GIAC GSNA Exam - Topic 6 Question 43 Discussion

Actual exam question for GIAC's GSNA exam

Question #: 43
Topic #: 6

You work as the Network Administrator for McNeil Inc. The company has a Unix-based network. You want to track the system for user logins. To accomplish the task, you need to analyze the log configuration files. Which of the following Unix log configuration files can you use to

accomplish the task?

A/var/log/messages

B/var/log/secure

C/var/spool/mail

D/var/log/maillog

Show Suggested Answer

Suggested Answer: C

A null session is an anonymous connection to a freely accessible network share called IPC$ on Windows-based servers. It allows immediate

read and write access with Windows NT/2000 and read-access with Windows XP and 2003.

The command to be inserted at the DOS-prompt is as follows:

net use \IP address_or_host nameipc$ '' '/user:'

net use

Port numbers 139 TCP and 445 UDP can be used to start a NULL session attack.

No way /var/log/maillog is relevant for user logins.

Surprised that /var/spool/mail is even listed here!

Wait, isn't /var/log/messages also useful for this?

I'm a bit confused about /var/spool/mail; I don't think it relates to user logins, but I can't remember what it's specifically for.

I practiced a similar question where we had to identify log files, and I think /var/log/secure was the answer there too.

I think /var/log/secure is definitely the right choice for tracking logins, but I also recall something about /var/log/messages being useful for general system logs.

I remember that user logins are usually tracked in the secure log, but I'm not entirely sure if that's the only one we need to check.

This is a good question to test our knowledge of Unix log files. I think the key is to focus on the files that are most likely to contain user login information. /var/log/secure seems like the best bet based on that criteria.

Okay, let's see. I know the /var/log/messages file is a general system log, and /var/log/secure is often used for security-related events. I'm guessing one of those two is the right answer here.

This seems like a straightforward question about Unix log files. I'm pretty confident I can find the right answer by thinking through the typical log files used for user login tracking.

Hmm, I'm a bit unsure about this one. I know there are a few different log files in Unix, but I'm not sure which one would specifically track user logins. I'll have to think this through carefully.

Okay, let's see. We need to configure the retention for backups from an on-premises server to Azure. That sounds like it would be done through the Recovery Services vault, which is the central management point for Azure Backup. I'm pretty confident that's the right answer.

This question seems pretty straightforward. I think I can just compare the time it takes to scale up 500 nodes in the different modes and select the correct answer.

Hah, /var/spool/mail? That's where the actual emails are stored, not the login logs. Come on, we're network admins, not mail clerks!

I'm not sure about that. The /var/log/messages file might be a better option since it contains a more comprehensive log of system activities.

The /var/log/secure file seems like the obvious choice here. It's where the system records user login and authentication events.

I think the answer is B) /var/log/secure because it contains information about user logins.
