrating security into the DevOps lifecycle. Teams that have accomplished this now often refer to themselves as DevSecOps, reflecting the increased emphasis on security.

How EC-Council’s DevSecOps Certification Helps DevOps Engineers Upgrade Their Security Skills


Cybersecurity professionals can acquire the skills necessary to design, implement, and manage secure applications and infrastructure via the EC-Council Certified DevSecOps Engineer (E|CDE). In the E|CDE course, you’ll learn how the security bottlenecks of DevOps led to the emergence of DevSecOps. You’ll discover how the philosophy and culture of DevSecOps is enhancing collaboration between development and operations teams in today’s DevOps jobs and why that’s essential for the threat landscape of the future.

In the more than 80 labs in the E|CDE, you’ll integrate real-world tools such as Eclipse and GitHub with Jenkins to build applications. At the same time, you will learn how to integrate threat modeling tools like Threat Dragon and ThreatSpec to integrate security into the DevOps process. You gain the skills for DevOps that employers look for today while practicing in popular enterprise cloud environments like AWS and Azure.

What is SQL Injection attack

What is SQL Injection attack

Most of the prominent data breaches that occur today have been the outcomes of an SQL Injection attack, which has led to regulatory penalties and reputational damages. An effective SQL Injection attack can lead to unapproved access to delicate data, including credit card information, PINs, or other private information regarding a customer. In some instances, an attacker can acquire a dogged backdoor into an establishment’s systems, resulting in a continuing breach that can be overlooked for a prolonged timeframe.

What is SQL Injection attack

The moment sensitive data is breached in any cyberattack, it may be hard to ever recover fully. The good news is that both attackers and defenders can use the SQL Injection application. For instance, a company that has been compromised by SQL Injection attacks or vulnerabilities can employ the services of a Certified Ethical Hacker to help them access loopholes using SQL injection attacks.

No company can claim to have completely fortified its security against cyberattacks. This is why the best practice for every business is to begin by identifying the most common types of vulnerabilities and mitigate them to prevent further exploitation and to stop them before they escalate. SQL Injection attacks are itemized on the top 10 lists of application security threats that companies face on the OWASP webpage. Thus, IT professionals, cybersecurity professionals, and cybersecurity enthusiasts need to understand what an SQL Injection is.


We will now explore every detail about an SQL Injection attack to discover what it is based on, how it works, and how an SQL Injection can be tracked and prevented

What Is an SQL Injection Attack?


SQL Injection (SQLi) is a popular attack vector that makes it possible for an attacker to perform malicious SQL statements for backend database manipulation or restrict the queries that an application makes to its database. Attackers take advantage of SQL Injection vulnerabilities to bypass login and other application security procedures. In simple words, SQL Injection permits an attacker to access data that they would normally be unable to recover. This data may comprise a few items, such as private details about a client, sensitive company data, or user lists.

An SQL Injection attack is based on an “injection” or insertion of a SQL query through input data from the customer to the application. SQL Injection is typically recognized as an attack vector for websites; however, it can be exploited to attack any number of SQL databases. The actions of a successful SQL Injection exploit can access delicate information from the database, amend the data from the database (Insert, Modify, and Delete), retrieve the content of a specified file available on the DBMS file system, become administrators of the database server (including shutting down the DBMS), and in some situations, send commands to the operating system.

Simply, a successful SQL attack can be carried out through the following methods:

  • Adjusting or compromising data
  • Exfiltrating or pinching data
  • Sidestepping authentication
  • Changing database permissions
  • Removing data
  • Running arbitrary code

Based on Akamai’s report, it was demonstrated that SQL Injection currently represents about 65.1 percent (almost two-thirds) of all web application attacks. This is 44 percent above the web application layer attacks represented by SQLi in 2017. Many web applications have SQL Injection vulnerabilities, indicate the fairly limited attention given to the security application development phase.

Why Do Hackers Use SQL Injection?


Hackers use SQL Injection to attempt to enter a precisely created SQL commands into a form field rather than the predictable information. The reason for this is to secure a response from the database that will enable the hacker to recognize the construction of the database, including table names. If the SQL Injection attack is finalized successfully, it has the possibility of being extremely damaging to any individual or business.

SQL Injection is incredibly popular with ASP and PHP applications based on the pervasiveness of outmoded functional interfaces. Owing to the characteristics of existing programmatic interfaces, ASP.NET, and J2EE applications are often unlikely to have effortlessly exploited SQL Injections. The detrimental impacts of SQL Injection attacks can be very severe. This severity is restricted by the skill and imagination of the hacker, and to some degree, defense-in-depth countermeasures, including short privilege link to the database server.

How Does SQL Injection Work?


SQL is a query language intended to run data kept in functional databases. SQL queries are implemented to perform commands, like updates, data retrieval, and deletion of records. Diverse SQL essentials execute these tasks. Examples include, queries using the SELECT statement to recover data through user-offered strictures.

For an SQL Injection attack to be executed, the hacker must first discover defenseless user inputs in the web application or web page. SQL Injection is then exploited by unscrupulous hackers to locate the IDs of other users within the database, and these users are then impersonated by the attacker. The impersonated users are often people with data privileges such as the database administrator.

The web application or web page with an SQL Injection vulnerability exploits the user’s input openly in an SQL query and generate input content. This type of content is usually referred to as a “malicious payload,” and it represents the most significant aspect of the attack. The malicious SQL commands are performed in the database once the malicious hacker sends this content.

Since SQL makes it possible for you to choose and output data from the database, an SQL Injection vulnerability may permit the attacker to have full access to the entire data within a database server. SQL is designed in such a way that it allows you to modify or change the data in a database and insert new ones. An attacker can use SQL Injection in a financial application to make some transactions void, change balances, or move money from the user’s account to another account.

What Is SQL Injection Example?


There are several SQL Injection attacks, Vulnerabilities, and procedures that occur in diverse circumstances. An attacker that wants to perform an SQL Injection exploits a standard SQL query to manipulate unauthorized data Vulnerabilities in a database. This attack vector can be executed in several ways. However, a few of the common SQL Injection examples include the following:

  • Retrieving hidden data: This occurs by modifying an SQL query to recover further outcomes.
  • UNION attacks: Here, the attacker recovers data from diverse database tables.
  • Subverting application logic: Here, the attacker modifies a query to compromise the application’s logic.
  • Blind SQL Injection: In this situation, the results of a query a user controls do not return in the application’s responses.
  • Examining the database: Here, you can remove the information regarding the structure and version of the database.

Furthermore, let’s consider two database tables for this SQL Injection example, that is, Users and Contacts. The User table does not necessarily have to be extremely technical; it can be as simple as entering just three fields. This field would include the User ID, username, and password. However, the Contacts table would require more information concerning the users, including the User ID, First Name, Last Name, First Address, Email, security code, and credit card information. So, the Users table would have the login information below: 

  • wsmith,JusticeIsHere!
  • jsparks,Pow3rPassword$Secur3ed
  • kperry,P@$$w0rd

A solid password must be primed and hashed when placed in a database. Avoid using cleartext to avoid being compromised. When you want to log in, you would have to enter your username and passwords in the login page. The information you enter is sent to the website’s server, which constructs a SQL query and that query is sent to the database server. This is what the query would look like:  

Select ID from Users where username=’kperry’ and password=’P@$$w0rd’

How SQL work is that each of the rows the query requests is assessed based on a true or false comparison. Using the above example as a guide, the query suggests that, for every row where the username is kperry and the password is P@$$w0rd, we check the Users table and give back the ID value. Usually, the web site’s server realizes what is sent back via the database server. With our example, the website’s server would get a ‘1’ and allow the user to go past the login page. 

However, if we want to get malicious with the query, we will have to trick the server into believing that we have authentication, considering that the database server executes a true-or-false check. This can be achieved by including an OR to our password. If we login with x’ or a=a as our password, a new SQL query would be created: 

Select ID from Users where username=’kperry’ and password=’x’ or a=a

We would successfully bypass being kicked off because even though x is not kperry’s password, the database server will automatically verify the second option. It will check the alternative if x is not kperry’s password, is an equal a? Since it does, the ID will be returned to the application, and the user will have a successful authentication. Moreover, the situation does not necessarily have to be an a=a situation. Once the two values are equal, then this command would work. You can have b=b, 1=1, or even 2452=2452. 

If the webpage can display data, it might be able to print other data to the screen. To obtain the data, you can try chaining two SQL requests together. Furthermore, we can add a second statement to our ‘ or a=a, such as UNION SELECT LastName, security code from Contacts, and credit card details. Additional clauses such as this might require more input. Nevertheless, gaining access to data is the final objective of an SQL Injection attack.

Another procedure can be adapted for blind SQL Injection, the technique where no data is returned to the screen to inject other hints. Comparable to our ‘ or a=a situation, we can command the server to take a nap. We could include: “ ‘ or nap(20) ” and this executes what it appears to be. This commands the database server to snooze for 20-seconds, while other responses are deferred.

What are the Types of SQL Injection?


SQL Injection types exist in different categories; however, they are all concerned with an attacker introducing random SQL into a web page or web application database query. The easiest method of SQL Injection is via user input. Typically, web apps receive user input using a form. So, the front end sends the user input to the back-end database for processing.

In-band SQLi

In-band SQL Injection happens when an unscrupulous hacker can effectively apply the same communication channel for introducing an attack and collating the results. Attackers exploit the same channel of communication to introduce their attacks and to assemble their outcomes. In-band SQL Injection is one of the simplest and most popular SQL Injection attacks, making it easy to exploit. The two popularly known sub-categories of in-band SQL Injection include:

Error-based SQLi

This is an in-band SQL Injection practice where an attacker executes actions that lead to error messages. These error messages are cast by the database server to gain data regarding the structure of the database. Although errors are extremely valuable during the development stage of a web application, these should be logged to a file with limited access or deactivated on a live site.

Union-based SQLi

Union-based SQL Injection technique takes advantage of the UNION SQL operator to merge the results of multiple SELECT statements to get a single result that is afterward sent back as part of the HTTP response. This attacker leverages the data from this response.

Out-of-band SQLi

Unlike the in-band SQLi technique, the out-of-band SQLi technique is not as popular. The reason is that an attacker can only perform this type of attack when specified features are activated on the database server engaged by the web page. This type of attack is mostly used when an attacker is unable to use the same channel to introduce the attack and assemble results.

It is an alternative to the Blind and in-band SQLi practices, particularly when the server responses are less steady. Out-of-band SQLi procedures matter based on the capability of the server to generate HTTP or DNS requests to transmit data back to an attacker

Blind or Inferential SQLi

Most situations of an SQL Injection attack are blind vulnerabilities. This is because applications do not send back SQL query results or the particulars of database errors within its responses. As an alternative, an attacker who can reconstruct the structure of the database by transmitting payloads monitors the response of the web application and the ensuing performances of the database server. This is often more complicated and difficult for an attacker to exploit, but it is as dangerous as any other form of SQL Injection available. Inferential or blind SQLi can be grouped into two sub–categories:

Time-Based

Using this blind technique, the attacker transfers a SQL query to the database, making the database hold for some seconds before responding. Time-based SQLi depends on transferring an SQL query to the database, which in turn influences the database to halt for a short period, usually in seconds, before it can react. The attacker can observe from the response time whether the ensuing query is true or false.

Depending on the result, an HTTP response is created immediately or after a delay. The attacker can, therefore, understand if the message they applied returned true or false, without depending on the data from the database. This type of attack is often time-consuming, particularly when large databases are involved because a requirement for an attacker is that they should itemize the database character by character. 

Boolean or Content-based

This blind SQLi technique is used by an attacker to send a SQL query to the database, forcing the application to generate a result. Depending on whether the query is true or false, varying results would be generated. Also, depending on the returned result, the content within the HTTP response is altered or remains unaffected. Afterward, the attacker can determine whether the message created is a true or false result.

Can SQL Injection be traced?


Most SQL Injection Vulnerabilities and attacks can be reliably and swiftly traced through a number of credible SQL Injection tools or some web vulnerability scanner. SQL Injection detection is not such a trying task, but most developers make errors. Due to this, SQLi detection is extremely significant for mitigating and reducing the damaging effect of SQLi Vulnerabilities.

To detect and remove the primary form of SQLi attacks, you would have to install a web application firewall (WAF). You need to make sure that the WAF isn’t the only defensive measure you have in place to tackle the SQL Injection attack. Together with your WAF, you can fortify your systems with network-based and host-based Intrusion Detection Systems (IDS).

Likewise, SQL Injection can be manually traced using a methodical set of assessments against every entry point in the application. This typically involves:

  • Presenting Boolean conditions, including OR 1=1 and OR 1=2, and searching for variances in the application’s responses.
  • Presenting OAST payloads intended to prompt an out-of-band network interface when performed within an SQL query, and checking for any ensuing exchanges.
  • Presenting certain SQL-precise syntax that assesses to the base (initial) value of the entry point, and a changed value, and searching for systematic variances in the ensuing application responses.
  • Presenting the distinct quote character ‘ and searching for faults or other irregularities.
  • Presenting payloads intended to activate time delays when performed within an SQL query, and searching for alterations in the time taken to respond.

How can SQL Injection be prevented?


SQL Injection attack can be prevented by adopting the OWASP SQL Injection Cheat Sheet. You cannot determine whether the SQL query string is distorted with a server-side scripting language. This can only send a string to the database server and hold on for the deciphered response.  

As an expert ethical hacker, it is recommended that you apply different solutions and prepared statements with whitelisting input validation, escaping, validation, and bind variables. There are different ways to sanitize user input. Precise prevention practices are based on the sub–category of the SQLi vulnerability, the programming language, and the SQL database engine. However, the only guaranteed approach for preventing SQL Injection attacks is to use input validation and parameterized queries, such as prepared statements.

How to Recover from an SQL Injection Attack?


There are different strategies for recovering deleted and damaged data during an SQL attack. Data recovery is a significant part of an incidence response process that must be implemented by organizations whose data or a security system has been compromised. The incidence response team (IRT) can use one of two options, either a log shipped database, which identifies and corrects the data, or you can apply a disaster recovery solution, which focuses on data retrieval through backups. However, both strategies are not fail-safe. You would need a skilled or certified incident responder to select the appropriate approach. The cons and pros of these approaches are explained below:

01. Using Data Correction Analysis

The advantage of using this approach is that, if you know the precise time when the data was compromised and if you have a technology or product that can get you back online, you can easily and quickly recover the data within a short period. However, if you are uncertain about the exact time your data was infected, it would be difficult for you to make a quick recovery, leading to an enormous data loss. Furthermore, making a quick recovery from a backup could be compulsory in this case, since data are often added and not repositioned, introduced, or removed. Thus, eliminating the malicious string is all that is required.  

02. Using Backup/Restore or High Availability Option Analysis

It is simple to find and replace values in all text columns and all tables scripts for the SQL server, so the malicious content can be traced and corrected by a certified incident responder. Thus, through this data correction analysis, the incident responder or IRT can easily detect and correct the table values. However, the con for this analysis is that you are required to perform a database backup before making any alterations or to preserve the information for forensic reasons. Consequently, you need to ensure that the SQLi technique follows the required recommendation if you are to get the appropriate response.

Organizations face an ever-changing digital landscape, which often results in new security risks. Cyberthreats continue to plague both governments and businesses around the world, highlighting the need for security professionals and leaders who can supply the skills and leadership to combat them.

As the world of information security evolves, so must the skills of those tasked with protecting online data and other digital assets. Chief information security officers (CISOs), who play a vital role in information security management, must possess a unique blend of leadership strength and technical ability.

CISOs must stay up to date with the latest trends and technologies to effectively handle security risks and incidents—a daunting task in light of the fast-moving tech landscape. To add to the challenge, many CISOs are also responsible for managing multiple teams and large security budgets.

Given that attack vectors and tactics are becoming increasingly sophisticated, information security leaders must ensure that they have the necessary skills to confront these challenges.

The following infographic sheds light on four core competencies for CISOs

Essential Information Security Management Skills CISOS

Core Skills for Today’s CISOs


CISOs must have a strong understanding of the security threats relevant to their industry and be able to work collaboratively with other teams. Let’s take a closer look at four information security management skills that are essential for CISOs in today’s businesses.

01. Develop and Execute Organizational Security Plans


As businesses rely on their data and networks to sustain their operations, protecting against cybercrime is a prime concern for many organizations. Cybercriminals are constantly looking for loopholes to gain access to sensitive information, and the consequences of a data breach can be huge, affecting an organization’s financial standing and reputation.

A sound security strategy is indispensable in protecting an organization against hacking, intrusion, and data theft. CISOs play a critical role in creating this strategy. A CISO is tasked with regularly assessing an organization’s security posture, helping to ensure that the organization is prepared to counter any threats that could appear. This is a significant undertaking, as security posture encompasses the overall security status of an entire company’s networks, software, and hardware. CISOs play a significant role in designing and implementing an organization’s security strategy, considering all aspects of data security. This includes creating security policies to minimize potential threats and vulnerabilities, coordinating compliance and certification requirements, managing security teams, and overseeing various security-related initiatives.

Security policies should include definitions of roles, responsibilities, and standards with corresponding accountability. It should describe the duties of various individuals and groups who would be involved in the response to a security incident, such as network administrators, security officers, and auditors. A security policy should also identify approved data handling and dissemination procedures and provide a means for periodic review of these procedures. A security policy is a guide that an organization follows to keep its information assets safe from internal and external threats. For example, a security policy could specify that all data on portable computing devices must be encrypted, including the levels of encryption that must be used, how they are to be applied, and the devices affected (e.g., all laptops, hard drives, mobile devices, and any storage devices connected to the organization’s computers).

02. Identify and Control Points of Vulnerability


CISOs ensure real-time monitoring for cybersecurity threats. To prevent costly data breaches, they identify and control vulnerable access points in the organization’s IT architecture, such as databases and firewalls. These actions are especially important for systems that hold sensitive or proprietary information, as even a single breach can have devastating consequences.

Most CISOs start their day by reviewing important security-related news and any internal situation or incident reports. This keeps them aware of new or emerging cyber risks, which in turn helps them identify potential areas of concern that may require additional investigation. Experienced security leaders understand that it is not possible to eliminate all risks associated with a particular program or task or completely protect all systems and data. The CISO’s goal is instead to identify the most damaging risks and vulnerabilities and implement a set of controls or countermeasures that will provide a reasonable level of assurance that the organization’s security is adequate.

03. Manage IT Audits and Establish Security Performance Metrics


CISOs also supervise IT audits that provide valuable insights into their organization’s cybersecurity posture. By bringing together various experts—including cybersecurity professionals—audit teams led by information security leaders can offer an objective view of an organization’s risks and how they compare to others in the same industry segment.

The goal of the audit committee is to understand cyber-risk exposure and information security management across all lines of business. The audit committee can only get this information from information security leaders like CISOs, as they are responsible for overseeing all cyber-risk management functions within the company. CISOs are also responsible for developing a cohesive security performance measurement system for cybersecurity monitoring. CISOs need to understand—and sometimes decide—how their organization defines security effectiveness and uses the chosen metrics in its security program. CISOs must know the difference between effectiveness and efficiency and use the appropriate metrics to measure each.

Example Measures of Effectiveness*   Example Measures of Efficiency* 
Number of security policies properly documented and in use

Percentage of security incidents reported within required timeframe

Percentage of security vulnerabilities that have been patched
  Percentage of discovered vulnerabilities mitigated within target timeframe

Frequency of audit reviews and analyses

Percentage of system components that undergo maintenance on schedule 

04. Strategically Plan the Enterprise Information Security Architecture


CISOs are responsible for maintaining the safety of their organization’s data and ensuring that the allocated budget for cybersecurity is used efficiently and effectively. A good CISO ensures that the money their organization spends on cybersecurity is allocated wisely by making smart decisions about where to invest in cybersecurity.

Thus, CISOs need to have good business acumen as well as a strong technical background. Since every business faces different risks and has a different appetite for risk, a CISO must understand their specific organization and its operations. This is especially true for organizations that must operate under special conditions, such as industry-specific regulatory compliance mandates.

Understanding the various applicable risks and how their organization operates enables CISOs to create a cybersecurity strategy that meets their organization’s specific needs. The CISO should also work with various stakeholders to secure the necessary financial resources and develop partnerships with third-party vendors and security professionals.
