Microsoft has launched its first security software product in the form of a firewall and web caching tool. ISA Server uses packet, circuit-level and application filtering techniques to protect multiple network layers. It also supports virtual private networks and predefines about 100 application protocols.
Administrators can also add further protocols based on their type and transmission control.
The server, which includes a high-speed web cache, also provides network firewall protection, defends against external attacks and notifies network administrators of suspicious activities. Rob Enderle, an analyst at researcher Giga Information Group, said it was necessary for Microsoft to add a security element to .Net servers. The product, which will be available in standard and enterprise editions, was tested by independent facility ICSA Labs in December and awarded certification on 29 January.
