How can remediation be configured for non-compliant devices in Cisco ISE?

For non-compliant devices in Cisco Identity Services Engine (ISE), remediation can be effectively configured by utilizing posture assessment policies that direct these devices to a quarantine VLAN. This approach allows the organization to enforce security policies by isolating non-compliant devices from the rest of the network until they meet the necessary compliance requirements.

A quarantine VLAN serves as a controlled environment where non-compliant devices can access only specific resources, such as remediation servers or secure updates. This ensures that the compromised devices do not pose a threat to the overall network security while giving users the chance to rectify compliance issues. By implementing posture assessment policies in conjunction with a quarantine VLAN, organizations can streamline their security measures and effectively manage devices that fail to meet compliance standards.

The other options, while relevant in certain contexts, do not provide the same level of effective remediation that a quarantine VLAN accomplishes. Redirecting users to an external website might not address the compliance issue directly, and notifying IT personnel manually lacks the automation and immediate corrective interventions provided by Cisco ISE. Disabling the device immediately could lead to connectivity issues without a method for the user to address the underlying compliance problems.
