Dell OS10 Switch Layer 2 Switch Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Dell OS10 Switch must have Storm Control configured on all host-facing switch ports.
A traffic storm occurs when packets flood a LAN, creating excessive traffic and degrading network performance. Traffic storm control prevents network disruption by suppressing ingress traffic when ...Rule Low Severity -
The Dell OS10 Switch must have IGMP or MLD Snooping configured on all VLANs
IGMP and MLD snooping provides a way to constrain multicast traffic at Layer 2. By monitoring the IGMP or MLD membership reports sent by hosts within a VLAN, the snooping application can set up Lay...Rule Low Severity -
The Dell OS10 Switch must implement Rapid Spanning Tree Protocol (STP) where VLANs span multiple switches with redundant links.
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 provide high availability...Rule Medium Severity -
The Dell OS10 Switch must enable Far-End Failure Detection (FEFD) to protect against one-way connections.
In topologies where fiber-optic interconnections are used, physical misconnections can occur that allow a link to appear to be up when there is a mismatched set of transmit/receive pairs. When such...Rule Medium Severity -
The Dell OS10 Switch must have the default VLAN pruned from all trunk ports that do not require it.
The default VLAN (i.e., VLAN 1) is a special VLAN used for control plane traffic such as Spanning-Tree Protocol (STP), Dynamic Trunking Protocol (DTP), VLAN Trunking Protocol (VTP), and Port Aggreg...Rule Medium Severity
