CompTIA Exam CAS-004 Topic 10 Question 47 Discussion

Actual exam question for CompTIA's CAS-004 exam
Question #: 47
Topic #: 10
[All CAS-004 Questions]

A SOC analyst received an alert about a potential compromise and is reviewing the following SIEM logs:

Which of the following is the most appropriate action for the SOC analyst to recommend?

Show Suggested Answer Hide Answer
Suggested Answer: B

The SIEM logs indicate suspicious behavior that could be a sign of a compromise, such as the launching of cmd.exe after Outlook.exe, which is atypical user behavior and could indicate that a machine has been compromised to perform lateral movement within the network. Isolating laptop314 from the network would contain the threat and prevent any potential spread to other systems while further investigation takes place.

I don't know, guys. Alerting the user seems like a reasonable first step. They might be able to provide more context or even help us identify the source of the issue.

Hold up, what about creating those HIPS and NIPS rules? Seems like a pretty proactive move to me. I mean, if we can shut down those login attempts before they even happen, that's gotta be the way to go, right?

Haha, yeah, like that IT guy who once tried to 'fix' a virus by just unplugging the whole office. That worked out really well, I'm sure.

Nah, I'm not feeling the 'alert JDoe' option. What if the dude's in on it? Then he'll just change his password and keep doing his thing. I say we go for the disable account and isolate laptop combo - cover all our bases, you know?

Yeah, I agree. We should probably start with the least intrusive option and see where that takes us. No need to go full-on security lockdown mode just yet.

Personally, I think the best move is to alert JDoe about the potential compromise. I mean, the guy's account is involved, he should know what's going on, right? Plus, it might help us figure out what the heck is happening on that laptop.

Hmm, this is a tough call. I'd be tempted to go with isolating the laptop, you know, just to be on the safe side. But then again, that might tip off the bad guys and they could try something even sneakier. Decisions, decisions...

Whoa, looks like we've got a real tricky one here! I mean, disabling the account, isolating the laptop, warning the user - it's like a choose your own adventure game, but with cybersecurity stakes!
