HP FlexFabric Switch L2S Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The HP FlexFabric Switch must have Dynamic ARP Inspection (DAI) enabled on all user VLANs.

    DAI intercepts Address Resolution Protocol (ARP) requests and verifies that each of these packets has a valid IP-to-MAC address binding before updating the local ARP cache and before forwarding the...

  • The HP FlexFabric Switch must implement Rapid STP where VLANs span multiple switches with redundant links.

    Spanning Tree Protocol (STP) is implemented on bridges and switches to prevent layer 2 loops when a broadcast domain spans multiple bridges and switches and when redundant links are provisioned to ...

  • The HP FlexFabric Switch must have all trunk links enabled statically.

    When trunk negotiation is enabled via Dynamic Trunk Protocol (DTP), considerable time can be spent negotiating trunk settings (802.1q or ISL) when a node or interface is restored. While this negoti...

  • The HP FlexFabric Switch must not have the default VLAN assigned to any host-facing switch ports.

    In a VLAN-based network, switches use the default VLAN (i.e., VLAN 1) for in-band management and to communicate with other networking devices using Spanning-Tree Protocol (STP), Dynamic Trunking Pr...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
