Abstract

The expansion of web based applications has increased browser side security risks, particularly through malicious Java Script exploitation leading to data exfiltration. Conventional endpoint security mechanisms primarily emphasize network-layer monitoring, leaving client side browser activities less protected. This study proposes a browser extension-based endpoint security solution employing a rule based Java Script monitoring approach to detect spyware behavior and prevent unauthorized data transmission. Using the Research and Development (R&D) methodology, the system was designed, implemented and evaluated through controlled attack simulations. The extension monitors DOM access, local storage usage and outbound HTTP/HTTPS requests based on predefined detection rules. Experimental results across ten simulated scenarios demonstrate an 80% detection rate. The findings indicate that rule based client side monitoring offers a lightweight and practical approach to strengthening browser-level endpoint security.
