About Authentication

Users can be “filtered” on an appliance, which means you can allow web access only for those who are able to authenticate.

Authentication is not implemented by default, but there are preconfigured authentication rule sets, which you can use.

The types of authentication that you can implement include:

• Standard authentication — You can configure authentication for users who send requests for web access under a standard protocol, such as HTTP, HTTPS, or FTP. When the authentication rule set of the default rule set system is enabled, user information is by default retrieved from an internal user database. You can change this setting and configure a different method, such as NTLM, LDAP, Kerberos, and others.
• Instant messaging authentication — You can configure authentication for users who send requests for web access under XMPP, which is the protocol used for several instant messaging services such as Jabber, Google Talk, Facebook Chat, and others.

You can also control administrator access to an appliance by setting up and maintaining administrator accounts
and roles.
