Discussion

Group passwords are typically shared and should not be used. Additionally, if password hashes are readable by non-administrators, the passwords are subject to attack through lookup tables or cryptographic weaknesses in the hashes.

Check Content

Check the /etc/group file for password hashes.
# cut -d : -f 2 /etc/group | egrep -v '^(x|!)$'
If any password hashes are returned, this is a finding.

Fix Text

Edit /etc/group and change the password field to an exclamation point (!) to lock the group password.
