The Cisco ISE must be configured to dynamically apply restricted access of endpoints that are granted access using MAC Authentication Bypass (MAB). This is required for compliance with C2C Step 4.
Medium Severity
<VulnDiscussion>MAB can be defeated by spoofing the MAC address of a valid device. MAB enables port-based access control using the MAC address of the endpoint. A MAB-enabled port can be dynamically enabled or disabled based on the MAC address of the device that connects to it.
NPE devices that can support PKI or an allowed authentication type must use PKI. MAB may be used for NPE that cannot support an approved device authentication. Non-entity endpoints include IoT devices, VOIP phone, and printer.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
