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. Groups in Linux are defined by GIDs (group IDs). Just like with UIDs, the first 100 GIDs are usually reserved for system use. The GID of 0 corresponds to the root group and the GID of 100 usually represents the users group. GIDs are stored in the /etc/groups file Rationale: The /etc/group file needs to be protected from unauthorized changes by non-priliveged users, but needs to be readable as this information is used with many non-privileged programs. Fix: If the ownership of the /etc/group file are incorrect, run the following command to correct them: # /bin/chown root:root /etc/group

[GID of ROOT, UID of ROOT]

If the ownership of the /etc/group file are incorrect, run the following command to correct them: # /bin/chown root:root /etc/group
