The key protocol used in Enterprise mode security, RADIUS, is a centrally managed AAA protocol (Authentication, Authorisation, Accounting). This allows each user to have separate credentials. Enterprise: This mode uses a Remote Authentication Dial in User Service (RADIUS) server to handle authentication to the network.All clients use the same PSK to connect to the network. Personal: This mode uses a Pre-Shared Key (PSK), similar to a passphrase for authenticating clients to the network.The following two security modes are available when handling authentication to WPA networks:
A comparison of these protocols, along with the newer WPA3 protocol will be detailed in a later blog post. Delving into each of these protocols inner workings is beyond the scope of this blog, however, it is worth knowing that the newer WPA protocols are more secure than their predecessors.
