If you have a firewall build with a Linux box, it is quite simple to install on this box: <a href=\"http:\/\/www.ilovesecure.com\/index.php\/2015\/08\/17\/monitor-traffic-with-snort-intrusion-detection\/\">how to install snort<\/a>.<br \/>\nI case you have a standard appliance (a standard firewall), you can not install any specific software, but you ca still monitor the traffic using some mirror functionality of your switch. Install Snort on a linux box using the same blog <a href=\"http:\/\/www.ilovesecure.com\/index.php\/2015\/08\/17\/monitor-traffic-with-snort-intrusion-detection\/\">how to install snort<\/a> then in the switch were your firewall is connected, mirror the traffic of the port where the firewall is connected to another port where you connect the linux box.<br \/>\nIn this way all the traffic going out through the firewall is send in the same time to the linux box where Snort is monitoring the traffic.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Antivirus are not able to detect any malware.
