[Open Source] IisShield - Application Layer Firewall   

I'm proud to announce the release of IisShield 2.2.1 with support for
IIS 4.0, IIS 5.x and IIS 6.0.

IisShield is an ISAPI Filter for IIS that allows you to filter
incoming HTTP traffic thereby preventing known and unknown attacks by
maliciously formed requests, etc. It works in a similar way to the
Microsoft provided URLScan, however, it allows a more detailed
configuration and additional features like RFC compliance, header and
URL high bit detection, HTTP version validation, URL scheme
validation, Server header customization and more.

Some new features include the ability to define zones with specific
rules. With this feature, rules can be split into zones allowing the
filtering process to be applied in a per-zone scope versus a per-
server scope. Zones are used to specify which requests are included or
excluded from the filtering engine.

I've decided to open source IisShield.
Feel free to browse and examine the code.
