Vulnerability discussion

Proper file permissions and ownership ensures that only designated personnel in the organization can access error messages.

Check content

Check the permissions of the /var/adm/messages file: # ls -l /var/adm/messages Check the permissions of the /var/adm directory: # ls -ld /var/adm If the owner and group of /var/adm/messages is not root and the permissions are not 640, this is a finding. If the owner of /var/adm is not root, group is not sys, and the permissions are not 750, this is a finding.

Fix text

The root role is required. Change the permissions and owner on the /var/adm/messages file: # chmod 640 /var/adm/messages # chown root /var/adm/messages # chgrp root /var/adm/messages Change the permissions and owner on the /var/adm directory: # chmod 750 /var/adm # chown root /var/adm # chgrp sys /var/adm

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.
