Options
- AInstall the latest OS patches.
- BSet up a personal firewall.
- CDisable the HIDS.
- DEnable WOL.
Explanation
The first and most critical step to harden a Linux server after OS installation is to install the latest OS patches to address known security vulnerabilities.
Common mistakes.
- B. Setting up a personal firewall is an important hardening step but should typically follow the application of OS patches to ensure the underlying system itself is protected against known exploits first.
- C. Disabling a Host Intrusion Detection System (HIDS) would weaken the server's security posture, as HIDS are designed to monitor for malicious activities.
- D. Enabling Wake-on-LAN (WOL) is a power management feature and is not directly related to server hardening; in some cases, if not properly secured, it could even introduce security risks.
