Before establishing a local, remote, and/or network connection with any endpoint device, the Cisco ISE must use a bidirectional authentication mechanism configured with a FIPS-validated Advanced Encryption Standard (AES) cipher block algorithm to authenticate with the endpoint device. This is required for compliance with C2C Step 1.
Medium Severity
<VulnDiscussion>Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. Currently, DoD requires the use of AES for bidirectional authentication since it is the only FIPS-validated AES cipher block algorithm. Because of the challenges of applying this requirement on a large scale, organizations are encouraged to apply the requirement only to those limited number (and type) of devices that truly need to support this capability.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
