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.
Run the following command to determine the permissions on the /etc/group file:
/bin/ls -l /etc/group
-rw-r--r-- 1 root root <size> <date> /etc/group
Owner should be root and group should be root.
If the ownership of the /etc/group file are incorrect, run the following command to correct them:
/bin/chown root:root /etc/group
root:root
