CakePHP Misconfiguration: Excessive Session Timeout

Abstract
如果会话超时时间过长，攻击者就会有更多时间危害用户帐户。
Explanation
会话持续时间越长，攻击者危害用户帐户的机会就越大。当会话处于活动状态时，攻击者可能会强力攻击用户的密码、破解用户的无线加密密钥或者通过打开的浏览器强占会话。如果创建大量的会话，较长的会话超时时间还会阻止系统释放内存，并最终导致 denial of service。

例 1： 以下示例显示了配置有 low 会话安全级别的 CakePHP。

    Configure::write('Security.level', 'low');
Security.level 和 Session.timeout 设置共同定义会话的有效长度。实际会话超时时间等于 Session.timeout 乘以以下倍数之一：

'high' = x 10
'medium' = x 100
'low' = x 300
