Fix Recommendation

Configure the system library files to be protected from unauthorized access. Run the following command:

$ sudo find /lib /usr/lib /lib64 ! -group root -type f -exec chgrp root '{}' \;

Check Contents

Verify the system-wide library files contained in the directories "/lib", "/lib64", and "/usr/lib" are group-owned by root with the following command:

$ sudo find /lib /usr/lib /lib64 ! -group root -type f -exec stat -c "%n %G" '{}' \;

If any system-wide shared library file is returned, this is a finding.
