Show Suggested Answer Hide Answer
Suggested Answer: D

A Web Application Firewall (WAF) is the best solution to implement for a public cloud IaaS hosted customer relationship management application vulnerable to remote command execution attacks. WAFs are designed to monitor, filter, and block malicious HTTP/S traffic to and from a web application to protect against various application layer attacks, including remote command execution.

I lean towards WAF as the best option since it specifically targets web application attacks, but I need to double-check my notes on that.

ACLs seem like they could limit access, but I doubt they would directly prevent exploitation of that vulnerability.

I practiced a similar question where an IPS was the answer, but I feel like that might not be enough for remote command execution.

I think I remember that a WAF could help filter out malicious requests, but I'm not entirely sure if it's the best choice here.
