The Basic button installs a bare bones selection of ports to monitor while still providing

sufficient coverage to detect many intruder scans. The Standard option extends this

coverage by introducing additional monitored ports for early detection of intruder scans.

The Strict button installs a comprehensive selection of ports to monitor and should be

sufficient to detect most scans.

Warning

The list of network ports can be freely edited; however, adding network ports used by

services running on the SnapGear unit (such as telnet) may compromise the security of

the device and your network. It is strongly recommended that you use the pre-defined

lists of network ports only.

Advanced Intrusion Detection and Prevention (Snort and IPS)

Advanced Intrusion Detection and Prevention is based on two variants of the tried and

tested intrusion detection and prevention system Snort v2.

Snort in IDS (Intrusion Detection System) mode resides in front of the firewall, and

detects and logs a very wide range of attacks. Snort in IPS (Intrusion Prevention

System) mode resides behind the firewall, and detects and blocks a wide range of

attacks.
