A zero-trust network is true to its namesake: zero trust. Zero-trust networks provide continuous authentication of users and activities on the network. This is in contrast to what traditional network authorization schemes do: authenticate users once, at the time that they initially sign onto the network.
With a zero-trust network, elements of user authentication, such as ID/password, location, workstation or device ID, etc., are all used to determine if a user should be authorized for network access. The zero-trust network performs this authorization continuously, as it re-authenticates each user for security clearance each time the user wishes to access another IT asset on the network.
