Join Kevin Skoglund for an in-depth discussion in this video Session hijacking, part of Programming Foundations: Web Security.
Once you realize some of the problems with storing…sensitive data in cookies, like we saw in the last movie,…you may choose to store that data in a session instead.…But sessions have their own pitfalls to watch out for.…Primarily, session hijacking.…Remember, the way that sessions work…is that we store sensitive information on the web server,…and then we send the browser a cookie…with a session ID to reference that information.…The information is safer…because it's never sent to the browser.…You can't view it in the cookie, and you can't see it…while it's in transit.…
However, the session ID is sent to the browser,…and a hacker can potentially steal that session ID…the same way that they steal cookies.…Only stealing a session ID can be much more valuable,…because a session often contains…your logged in status.…This allows a user to assume your identity and be you.…Let's say, for example, that you're logged into…a site like Facebook.…If a hacker can successfully hijack your session,…then to Facebook, they look like they are you,…
