Vulnerability discussion

To centralize the management of privileged account crontabs, of the default system accounts, only root may have a crontab.

Check content

Check the cron.allow and cron.deny files for the system. # more /etc/cron.d/cron.allow # more /etc/cron.d/cron.deny If a default system account (such as bin, sys, adm, or others) is listed in the cron.allow file, or not listed in the cron.deny file if no cron.allow file exists, this is a finding.

Fix text

Remove default system accounts (such as bin, sys, adm, or others) from the cron.allow file if it exists, or add those accounts to the cron.deny file.

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.
