質問 # 267
An analyst needs to provide recommendations based on a recent vulnerability scan:
Which of the following should the analyst recommend addressing to ensure potential vulnerabilities are identified?
正解：B
解説：
This is because scanning without admin privileges can limit the scope and accuracy of the vulnerability scan, and potentially miss some critical vulnerabilities that require higher privileges to detect. According to the OWASP Vulnerability Management Guide1, "scanning without administrative privileges will result in a large number of false negatives and an incomplete scan". Therefore, the analyst should recommend addressing this issue to ensure potential vulnerabilities are identified.
質問 # 268
A company is deploying new vulnerability scanning software to assess its systems. The current network is highly segmented, and the networking team wants to minimize the number of unique firewall rules. Which of the following scanning techniques would be most efficient to achieve the objective?
正解：B
解説：
USB ports are a common attack vector that can be used to deliver malware, steal data, or compromise systems. The first step to mitigate this vulnerability is to check the configurations of the company assets and disable or restrict the USB ports if possible. This will prevent unauthorized devices from being connected and reduce the attack surface. The other options are also important, but they are not the first priority in this scenario.

質問 # 270
An incident response team is working with law enforcement to investigate an active web server compromise.
The decision has been made to keep the server running and to implement compensating controls for a period of time. The web service must be accessible from the internet via the reverse proxy and must connect to a database server. Which of the following compensating controls will help contain the adversary while meeting the other requirements? (Select two).
正解：A、E
解説：
Explanation
Deploying EDR on the web server and the database server to reduce the adversaries capabilities and using micro segmentation to restrict connectivity to/from the web and database servers are two compensating controls that will help contain the adversary while meeting the other requirements. A compensating control is a security measure that is implemented to mitigate the risk of a vulnerability or an attack when the primary control is not feasible or effective. EDR stands for Endpoint Detection and Response, which is a tool that monitors endpoints for malicious activity and provides automated or manual response capabilities. EDR can help contain the adversary by detecting and blocking their actions, such as data exfiltration, lateral movement, privilege escalation, or command execution. Micro segmentation is a technique that divides a network into smaller segments based on policies and rules, and applies granular access controls to each segment. Micro segmentation can help contain the adversary by isolating the web and database servers from other parts of the network, and limiting the traffic that can flow between them. Official References:

質問 # 271
An analyst reviews the following web server log entries:
%2E%2E/%2E%2E/%2ES2E/%2E%2E/%2E%2E/%2E%2E/etc/passwd
No attacks or malicious attempts have been discovered. Which of the following most likely describes what took place?
正解：A
解説：
Directory traversal, also known as path traversal, is an attack that allows attackers to access restricted directories and execute commands outside the web server's root directory. The %2E encoding corresponds to a dot (.) in ASCII, and %2E%2E resolves to ../. The log entries indicate attempts to navigate directories upward to access sensitive files like /etc/passwd. Since no malicious activity was flagged, it is inferred this was either an unsuccessful or reconnaissance attempt.
