Which protocol is primarily used for secure management of network devices in the Aruba ecosystem?

The primary protocol used for secure management of network devices within the Aruba ecosystem is SSH (Secure Shell). SSH is designed to provide a secure channel over an unsecured network and encrypts the data being transmitted, thus protecting against eavesdropping and man-in-the-middle attacks.

In the context of managing Aruba devices, SSH allows administrators to securely access the command-line interface (CLI) of network devices, perform configurations, and execute commands without exposing sensitive information, such as usernames and passwords, in plaintext. This is particularly important in a network environment where security is a top priority due to the sensitivity of data being handled.

Additionally, SSH supports strong authentication methods and provides a secure way to manage devices remotely, making it essential for maintaining network integrity and preventing unauthorized access. This contrasts with other protocols mentioned, which do not inherently provide the same level of security for managing network devices.
