| V-269954 | | The Dell OS10 Switch must manage excess bandwidth to limit the effects of packet flooding types of denial-of-service (DoS) attacks. | DoS is a condition when a resource is not available for legitimate users. Packet flooding distributed denial-of-service (DDoS) attacks are referred to... |
| V-269956 | | The Dell OS10 Switch must have BPDU Guard enabled on all user-facing or untrusted access switch 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... |
| V-269957 | | The Dell OS10 Switch must have STP Loop Guard enabled on all nondesignated STP switch ports. | The Spanning Tree Protocol (STP) loop guard feature provides additional protection against STP loops. An STP loop is created when an STP blocking port... |
| V-269958 | | The Dell OS10 Switch must have Unknown Unicast Flood Blocking (UUFB) enabled. | Access layer switches use the Content Addressable Memory (CAM) table to direct traffic to specific ports based on the VLAN number and the destination ... |
| V-269959 | | The Dell OS10 Switch must have DHCP snooping for all user VLANs to validate DHCP messages from untrusted sources. | In an enterprise network, devices under administrative control are trusted sources. These devices include the switches, routers, and servers in the ne... |
| V-269960 | | The Dell OS10 Switch must have Source Address Validation (SAV) 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 th... |
| V-269961 | | The Dell OS10 Switch must have Dynamic Address Resolution Protocol (ARP) Inspection (DAI) enabled on all user VLANs. | DAI intercepts ARP requests and verifies that each of these packets has a valid IP-to-MAC address binding before updating the local ARP cache and befo... |
| V-269964 | | 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 lin... |
| V-269965 | | 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 mism... |
| V-269966 | | The Dell OS10 Switch must have all disabled switch ports assigned to an unused VLAN. | It is possible that a disabled port that is assigned to a user or management VLAN becomes enabled by accident or by an attacker and as a result gains ... |
| V-269967 | | The Dell OS10 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 Sp... |
| V-269968 | | 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)... |
| V-269969 | | The Dell OS10 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 (... |
| V-269970 | | The Dell OS10 Switch must have all user-facing or untrusted ports configured as access switch ports. | Double encapsulation can be initiated by an attacker who has access to a switch port belonging to the native VLAN of the trunk port. Knowing the victi... |
| V-269972 | | The Dell OS10 Switch must implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. | Separating critical system components and functions from other noncritical system components and functions through separate subnetworks may be necessa... |
| V-269955 | | The Dell OS10 Switch must have Root Guard enabled on all switch ports connecting to access layer switches and hosts. | Spanning Tree Protocol (STP) does not provide any means for the network administrator to securely enforce the topology of the switched network. Any sw... |
| V-269962 | | 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 ... |
| V-269963 | | 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 ... |
| V-269971 | | The Dell OS10 Switch must not have any switch ports assigned to the native VLAN. | Double encapsulation can be initiated by an attacker who has access to a switch port belonging to the native VLAN of the trunk port. Knowing the victi... |
| V-269953 | | The Dell OS10 Switch must uniquely identify all network-connected endpoint devices before establishing any connection. | Controlling LAN access via 802.1x authentication can assist in preventing a malicious user from connecting an unauthorized PC to a switch port to inje... |
