Ace the SISE 2025 Challenge – Master the Cisco Identity Services Engine Like a Pro!

The most suitable protocol for managing network devices securely within Cisco Identity Services Engine (ISE) is SSH (Secure Shell). SSH is a cryptographic network protocol that provides a secure channel over an unsecured network in a client-server architecture, allowing for encrypted communication between devices.

In the context of Cisco ISE, SSH is frequently employed to manage switches, routers, and other network devices securely. This is essential for the protection of administrative tasks and access, ensuring that commands sent to network devices remain confidential and are resistant to eavesdropping or man-in-the-middle attacks.

Other options may serve different purposes in networking:

- RADIUS (Remote Authentication Dial-In User Service) is primarily used for authentication, authorization, and accounting (AAA) services rather than direct management access.

- HTTPS (Hypertext Transfer Protocol Secure) is used for secure communication over a computer network, particularly for web interfaces and APIs, but it is not specifically designed for device management in the same way SSH is.

- IPSec (Internet Protocol Security) is a set of protocols used to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session. It is more associated with securing end-to-end connections rather than managing devices directly.

Therefore, SSH
