Vulnerability discussion

Setting the SELinux policy to "targeted" or a more specialized policy ensures the system will confine processes that are likely to be targeted for exploitation, such as network or system services.

Check content

Check the file "/etc/selinux/config" and ensure the following line appears: SELINUXTYPE=targeted If it does not, this is a finding.

Fix text

The SELinux "targeted" policy is appropriate for general-purpose desktops and servers, as well as systems in many other roles. To configure the system to use this policy, add or correct the following line in "/etc/selinux/config": SELINUXTYPE=targeted Other policies, such as "mls", provide additional security labeling and greater confinement but are not compatible with many general-purpose use cases.

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.
