Question 1

A list of loCs released by a government security organization contains the SHA-256 hash for a Microsoft-signed legitimate binary, svchost. exe. Which of the following best describes the result if security teams add this indicator to their detection signatures?

Answer : A

Adding the SHA-256 hash of a legitimate Microsoft-signed binary like svchost.exe to detection signatures would result in the indicator firing on the majority of Windows devices. Svchost.exe is a common and legitimate system process used by Windows, and using its hash as an indicator of compromise (IOC) would generate numerous false positives, as it would match the legitimate instances of svchost.exe running on all Windows systems.

Question 2

The Chief Information Security Officer (CISO) of a large management firm has selected a cybersecurity framework that will help the organization demonstrate its investment in tools and systems to protect its dat

a. Which of the following did the CISO most likely select?

Answer : C

Question 3

A SOC analyst determined that a significant number of the reported alarms could be closed after removing the duplicates. Which of the following could help the analyst reduce the number of alarms with the least effort?

Answer : A

Security Orchestration, Automation, and Response (SOAR) can help the SOC analyst reduce the number of alarms by automating the process of removing duplicates and managing security alerts more efficiently. SOAR platforms enable security teams to define, prioritize, and standardize response procedures, which helps in reducing the workload and improving the overall efficiency of incident response by handling repetitive and low-level tasks automatically.

Question 4

A company is launching a new application in its internal network, where internal customers can communicate with the service desk. The security team needs to ensure the application will be able to handle unexpected strings with anomalous formats without crashing. Which of the following processes is the most applicable for testing the application to find how it would behave in such a situation?

Answer : A

Fuzzing is a process used to test applications by inputting unexpected or random data to see how the application behaves. This method is particularly effective in identifying vulnerabilities such as buffer overflows, input validation errors, and other anomalies that could cause the application to crash or behave unexpectedly. By using fuzzing, the security team can ensure the new application is robust and capable of handling unexpected strings with anomalous formats without crashing.

Question 5

A healthcare organization must develop an action plan based on the findings from a risk

assessment. The action plan must consist of:

* Risk categorization

* Risk prioritization

. Implementation of controls


Click on the audit report, risk matrix, and SLA expectations documents to review their


On the Risk categorization tab, determine the order in which the findings must be

prioritized for remediation according to the risk rating score. Then, assign a categorization to each risk.

On the Controls tab, select the appropriate control(s) to implement for each risk finding.

Findings may have more than one control implemented. Some controls may be used

more than once or not at all.
