High Security Web browsing using a proxy computer.

Browsing the internet frequently results in infection with malicious code. This occurs because many web sites use active content. Displaying this active content often exposes vulnerability in the PC operating systems.

Antivirus and restriction on active content have been used to reduce the vulnerability during web browsing. However, Antivirus must keep with vulnerabilities and, even then, they cannot prevent damage from zero day exploits. Restrictions on active content reduce usability and the restrictions are often overcome by social engineering attacks.

Establish a small inexpensive server in the home network. A browser runs on this server and a remote desktop access protocol such as RDP is used by the end user on his client to run the browser. Active content runs on the browser instead of on the end user PC. A pristine environment can be established each time the browser is started or when the server is rebooted to remove any malicious code that may have temporarily infected the server. This is illustrated in the attached Figure.
