Abstract
An active filter monitors a web browser session to identify executable code transmitted in the session. The executable code may be analyzed to determine if the code is digitally signed. When the code is digitally signed by the web server or by another trusted source, the code may be executed. When the code is neither digitally signed or when the source is not trusted, the code may be rejected and not executed. The filter may be implemented as a web browser component or plugin, as well as a gateway device, proxy, or other service. The filter may also be implemented on the server side to reject incoming data that may include unauthenticated code.
