[ILUG-BOM] separating JS/ java code from HTML on a network ???

[Ranjeet Walunj]

Hi, How does one protect themselves from malicious Java Script or Java?? How can one do this, other than totally filtering out Java Script or Java totally, is there any other way one can protect a node in a network which is online, and behind a firewall? Firewalls are unable to do so, since JavaScript communication takes place threw port 80 or the HTTP layer. (AFAIK...not sure ..comment) So there is no way of differentiate it from normal HTML or is there? Ranjeet
