Description

To ensure accountability and prevent unauthenticated access, groups must be identified uniquely to prevent potential misuse and compromise of the system.

ℹ️ Check

Verify TOSS 5 contains no duplicate GIDs for interactive users using the following command: $ cut -d : -f 3 /etc/group | uniq -d If the system has duplicate GIDs, this is a finding.

✔️ Fix

Edit the file "/etc/group" and provide each group that has a duplicate GID with a unique GID.
