CompTIA Linux+ XK0-006 (V8) Practice Question

The correct command to initialize the file properties database for rkhunter is rkhunter --propupd. This command creates a baseline by storing the current properties (hashes, permissions, etc.) of important system files in /var/lib/rkhunter/db/rkhunter.dat. Subsequent scans will compare the live system against this baseline to detect unauthorized changes. The rkhunter --update command is used to download the latest threat signature and data files, which is a different function. The rkhunter --check command initiates a scan, which would produce many false positives if a baseline has not first been established. The rkhunter --config-check command is used to validate the syntax of the configuration file, not to create a data baseline.
