Network Associates has announced software designed to help companies not only detect network- and system-level attacks, but also block them.

One of the products from Network Associates is a desktop version of a server-based intrusion-prevention technology that the company acquired through its $120m purchase of Entercept Security Technologies in May.

The product, called McAfee Entercept Desktop, uses a combination of virus signatures and behavioural rules to detect and block attacks at the desktop. Agent software is installed on individual desktops and is centrally managed using McAfee Entercept Management software.

Also announced was an enhanced version of McAfee IntruShield, a network intrusion-prevention product that Network Associates obtained in its $100m purchase of IntruVert earlier this year.

Last week NetScreen Technologies also announced a "deep-inspection" firewall that combines signature-, policy- and network-behaviour-based approaches to block application-level attacks. Teros also announced an enhanced version of its host-based intrusion-prevention product.

Unlike intrusion-detection products, intrusion-prevention tools automatically prevent unauthorised or malicious tasks from executing.
