Why Your Sudoers File Needs Hardening Now

Episode 24 of Linux Server Admin with Fexingo digs into a critical but often overlooked security gap: the sudoers file. Lucas and Luna walk through a real-world misconfiguration that gave an attacker passwordless root access on a monitoring server, and explain how to lock down sudo with defaults, timed credentials, command aliases, and the sudo_logsrvd audit daemon. They cover the new sudo 1.9.14 timeout policy, the difference between NOPASSWD and timed permissions, and why logging every sudo invocation matters for incident response. If you maintain Linux servers in production, this episode gives you one concrete change to make today.
