Vulnerability discussion

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk.A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, Internet). A remote connection is any connection with a device communicating through an external network (e.g., the Internet).Because of the challenges of applying this requirement on a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability. For network device management, this has been determined to be network management device addresses, SNMP authentication, and NTP authentication.

Check content

Verify that RiOS is configured to authenticate network management endpoint devices before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based (network management portion of the requirement). Navigate to the device CLI Type: enable Type: show configuration full Verify that 'no telnet-server enable' is in the configuration Verify that 'ssh server enable' is set in the configuration Verify that 'web enable' is in the configuration Verify that 'no web http enable' is in the configuration Verify that 'web https enable' is in the configuration If any one of the above settings is missing from the configuration, this is a finding.

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.
