The VPN Gateway must configure OCSP to ensure revoked user certificates are prohibited from establishing an allowed session.
Medium Severity
<VulnDiscussion>Situations may arise in which the certificate issued by a Certificate Authority (CA) may need to be revoked before the lifetime of the certificate expires. One example is if the certificate is known to have been compromised. When an incoming Internet Key Exchange (IKE) session is initiated for a remote client or peer whose certificate is revoked, the revocation list configured for use by the VPN server is checked to see if the certificate is valid. If the certificate is revoked, IKE will fail and an IPsec security association will not be established for the remote endpoint.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
