7.1.3 Ensure access to /etc/group is configured

Information

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.

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.

Solution

Run the following commands to remove excess permissions, set owner, and set group on /etc/group :

# chmod u-x,go-wx /etc/group
# chown root:root /etc/group
