The Security Administrator is the one who will receive security alerts if the
'Security Alerts' option is set. It can be a username or an email.


The Security Level menu allows you to select one of the six preconfigured security levels
provided with msec. These levels range from poor security and ease of use, to
paranoid config, suitable for very sensitive server applications:


<span foreground=\"royalblue3\">Poor</span>: This is a totally unsafe but very
easy to use security level. It should only be used for machines not connected to
any network and that are not accessible to everybody.


<span foreground=\"royalblue3\">Standard</span>: This is the standard security
recommended for a computer that will be used to connect to the Internet as a
client.


<span foreground=\"royalblue3\">High</span>: There are already some
restrictions, and more automatic checks are run every night.


<span foreground=\"royalblue3\">Higher</span>: 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.


<span foreground=\"royalblue3\">Paranoid</span>: This is similar to the previous
level, but the system is entirely closed and security features are at their
maximum")));
