The HP FlexFabric Switch must protect against or limit the effects of denial of service (DoS) attacks by employing control plane protection.

Description
The Route Processor (RP) is critical to all network operations because it is the component used to build all forwarding paths for the data plane via control plane processes. It is also instrumental with ongoing network management functions that keep the routers and links available for providing network services. Any disruption to the Route Processor or the control and management planes can result in mission-critical network outages. A DoS attack targeting the Route Processor can result in excessive CPU and memory utilization. To maintain network stability and Route Processor security, the router must be able to handle specific control plane and management plane traffic that is destined to the Route Processor. In the past, one method of filtering was to use ingress filters on forwarding interfaces to filter both forwarding path and receiving path traffic. However, this method does not scale well as the number of interfaces grows and the size of the ingress filters grow. Control plane policing increases the security of routers and multilayer switches by protecting the Route Processor from unnecessary or malicious traffic. Filtering and rate limiting the traffic flow of control plane packets can be implemented to protect routers against reconnaissance and DoS attacks, allowing the control plane to maintain packet forwarding and protocol states despite an attack or heavy load on the router or multilayer switch.

Who does this work

12 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-80617r1_chk)

Verify that there is a control plane policy configured on the HP FlexFabric to rate limit control plane traffic using the following command: display qos policy control-plane slot 1. If the HP FlexFabric Switch is not configured to rate limit control plane traffic, this is a finding.
