NAME
App::Monport - Monitor network ports for changes
SYNOPSIS
Run this to see available commands:
$ monport
DESCRIPTION
Use this application to find out whether some new ports have been opened or existing ones have been closed. New open ports mean bigger attack surface and consequently higher security risk. If a port gets closed it might indicate a problem with a network service.
The application works by comparing the actual state of ports (open or closed) with the baseline scan. Any found differences are reported (via command line interface, email, twitter). Nmap
is used for doing the port scanning so you need to have it installed.
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:
PERL5LIB=/home/jdoe/perl5/lib/perl5
* 21 * * 5 /home/jdoe/perl5/bin/monport diff --name "test scan" --email jdoe@example.com
To list the executed base scans:
$ monport list
noname
test scan
To see the results of the base scan:
$ monport list -p -n 'test scan'
Base scan done: Fri Feb 12 08:41:06 2016
127.0.0.1 (localhost)
22 (ssh)
