Cookie Security: Persistent Session Cookie

ABSTRACT

永久性會話 cookie 可導致危及帳戶安全。

EXPLANATION

永久性會話 cookie 在用戶關閉了瀏覽器后仍然保持有效，并通常用作“記住我的信息”功能的一部分。因此，即使在用戶關閉了瀏覽器后，永久性會話 cookie 也會使他們保持應用程序認證狀態 — 假設他們沒有明確注銷。這就意味著如果第二個用戶打開瀏覽器，他將以上個用戶的身份自動登錄。除非在受控環境中部署了應用程序，而在該環境中，不允許用戶從共享計算機登錄，否則即使用戶關閉了瀏覽器，攻擊者也可能危及用戶帳戶的安全。


例：以下配置將會話 cookie 設置為在 2 小時后過期。

session.cookie_lifetime = 7200;
