The SDN controller must be configured to protect against or limit the effects of denial-of-service (DoS) attacks by rate-limiting control-plane communications.
The SDN controller must be configured to protect against or limit the effects of denial-of-service (DoS) attacks by rate-limiting control-plane communications. An XCCDF Rule
The SDN controller must be configured to protect against or limit the effects of denial-of-service (DoS) attacks by rate-limiting control-plane communications.
Medium Severity
<VulnDiscussion>The SDN Controller 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 network management and provisioning functions that keep the SDN-enabled network elements and links available for providing network services. Any disruption to the SDN Controller can result in mission-critical network outages. A DoS attack targeting the SDN Controller can result in excessive CPU and memory utilization. The SDN Controller must be configured to rate-limit control-plane traffic destined to itself to mitigate the risk of a DoS attack and ensure network stability.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
