GIAC Penetration Tester (GPEN) — Question 55

Which of the following is a method of gathering user names from a Linux system?

Answer options

• A. Displaying the owner information of system-specific binaries
• B. Reviewing the contents of the system log files
• C. Gathering listening services from the xinetd configuration files
• D. Extracting text strings from the system password file

Correct answer: C

Explanation

The correct answer is C, as xinetd configuration files can provide information on services that may include user-related data. Option A is incorrect because displaying owner information does not directly list user names. Option B is also wrong since log files typically do not contain user names directly. Option D, while related to user information, is not the correct method specified in the question.
