A false positive is a condition in which harmless traffic is classified as a potential network attack by a NIDS. A NIDS is a network intrusion detection system that monitors network traffic for any signs of malicious or anomalous activity. A false positive can result in unnecessary alerts or actions by the NIDS, such as blocking legitimate traffic or generating false alarms. False positives can be caused by various factors, such as misconfigured rules, outdated signatures, noisy network traffic or benign anomalies3 .

System timeline reconstruction is a forensic analysis technique that involves creating a chronological record of events that occurred on a system based on various sources of evidence such as log files, registry entries, file timestamps, network traffic, etc. System timeline reconstruction can provide information about when and how the machine was compromised and where the malware is located by showing when suspicious activities or changes took place on the system, such as unauthorized access attempts, file creation or modification, process execution, network connections, etc.

Static analysis is a method of analyzing software code without executing it, by using tools or techniques that check for syntax errors, logic errors, vulnerabilities, coding standards, and other quality issues. Static analysis can help software developers to correct the error-handling capabilities of an application before pushing it to production, as it can detect potential errors and bugs at an early stage of development. A web-application vulnerability scan (A) is a method of testing web applications for security flaws by simulating attacks and analyzing responses. It can be useful for finding vulnerabilities in web applications, but not for validating the error-handling capabilities of an application. A packet inspection © is a method of monitoring network traffic by examining the data packets that are sent and received over a network. It can be useful for detecting malicious or unauthorized activity on a network, but not for validating the error-handling capabilities of an application. A penetration test (D) is a method of evaluating the security of a system or network by simulating real-world attacks and exploiting vulnerabilities. It can be useful for assessing the overall security posture of a system or network, but not for validating the error-handling capabilities of an application.

The correct answer is C. Corrective. A corrective control is a type of control that is used to restore normal operations after a security incident or event has occurred. A corrective control can include actions such as restoring a backup, applying patches, reconfiguring settings, or replacing damaged components. A corrective control can help to mitigate the impact of an incident and prevent further damage or loss1.

A. Technical is not correct. A technical control is a type of control that is implemented using hardware, software, or firmware to protect the confidentiality, integrity, and availability of information and systems. A technical control can include mechanisms such as encryption, authentication, firewalls, antivirus, or intrusion detection systems. A technical control can be preventive, detective, or responsive, depending on its function2.

B. Responsive is not correct. A responsive control is a type of control that is used to react to a security incident or event in real time and stop or contain the attack. A responsive control can include actions such as blocking traffic, isolating systems, terminating processes, or alerting users. A responsive control can help to reduce the severity and duration of an incident and limit its spread3.

D. Preventive is not correct. A preventive control is a type of control that is used to deter or avoid a security incident or event from happening in the first place. A preventive control can include measures such as policies, procedures, training, awareness, or physical security. A preventive control can help to reduce the likelihood and frequency of an incident and minimize its potential impact.

The analyst decided to include a custom lookup for these files on the endpoint’s log-in script as a mechanism to improve existing detection capabilities, by checking if any of these files are present on the endpoints during log-in. This can help identify any compromised endpoints that may have been infected by the zero-day vulnerability, and alert the analyst for further investigation or response.

A hacktivist is a type of actor who uses hacking techniques to promote a political or social cause or agenda. Hacktivists often target websites or systems of organizations or governments that they oppose or disagree with, and deface them with messages or propaganda related to their cause. In this case, the hacktivist defaced the corporate websites with political propaganda.

SSO stands for Single Sign-On, and it is a technology that allows users to authenticate once and access multiple applications or systems without entering their credentials again. SSO can help streamline each employee’s authentication, by reducing the number of passwords they have to remember or enter, and improving their user experience and productivity.

 Consumer IoT devices are devices that connect to the internet and provide various functions or services for personal or home use, such as smart speakers, cameras, thermostats, etc. Consumer IoT devices should be avoided in an enterprise environment because they may pose security risks or challenges for the organization’s network and data. Some of the reasons why consumer IoT devices should be avoided are:

The devices may have weak or known passwords: Many consumer IoT devices come with default or hardcoded passwords that are easy to guess or find online. Some devices may not allow users to change their passwords or enforce strong password policies. This can make them vulnerable to brute-force attacks or unauthorized access by attackers.

The devices may utilize unsecure network protocols: Many consumer IoT devices use unsecure network protocols to communicate with other devices or servers, such as HTTP, FTP, Telnet, etc. These protocols do not encrypt or authenticate the data they transmit or receive, which can expose them to interception, modification, or spoofing by attackers.

Validating user input before execution and interpretation can help to prevent dynamic code evaluation script injection vulnerabilities by checking and filtering any malicious input from the user that may contain code or commands. Dynamic code evaluation script injection is a type of vulnerability that occurs when an application accepts user input and executes or interprets it as part of its own code without proper validation or sanitization. This can allow an attacker to inject arbitrary code or commands into the application and execute them with the same privileges as the application . Validating user input before execution and interpretation can help to ensure that the input conforms to the expected format, length and type, and does not contain any malicious characters or syntax that may alter the logic or behavior of the application .

The analyst should disclose details regarding the findings of the vendor’s latest penetration test summary as the first recommendation, as this can help assess the vendor’s security posture and identify any potential risks or issues that may affect the organization. The analyst should review the findings and ask for more information about the scope, methodology, and remediation actions of the penetration test, as well as any evidence or artifacts that support the findings.
