EAP-TLS and PEAP both provide secure authentication methods, but they differ in their requirements for client-side authentication. EAP-TLS requires both the client (supplicant) and the server to authenticate each other with certificates, thereby ensuring a very high level of security. On the other hand, PEAP requires a server-side certificate to create a secure tunnel and allows the client to authenticate using less stringent methods, such as a username and password, which are then protected by the tunnel. This makes PEAP more flexible in environments where client-side certificates are not feasible.

Protecting an Aruba Mobility Controller from unauthorized access involves several layers of security. One recommendation is to change the password recovery password, which is a special type of password used to recover access to the device in the event the admin password is lost. Changing this to something complex and unique adds an additional layer of security in the event the physical security of the device is compromised.

Devices use the Diffie-Hellman exchange to agree on a shared secret in a secure manner over an insecure network. The main purpose of this cryptographic protocol is to enable two parties to establish a shared secret over an unsecured communication channel. This shared secret can then be used to encrypt subsequent communications using a symmetric key cipher. The Diffie-Hellman exchange is particularly valuable because it allows the secure exchange of cryptographic keys over a public channel without the need for a prior shared secret. This protocol is a foundational element for many secure communications protocols, including SSL/TLS, which is used to secure connections on the internet. References to the Diffie-Hellman protocol and its uses can be found in standard cryptographic textbooks and documentation such as those from the Internet Engineering Task Force (IETF) and security protocol specifications.
