GIAC Certified Incident Handler (GCIH) — Question 23

What UNIX component can be used to enforce password complexity requirements?

Answer options

• A. PAM
• B. SYSKEY
• C. Shadow
• D. NTDS

Correct answer: A

Explanation

PAM, or Pluggable Authentication Modules, is the correct answer as it allows for the implementation of various authentication methods, including enforcing password complexity. SYSKEY is a Windows feature related to securing password data, while Shadow is a file that stores encrypted user passwords in UNIX but does not enforce complexity. NTDS is associated with Active Directory in Windows and is not relevant to UNIX systems.
