The Cisco ISE must verify host-based firewall software is running on posture required clients defined in the NAC System Security Plan (SSP) prior to granting trusted network access. This is required for compliance with C2C Step 4.

An XCCDF Rule

Description

<VulnDiscussion>Automated policy assessments must reflect the organization's current security policy so entry control decisions will happen only where remote endpoints meet the organization's security requirements. If the remote endpoints are allowed to connect to the organization's network without passing minimum-security controls, they become a threat to the entire network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
