Policy states that each Windows laptop must have an approved antimalware product installed with recently updated definitions. In Cisco ISE posture, how are these checks expressed so that the agent can evaluate them?

Cisco ISE posture is built in layers. Conditions describe individual checks, and ISE provides condition types for common security software, including anti-malware conditions that verify that a supported product is installed and that its definitions are current. Requirements group one or more conditions and associate a remediation action and a message for the user. Posture policy then maps requirements to endpoints by operating system, identity group or other attributes. The posture agent downloads the applicable requirements, evaluates the conditions on the laptop and reports compliant or noncompliant to ISE, which then drives authorization. Authorization profiles define the access result, such as a VLAN or downloadable ACL; they are returned by ISE, not evaluated by the switch as checks of endpoint software. Profiling classifies a device from network attributes such as DHCP options or MAC vendor; it can identify a Windows laptop but cannot see installed applications or definition dates. TACACS+ command sets control which commands administrators may run on network devices and have nothing to do with endpoint posture. Exam caveat: the agent's compliance module must recognize the antimalware product, so keep the posture update feed current. Operational check: stop definition updates on a test laptop, confirm that it reports noncompliant for the anti-malware requirement, then update definitions and confirm compliance.
