SV-15473r2_rule Two-factor authentication must be implemented to restrict access to all network elements.

Vulnerability discussion

Without secure management implemented with authenticated access controls, strong two-factor authentication, encryption of the management session and audit logs, unauthorized users may gain access to network managed devices compromised, large parts of the network could be incapacitated with only a few commands.

Check content

Review all network element configurations to ensure that an authentication server is being used. Then verify that a two-factor authentication method has been implemented. The RADIUS or TACACS server referenced in the configurations will call a two-factor authentication server. If two-factor authentication is not being used to access all network elements, this is a finding.

Fix text

The network administrator must ensure strong two-factor authentication is being incorporated in the access scheme.

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.
