Cisco IOS Switch L2S Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Cisco switch must enable Unidirectional Link Detection (UDLD) 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 -

Group -
The Cisco 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...Rule Medium Severity -

Group -
The Cisco switch must have all disabled switch ports assigned to an unused VLAN.
A disabled port that is assigned to a user or management VLAN may become enabled by accident or by an attacker and as a result may gain access to that VLAN as a member.Rule Medium Severity -
SRG-NET-000512-L2S-000008
Group -
The Cisco 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...Rule Medium Severity -

The Cisco switch must not use the default VLAN for management traffic.
Switches use the default VLAN (i.e., VLAN 1) for in-band management and to communicate with directly connected switches using Spanning-Tree Protocol (STP), Dynamic Trunking Protocol (DTP), VLAN Tru...Rule Medium Severity
