provided with msec. These levels range from '<span weight=\"bold\">poor</span>' security and ease of use, to
'<span weight=\"bold\">paranoid</span>' 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")), \%common_opts));
