IIS buffer overflows and firewalls

The application-control engine of Air Gap technology is designed to allow
you to generate granular rules for the application at hand, without
arbitrarily selecting a maximum length (although you can also set length
requirements). The filtering takes place behind a physical
disconnection (and secure reverse proxy).

Inspection can be based on examining the URL itself, the parameters, the
HTTP methods, etc. - both length and values can be examined, and only
acceptable URLs are allowed to pass to the server. It all happens on the
safe side of the air gap, so hackers cannot bypass the inspection.

You do not need to restrict all of the URLs with global rules -- you can
set rules per URL as well. The rules would be based upon what the back-end
applications support; in fact, you could even "record" legitimate usage of
the application and have the system generate rules for you (which you can
tweak as necessary).
