Vulnerability discussion

Disabling accounts after a limited number of unsuccessful login attempts improves protection against password guessing attacks.

Check content

Verify RETRIES is set in the login file. # grep RETRIES /etc/default/login If RETRIES is not set or is more than 3, this is a finding. Verify the account locks after invalid login attempts. # grep LOCK_AFTER_RETRIES /etc/security/policy.conf If LOCK_AFTER_RETRIES is not set to YES, this is a finding.

Fix text

Set RETRIES to 3 in the /etc/default/login file. #vi /etc/default/login Set LOCK_AFTER_RETRIES to YES in the /etc/security/policy.conf file. #vi /etc/security/policy.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.
