Intrusion detection system
An intrusion detection system monitors network activity, looking for policy violations,
and malicious or suspicious activity. The CODA-4x8x's intrusion detection system
logs all such activity to the Security > Logs screen.
7.1.3
Device Filtering
Every networking device has a unique Media Access Control (MAC) address that
uniquely identifies it on the network. When you enable MAC address filtering on the
CODA-4x8x's firewall, you can set up a list of devices, identified by their MAC
addresses, and then specify whether you want to:
Deny the devices on the list access to the CODA-4x8x and the network (in which
case all other devices can access the network)
or
Allow the devices on the list to access the network (in which case no other
devices can access the network).
7.1.4
Port Blocking
Port blocking is a way of preventing users on the LAN from connecting with devices
on the WAN via specific services, protocols or applications. It achieves this by
permitting or denying traffic from the LAN to pass to the WAN, based on the target
port.
