alright, with every link I send, I let the client send me a number only from his browser, not a cookie, and it's stored in the session on the server, so if you steel the session ID cookie, and try to connect through it, he has to send the same number every time, so steeling the session alone is not enough, you have to steel this number too, but this number would be sent through https, so sniffing it wouldn't give you the result.

with every click from the browser, I check for that number, if it's invalid I refuse the connection.

So if somebody steels the session cookie what difference does it make if u depend on that cookie? u added nothing but overhead to ur application, if I am not mistaken. Please be more descriptive with the solution.

Thanks

Wouldn't it be pretty useless to store this information depending on the session?

Ok if you use the values only for that session then it is useful.

 

Hence you could not provide such things like login remembrance…or am I wrong?

Subject: Re: [JoPHP] Cookies Security Threats with IE

 

Got it, a friend had solved it, with every page I would send a some secret code, generated from alot of things including a random thing, and stored in the session, so somebody steals all the cookies, he also needs to know what this code is, which is only transmitted through an https connection. I guess this would solve the thing.

The security level you seek is relevent to the importance of the data you are protecting, so if you are protecting things that are recoverable and not that much of risk you don't need to go far with protection, but if you are protecting data like credit card numbers and social security numbers you might want to ask for the username and  password before seeing this page, just like amazone; they let you shop on their site but when it comes to payement they require new login. And a good practice i saw is that if the person is idle for a certain ammount of time ( e.g not clicking or doing any action) you can terminate the session and require a new login. there are lots of things you can do but they can be expensive on the application or usibility, so you really need to know what you are protecting and how far you want to go with that.

And i agree that IP checking is not a perfferable idea, cuz some ISPs here use clustered proxies so the user would have a different IP on every new page they hit.
