Vulnerability discussion

The sysctl.conf file specifies the values for kernel parameters to be set on boot. These settings can affect the system's security.

Check content

Check /etc/sysctl.conf ownership. # ls -lL /etc/sysctl.conf If /etc/sysctl.conf is not owned by root, this is a finding.

Fix text

Use the chown command to change the owner of /etc/sysctl.conf to root: # chown root /etc/sysctl.conf

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.
