Description:
The /etc/group- file contains a backup list of all the valid groups defined in the system.
Rationale:
It is critical to ensure that the /etc/group- file is protected from unauthorized access.
Although it is protected by default, the file permissions could be changed either
inadvertently or through malicious actions.
Audit:
Run the following command and verify Uid and Gid are both 0/root and Access is 644 or
more restrictive:
# stat /etc/group- Access: (0644/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
Remediation:
Run the following command to set permissions on /etc/group- :
# chown root:root /etc/group-
# chmod u-x,go-wx /etc/group-
Parameter:
[root, root, root]
Technical Mechanism:
Run the following command to set permissions on /etc/group- :
# chown root:root /etc/group-
# chmod u-x,go-wx /etc/group-
