Security "Novell NetWare "

Security
NetWare is arguably the most secure NOS. It uses public key encryption during the login process (passwords are never sent in cleartext between client and server). Plus, you cannot get
access to the local files unless you are logged in with a proper client. NetWare is the only NOS that has been certified by the National Security Agency (NSA) as C2 Red Book secure, which
means that it is secure enough for U.S. government use.

     In addition, NetWare uses NDS for the back-end authentication. Clients will send authentication requests to NDS and NDS will look up the user in the Directory and verify that the attempted login is an appropriate request and that the user information is valid.
