Filter for suspicious network activity attempting to mimic a web browser

A method of detecting impersonated network traffic by a network protection system that provides protection to a protected network, the method comprising:

• enabling synchronization with generation of short-lived passwords by the respective computing devices of the protected network;
• receiving a request for communicating with at least one other computer via the World Wide Web;
• verifying, upon receiving the request, whether a short-lived password is included with the request;
• upon verification that the short-lived password is included with the request, verifying synchronization of the short-lived password with an expected value;
• upon verification of synchronization of the short-lived password, treating the request as legitimate network traffic;
• and
• otherwise, upon a lack of verification that the short-lived password is included with the request or a lack of verification of synchronization of the short-lived password, treating the request as illegitimate network traffic.

A computer system for detecting impersonated network traffic by a computing device of a protected network protected by a network protection system, the computer system comprising:

• a memory configured to store instructions;
• processor disposed in communication with said memory, wherein said processor upon execution of the instructions is configured to:
• receive installation of a browser application, the browser application configured to generate requests to communicate with other computers via the World Wide Web;
• and
• receive a configuration for the browser application to:
• obtain a short-lived password in coordination with generating a request, wherein the short-lived password is synchronized with an expected value generated by the network protection system;
• and
• insert the short-lived password into the generated request before transmitting the request,
• wherein the transmitted request is passed to the network protection system and treated as legitimate network traffic by the network protection system only if the short-lived password is verified by the network protection system.
