Which of the following encrypts all traffic between the client agent and the Cisco ISE server for posture assessment and remediation of clients?

The correct answer highlights the role of Posture Run-Time Services in providing encryption for traffic between the client agent and the Cisco Identity Services Engine (ISE) server. This component is specifically designed to support posture assessment and remediation, ensuring that any data exchanged during these processes remains confidential and secure.

Posture Run-Time Services establish secure communication channels necessary for transmitting sensitive information related to the client's compliance status and any remediation actions that may be required. By encrypting this traffic, these services protect against eavesdropping and tampering, enhancing the overall security posture of the network.

Understanding this mechanism is crucial for ensuring that the security measures in place during client assessments are robust, facilitating a safer environment where vulnerabilities can be addressed without exposing the organization to risks associated with data interception.
