Description |
---|
Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) devices should be deployed at strategic locations within the network. At a minimum, they should be deployed within the DMZ and behind the firewall. It is important to not only monitor traffic entering the enclave but also leaving. Placing an IDS behind the firewall will provide a clear analysis of what type of traffic and potential attacks are passing through the firewall. Monitoring outbound traffic enables the network operator to detect an attack towards another network with the local enclave as the base. Enclaves are at risk and DoD data could be compromised if wireless scanning is not conducted to identify unauthorized WLAN clients and access points connected to or attempting to connect to the network. An IDS must be deployed capable of monitoring IEEE 802.11 transmissions within all DoD LAN environments and detect nearby unauthorized WLAN devices. Network monitoring is not a function of DNS. |
