SV-39098r1_rule System files, programs, and directories must be group-owned by a system group.

Vulnerability discussion

Restricting permissions will protect the files from unauthorized modification.

Check content

Check the group ownership of system files, programs, and directories. Procedure: # ls -lLa /etc /bin /usr/bin /usr/lbin /usr/ucb /sbin /usr/sbin If any system file, program, or directory is not group-owned by a system group, this is a finding. For this check, the system-provided "ipsec" group is also acceptable.

Fix text

Change the group owner of system files to a system group. Procedure: # chgrp sys /path/to/system/file (System groups other than sys may be used.)

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
