    I am not quite sure if I know what you mean, but cookies can only be accessed by the domain which set them. Other websites can't access the cookies of your website and your website can't access cookies of other websites.

    So if you're afraid that a cracker who has another website could manipulate your cookies, he can't do that, because the browser doesn't send him your cookies.
