SV-80543r1_rule HP FlexFabric Switch must authenticate all endpoint devices before establishing a network connection using bidirectional authentication that is cryptographically based.

Vulnerability discussion

Controlling LAN access via 802.1x authentication can assist in preventing a malicious user from connecting an unauthorized PC to a switch port to inject or receive data from the network without detection.

Check content

Verify all access switch ports connecting to LAN outlets are configured for 802.1x or MAC authentication as shown in this configuration example. 802.1x example: interface Ten-GigabitEthernet1/0/4 port link-mode bridge port access vlan 200 dot1x If all access switch ports connecting to LAN outlets are not configured for 802.1x, this is a finding.

Fix text

Configure 802.1 x authentications on all host-facing access switch ports. To authenticate those devices that do not support 802.1x, MAC Authentication Bypass must be configured.

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.
