The regex pattern /\\w*((\%27)|(\’))((\%6F)|o|(\%4F))((\%72)|r|(\%52))/ix is designed to detect SQL injection attacks. The pattern looks for common SQL injection payloads which typically include an apostrophe or single quote character (' or %27 when URL-encoded) followed by a logical operator OR (represented by o, %6F, O, %4F, r, %72, R, %52). SQL injection attacks involve inserting or “injecting” a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system, and in some cases, issue commands to the operating system.

References: The explanation provided is based on standard practices of monitoring and analyzing IIS logs for security threats. Information about the regex pattern used for detecting SQL injection attacks can be found in various cybersecurity resources, including OWASP’s guide on Testing for SQL Injection1 and Microsoft’s documentation on IIS logging2. These resources explain how regex patterns are used to identify potential security threats in log files and the importance of monitoring logs for unusual patterns that may indicate an attack.

In a Risk Matrix, risk levels are determined by the intersection of the likelihood of an occurrence (probability) and the consequence of that occurrence (impact). When the probability of an event is very high and the impact is major, it typically falls into the ‘Extreme’ category. This is because the combination of a high likelihood and major impact represents a scenario where the risk is unacceptable and requires immediate attention and mitigation measures.

References: The EC-Council’s Certified SOC Analyst (CSA) course materials and study guides provide detailed information on assessing risks using a Risk Matrix. The course emphasizes the importance of understanding the Risk Matrix for effective security operations center (SOC) analysis. For more in-depth information, refer to the official EC-Council CSA study materials and resources12.

A SOC Analyst would use Netstat Data to monitor connections to insecure ports. Netstat, which stands for network statistics, is a command-line tool that displays incoming and outgoing network connections (both TCP and UDP), routing tables, and a number of network interface and network protocol statistics. It is available on various operating systems, including Windows, Linux, and Unix, and is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement.

References: The use of Netstat for monitoring network connections is a common practice and is covered in EC-Council’s SOC Analyst curriculum, which provides foundational knowledge for security operations center (SOC) team members on various tools and techniques for monitoring and analyzing network traffic12. Additionally, Netstat’s capabilities are well-documented in various technical resources that detail its usage for security analysis purposes34.
