Show answer and explanation
Correct answer: A
Explanation
The correct action to mitigate the described threat is to apply the latest security patches to the operating system. This addresses the vulnerability being exploited by the attacker and prevents further unauthorized access. While other options may be part of a broader security plan, they do not directly resolve the specific issue caused by the outdated OS.
- A. Correct.
Applying the latest security patches resolves the vulnerability being exploited by the attacker, effectively mitigating the threat.
- B. Incorrect.
Installing an IPS is a preventative measure, but it does not directly address the vulnerability in the outdated operating system.
- C. Incorrect.
Enabling port mirroring helps monitor network traffic but does not mitigate the vulnerability or stop the exploit.
- D. Incorrect.
Performing a backup and replacing servers is a drastic measure that does not address the root cause of the vulnerability or stop the exploit.
