What effect does dynamic adjustment of access permissions have in Cisco ISE?

Dynamic adjustment of access permissions in Cisco Identity Services Engine (ISE) plays a crucial role in maintaining compliance with security policies. This functionality allows ISE to evaluate and modify the access rights of users and devices based on their current security posture, role, or context.

For example, if a user's device is found to be non-compliant with the organization’s security policies—such as having outdated antivirus software or missing security patches—the ISE can dynamically adjust the access control permissions for that device. This might mean limiting the device’s access to certain resources or placing it in a remediation VLAN until it meets the required compliance standards.

By ensuring that only compliant devices and users can access specific network resources, ISE helps organizations uphold their security policies and mitigate risks. This feature also supports adaptive security models that evolve with the changing threat landscape, promoting a more robust approach to network security management.
