5.2.6 IPS
To provide application servers in the Internet, administrator may need to open specific ports for the services.
However, there are some risks to always open service ports in the Internet. In order to avoid such attack risks,
it is important to enable IPS functions.
Intrusion Prevention System (IPS) is network security appliances that monitor network and/or system
activities for malicious activity. The main functions of IPS are to identify malicious activity, log information

intrusion activities when needed. You can also enable the log alerting so that system will record Intrusion
events when corresponding intrusions are detected.

provides TCP port 8080 for remote
administration. So, remote users or unknown
users can request those services from Internet.
With IPS enabled, the gateway can detect
incoming attack packets, including the TCP
ports (25, 80, 110, 443 and 8080) with services.
It will block the attack packets and let the
normal access to pass through the gateway
