Explanation

rkhunter (Rootkit Hunter) is a Unix/Linux security tool designed to scan systems for rootkits, backdoors, and local exploits - making B correct. It checks for suspicious file permissions, hidden files, and known rootkit signatures to alert administrators of potential compromises.

A is wrong - Log file management is handled by tools like logrotate, not rkhunter.
C is wrong - Package management belongs to tools like apt, yum, or dnf.
D is wrong - Automated host scanning is the domain of tools like Nessus or OpenVAS; rkhunter scans only the local host and is not an automated scheduler itself.

Memory tip: Break down the name - rk = rootkit, hunter = it hunts them. If you see "rootkit" in an answer choice, that's your signal.
