CompTIA Exam CAS-004 Topic 1 Question 53 Discussion

Actual exam question for CompTIA's CAS-004 exam
Question #: 53
Topic #: 1
[All CAS-004 Questions]

A security engineer is assessing a legacy server and needs to determine if FTP is running and on which port The service cannot be turned off, as it would impact a critical application's ability to function. Which of the following commands would provide the information necessary to create a firewall rule to prevent that service from being exploited?

Show Suggested Answer Hide Answer
Suggested Answer: C

The netstat -tulpn command is used to display network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. The -tulpn options specifically show TCP and UDP connections with the process ID and the name that is listening on each port, which would provide the necessary information to identify if FTP is running and on which port without turning the service off. This information can then be used to create a precise firewall rule to prevent the FTP service from being exploited.

I agree with Edna, option C seems like the best choice for determining the port number for FTP.

Hey, guys, I've got a great idea! Why don't we just unplug the server and see what happens? That'll definitely solve the FTP problem, am I right? Or maybe we could just throw it out the window, that might work too.

That makes sense, but I still think option C is more relevant for identifying the port FTP is running on.

I disagree, I believe the correct answer is D) systeactl list-unit-file --type service ftpd as it lists all the systemd unit files for the service.

Whoa, whoa, whoa, hold up. Did you guys seriously just suggest 'neestat'? I think you need to lay off the caffeine, my friends. Option D is the way to go, no doubt about it.

Yeah, 'neestat' doesn't sound right at all. Option D is the correct command to use.

Hmm, I'm not so sure. Isn't neestat something you do when you're feeling a little under the weather? I think I'll go with option A, just to be safe.

neestat is not for when you're sick, it's a command for network statistics.
