cyberstrikeus 6.1.3 Ensure permissions on /etc/group are configured (Automated)
Description
The /etc/group file contains a list of all the valid groups defined in the system. The command below allows read/write access for root and read access for everyone else.
Rationale
The /etc/group file needs to be protected from unauthorized changes by non-privileged users, but needs to be readable as this information is used with many non-privileged programs.
Audit Procedure
Run the following command and verify Uid and Gid are both 0/root and Access is 644:
# stat /etc/group
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)
Expected Result
Uid and Gid should both be 0/root and Access should be 644.
Remediation
Run the following command to set permissions on /etc/group:
# chown root:root /etc/group
# chmod 644 /etc/group
