How do Aruba access points authenticate users to the network?

Aruba access points primarily authenticate users to the network using 802.1X authentication or pre-shared keys (PSK). 802.1X is part of the IEEE 802.1 standards for network access control, which provides an authentication mechanism to devices wishing to connect to a LAN or WLAN. It allows for a robust method of data security by enabling dynamic and individualized authentication.

In environments that employ 802.1X, users are required to provide credentials, which are then validated against a central authentication server, typically a RADIUS server. This method supports a range of authentication types, including usernames and passwords, smart cards, and certificates, making it highly scalable and secure for corporate networks.

On the other hand, pre-shared keys serve as a simpler form of authentication used mostly in smaller or less security-sensitive environments. With PSK, all users connect to the network using a shared password, which simplifies the configuration but can lead to security risks if the key is exposed.

Both native authentication mechanisms provided by Aruba access points enable secure user access, ensuring that only authenticated clients can connect to the network, effectively managing access and reducing vulnerabilities associated with unauthorized users.
