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.
Fix:
Run the following commands to set permissions on /etc/group- # chown root:root /etc/group- # chmod u-x,go-wx /etc/group-
Parameter:
[110100100, 0, 0]
Technical Mechanism:
Run the following commands to set permissions on /etc/group- # chown root:root /etc/group- # chmod u-x,go-wx /etc/group-
