Explanation:
Explanation
The CySA+ exam outline calls out "trusted firmware updates," but trusted firmware itself is more commonly described as part of trusted execution environments (TEEs). Trusted firmware is signed by a chip vendor or other trusted party, and then used to access keys to help control access to hardware. TEEs like those used by ARM processors leverage these technologies to protect the hardware by preventing unsigned code from using privileged features."

NEW QUESTION # 53
A security manager has asked an analyst to provide feedback on the results of a penetration test. After reviewing the results, the manager requests information regarding the possible exploitation of vulnerabilities. Which of the following information data points would be MOST useful for the analyst to provide to the security manager, who would then communicate the risk factors to the senior management team? (Select TWO).
- A. Impact
- B. Adversary capability
- C. Indicators of compromise
- D. Probability
- E. Classification
- F. Attack vector
Answer: A,B
Explanation:
Explanation
According to the CompTIA CySA+ (CS0-002) best practices, the most useful information data points to provide to the security manager for communicating the risk factors to senior management are the impact and adversary capability. The impact refers to the potential consequences of a successful attack or exploitation of a vulnerability, such as data loss or system compromise. The adversary capability refers to the ability of an attacker to exploit a vulnerability, including their technical expertise and resources. Together, these data points help to provide a complete picture of the risk associated with a vulnerability, and allow senior management to make informed decisions regarding risk mitigation and remediation. The other data points, such as probability, attack vector, classification, and indicators of compromise, can also be valuable, but the impact and adversary capability are considered the most critical for prioritizing risk mitigation efforts.
