InformationThe /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.
SolutionRun the following command to set permissions on /etc/group :
# chown root:root /etc/group
# chmod u-x,go-wx /etc/group
