Hi All,
Sorry if this is common knowledge or regularly discussed; I'm fairly new to the list. I see quite a few messages on this and other security lists about session hijacking in Web applications. Isn't it good defense for a programmer to store the IP address of the client when the session is initiated, and then compare that address against the client for each subsequent request, destroying the session if the address changes? Do many programmers really overlook this simple method to protect against such an attack? It's not perfect but should significantly increase the difficulty of such an attack with little or no annoying side effects for the legitimate user. Would it be useful to extend the session modules of the common Web scripting languages (e.g. PHP) to enable an IP address check by default?
Best Regards,
