Findings (MAC I - Mission Critical Classified)

Finding ID Severity Title
V-220623 High The Cisco switch must uniquely identify and authenticate all network-connected endpoint devices before establishing any connection.
V-220625 Medium The Cisco switch must manage excess bandwidth to limit the effects of packet-flooding types of denial-of-service (DoS) attacks.
V-220624 Medium The Cisco switch must authenticate all VLAN Trunk Protocol (VTP) messages with a hash function using the most secured cryptographic algorithm available.
V-220638 Medium The Cisco switch must implement Rapid Spanning Tree Protocol (STP) where VLANs span multiple switches with redundant links.
V-220639 Medium The Cisco switch must enable Unidirectional Link Detection (UDLD) to protect against one-way connections.
V-220630 Medium The Cisco switch must have Bridge Protocol Data Unit (BPDU) Guard enabled on all user-facing or untrusted access switch ports.
V-220631 Medium The Cisco switch must have Spanning Tree Protocol (STP) Loop Guard enabled.
V-220632 Medium The Cisco switch must have Unknown Unicast Flood Blocking (UUFB) enabled.
V-220633 Medium The Cisco switch must have DHCP snooping for all user VLANs to validate DHCP messages from untrusted sources.
V-220634 Medium The Cisco switch must have IP Source Guard enabled on all user-facing or untrusted access switch ports.
V-220635 Medium The Cisco switch must have Dynamic Address Resolution Protocol (ARP) Inspection (DAI) enabled on all user VLANs.
V-220645 Medium The Cisco switch must have all user-facing or untrusted ports configured as access switch ports.
V-220644 Medium The Cisco switch must not use the default VLAN for management traffic.
V-220646 Medium The Cisco switch must have the native VLAN assigned to an ID other than the default VLAN for all 802.1q trunk links.
V-220641 Medium The Cisco switch must have all disabled switch ports assigned to an unused VLAN.
V-220640 Medium The Cisco switch must have all trunk links enabled statically.
V-220643 Medium The Cisco switch must have the default VLAN pruned from all trunk ports that do not require it.
V-220642 Medium The Cisco switch must not have the default VLAN assigned to any host-facing switch ports.
V-220629 Low The Cisco switch must have Root Guard enabled on all switch ports connecting to access layer switches.
V-220636 Low The Cisco switch must have Storm Control configured on all host-facing switchports.
V-220637 Low The Cisco switch must have IGMP or MLD Snooping configured on all VLANs.
V-220647 Low The Cisco switch must not have any switchports assigned to the native VLAN.
