Restrict the mode of the /var/log directory

var-log-dir-mode · UBUNTU ≥ 22 · 1 impl

Description

The /var/log directory must have mode 0755 or less permissive so that unprivileged users cannot create, rename, or remove files in the system log directory.

Rationale

An overly permissive /var/log directory mode would allow unauthorized users to tamper with log files, undermining the integrity of the audit trail.
