=for HTML =head1 NAME App::Monport - Monitor network ports for changes =head1 SYNOPSIS Run this to see available sub-commands (use -h to get help): $ monport =head1 DESCRIPTION Use this application to find out whether some new ports have been opened (or existing ones have been closed). More open ports mean bigger attack surface and consequently higher security risk. First you should run a base scan, like: $ monport base --name "test scan" localhost 192.168.1.0/24 Later on check whether some changes in ports' state took place: $ monport diff --name "test scan" 192.168.1.10 () has changes in port(s) state 3333 (dec-notes) -- not-open => open To check regularly create a cronjob like: * 21 * * 5 monport diff --name "test scan" --email jdoe@example.com =head1 INSTALLATION To install this module, run: $ cpanm App::Monport when using L. Of course you can use your favorite CPAN client or install manually by cloning the L and then running: perl Build.PL ./Build ./Build test ./Build install =head1 SOURCE REPOSITORY L =head1 AUTHOR Jozef Reisinger, Ereisinge@cpan.orgE =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2015 by Jozef Reisinger.
