Medium Severity
<VulnDiscussion>Authenticating all devices as they connect to the network is the baseline of a good security solution. This is especially important prior to posture assessment to ensure authorized devices are online and have the proper posture prior to accessing the production network.
Device authentication is a solution enabling an organization to manage devices. It is an additional layer of authentication ensuring that only specific preauthorized devices can access the system. Authentication methods for NAC include, but are not limited to, Kerberos, MAC, or other protocols.
The IP Assignment Forescout configuration ensures any IP addresses that should be managed by the configured network will go through the policies within Forescout. Forescout policy structure is applied in a "waterfall" like way that assures all IP addresses start with the top most policy and flow down the policy tree. This policy flow ensures that all endpoints are properly identified, classified, and authenticated prior to the posture assessment.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
