Ensure the Sudo Timeout Period Is Set to Zero

ÉlevéeNiveau 1Automatiséemacos

Description

The sudo command allows the user to run programs as the root user. Working as the root user allows the user an extremely high level of configurability within the system. This control, along with the control to use a separate timestamp for each tty, limits the window where an unauthorized user, process, or attacker could utilize legitimate credentials that are valid for longer than required. Audit: Requires a 0.0 minute sudo timestamp timeout and /etc/sudoers.d owned by root:wheel. Run as root.
