Use Basic authentication to require that users provide a valid user name and password to access content. All major browsers support this authentication method and it works across firewalls and proxy servers. The disadvantage of Basic authentication is that it transmits passwords across the network using weak encryption. You should use Basic authentication only when you know that the connection between the client and the server is secure.
Disable Anonymous authentication if you use Basic authentication. The first request that all browsers send to a server is for anonymous access to server content. If you do not disable Anonymous authentication, users can anonymously access all the content on your server, including restricted content.
