SV-39848r1_rule The root account must not be used for direct logins.

Vulnerability discussion

Direct login with the root account prevents individual user accountability. Acceptable non-routine uses of the root account for direct login are limited to emergency maintenance, the use of single-user mode for maintenance, and situations where individual administrator accounts are not available.

Check content

Check if the root is used for direct logins. Procedure: # last root | grep -v reboot If any direct login records for root exist, this is a finding. Verify the root user is configured as a role, rather than a normal user. Procedure: # egrep '^root:' /etc/user_attr If the returned line does not include "type=role", this is a finding.

Fix text

Convert the root user into a role. # usermod -K type=role root Add the root role to authorized users' logins. # usermod -R root

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.
