Discussion

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

Check Content

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 Text

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