The task was to write a driver to look through the network traffic in search of HTTP connections (HTTP is detected on the content of the TCP-stream, not by port); each outgoing HTTP request is compared with the set of the configured rules and if a rule forbids a request to the resource, then, instead of server answer, the driver inserts a false answer with the page corresponding to the forbidding rule, into the TCP stream.

The task was to write a utility that allow address to a specific server under FTP protocol by creation of network disk (at that, the disk must look as usual network disk in Windows). Also it was required to supply the maximum independence of separate program components in order to replace FTP protocol, if necessary, with any other without significant expenses.

The task was to develop a driver which can allow/forbid switching-on the monitor on system events that usually result in such switching:
