               to the Internet as a client.

High:       There are already some restrictions, and more automatic checks are run every night.

Higher:    The security is now high enough to use the system as a server which can accept
              connections from many clients. If your machine is only a client on the Internet, you
	      should choose a lower level.

Paranoid:  This is similar to the previous level, but the system is entirely closed and security
                features are at their maximum

Security Administrator:
               If the 'Security Alerts' option is set, security alerts will be sent to this user (username or
