As part of a serious and involved computer security plan, network intrusion detection (IDS) software provides additional protection compared to antivirus and firewall programs. Software IDS capabilities are so involved that they can actually detect whether or not a business’ traffic is a request from the Internet or a file transfer over an instant messaging program.

Network Intrusion Detection (IDS) Software Key Terms


Using network-intrusion detection software is one of the best ways to protect a computer network. While corporations use this software to identify malware and viruses, they rely on it more to detect more complicated attacks, such as data- driven attacks on applications and unauthorized logins. Network-intrusion detection software can be proactive or passive. If it’s proactive, it can reboot a server or change the device’s configurations so as to prevent an intruder from invading the network.

Network-intrusion detection software

Network-intrusion detection software closely tracks and investigates traffic on a network. It monitors for malicious activity, such as malicious SQL (structured query language) injections or DoS (denial of service) attacks.

Passive-response system

Network-intrusion detection software can be considered a passive response. A passive response system identifies the suspicious activity, logs the data and notifies the system administrator. It is then up to the administrator to take the next step to stop the attacks from occurring.

Active-response system

Network intrusion-detection software can also be proactive. This is known as action response, or reactive. An active-response system takes action against suspicious activity. After it detects an attack, an active-response system can change the network device's settings, such as firewalls or routers, reboot the server or close ports and connections.

Network based

Network-based, intrusion-detection software examines all network traffic. It also keeps track of multiple hosts. Network-based, intrusion-detection software is attached to a network device, such as a network switch or hub. This is how it can access and monitor network traffic.

Host based

Host-based, network-intrusion detection software monitors suspicious activity on a host, which is a local system. The host-based, intrusion-detection software identifies intrusions by analyzing application logs or system log files.

Firewalls

Firewalls block intruders from accessing the network. They work closely with routers, analyzing network packets and deciding if they should forward the data to the destination. Firewalls can be either software or hardware. Firewalls are not known for being as proactive as network-intrusion detection software.
