We road-test six hardware and software-based systems. Intrusion detection systems (IDS) are yet another tool offered to Security Administrators to augment their network security arsenal.

Despite a rocky beginning, intrusion detection and prevention systems are an important part of any security arsenal. We road-test six hardware and software-based systems. Intrusion detection ...

In our tests of five leading network intrusion-detection systems and the popular open source Snort, performance was spotty during baseline testing and degraded by as much as 50% on some products ...

Intrusion detection systems work in a number of ways. A network-based IDS relies on network sensors that monitor packets as they go by. Typically, a network-based IDS comprises sensors at network ...

Intrusion detection and prevention systems enable federal agencies to identify and block malicious threats.

The risk of hacking attacks and network intrusions are facts of life for everyone who ventures online. Your system's firewall and its intrusion detection system both work to protect you against ...

This is where intrusion detection systems (IDS) come in. As the name implies, an IDS monitors the network for suspicious behavior and issues alerts when such activities are discovered.

These come in two varieties. The first, network-based intrusion detection systems (NIDS), live on the network. Specifically, they watch incoming and outgoing network traffic.

Intrusion-detection systems (IDS) are quickly becoming an integral part of any organization’s network. For most companies, implementing an IDS is the next logical step after deploying a firewall ...
