Frequently Asked Questions

What is Network Level Authentication (NLA)?
Network Level Authentication (NLA) is an authentication method that can be used to enhance Remote Desktop Session Host server security by requiring that the user be authenticated to the Remote Desktop Session Host server before a session is created. Network Level Authentication completes user authentication before you establish a remote desktop connection and the logon screen appears.

What is defense-in-depth?
In information security, defense-in-depth refers to an approach in which multiple layers of defense are in place to help prevent attackers from compromising the security of a network or system.
