The HP FlexFabric Switch must provide the capability for authorized users to select a user session to capture.
Without the capability to select a user session to capture/record or view/hear, investigations into suspicious or harmful events would be hampered by the volume of information captured. The volume ...Rule Medium Severity -

The HP FlexFabric Switch must have Root Guard enabled on all ports where the root bridge should not appear.
Spanning Tree Protocol (STP) does not provide any means for the network administrator to securely enforce the topology of the switched network. Any switch can be the root bridge in a network. Howev...Rule Medium Severity -

The HP FlexFabric Switch must have BPDU Guard enabled on all user-facing access ports.
If a rogue switch is introduced into the topology and transmits a Bridge Protocol Data Unit (BPDU) with a lower bridge priority than the existing root bridge, it will become the new root bridge and...Rule Medium Severity -

The HP FlexFabric Switch must have IP Source Guard enabled on all user-facing or untrusted access switch ports.
IP Source Guard provides source IP address filtering on a Layer 2 port to prevent a malicious host from impersonating a legitimate host by assuming the legitimate host's IP address. The feature use...Rule Medium Severity -
