Network Intrusion

What is network intrusion?

A network intrusion occurs when a hacker looks for security holes in a network and attempts to break in. Network intrusions affect three critical aspects of network functioning: confidentiality, integrity, and availability. The confidentiality of information stored in electronic format on computer systems connected to a network is threatened by back-door programs and keyloggers, which allow access to information to unauthorized personnel. The integrity of information stored in electronic format systems is threatened by backdoor programs and network worms, which can alter or erase information. And, finally, the availability of a network or system resource system and the availability of information stored on these systems are at also risk.

What is network intrusion prevention?

Network Intrusion Prevention Systems (also known as network IPS or simply IPS) are designed to protect large enterprise networks and information systems from unauthorized access, damage, or disruption. They monitor data packets on the network wire to determine if a hacker is attempting to break into a system or cause a denial of service attack. Network intrusion prevention systems take immediate action to stop intrusions, based on a set of rules determined by the network administrator. There is usually no disruption or delay in network service.

Network intrusion prevention systems are available as software or as dedicated hardware appliances that connect directly to a network segment and protect all of the systems and segments of the network attached to the IPS. Network IPS counteracts the rapidly evolving threats presented by the latest generation of worms, malware, and other exploits.

Why does my organization need network intrusion prevention?

Network intrusion prevention is a proactive approach to network security that identifies and responds to potential threats quickly. Network intrusion prevention systems minimize downtime caused by exploits, halt attacks before they reach computer systems, protect confidential data, make applications more secure, and help enterprises stay compliant. Without network intrusion prevention, enterprises could suffer revenue losses due to disrupted operations and damage to their brand and reputation resulting from data breaches.

How does network intrusion prevention work?

Network intrusion prevention appliances are hardware devices that proactively block attacks and protect all devices on mission-critical, enterprise-class networks. The appliances provide real-time visibility to system host details and the most critical host intrusions, including viruses and spyware. IT administrators manage, configure, and monitor all appliances across widely distributed deployments with a manager appliance.

Network intrusion prevention is a wise investment for global enterprises.
