Vulnerability discussion

Enforcing a minimum password lifetime helps prevent repeated password changes to defeat the password reuse or history enforcement requirement.Restricting this setting limits the user's ability to change their password. Passwords need to be changed at specific policy-based intervals; however, if the network device allows the user to immediately and continually change their password, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.This control does not include root account or the account of last resort. For network devices, implementation of this requirement could cause emergency maintenance issues if applied to these local accounts. For example, after maintenance by maintenance personnel who are not normally authorized access to these passwords, the passwords will need to be changed. This is the same as the requirement to change the password when a system administrator with knowledge of the passwords for the root or account of last resort leaves the organization.

Check content

Determine if the network device enforces 24 hours as the minimum password lifetime. This requirement may be verified by demonstration or configuration review. If the network device does not enforce 24 hours as the minimum password lifetime, this is a finding.

Fix text

Configure the network device to enforce 24 hours as the minimum password lifetime.

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.
