<p style="font-family: Arial, sans-serif;">“猜测”是最简单的黑客攻击方式。为此，ADSelfService 
Plus提供以下功能来防范此种攻击：</p>

<p style="font-family: Arial, sans-serif;">&nbsp;</p>

<p style="font-family: Arial, sans-serif;">
作为防止攻击的主动性手段，当用户在有限时间内答错问题次数超过指定次数时，系统会阻止用户登录。<a href="../../Self-Service/Advanced/Block-User.html">点击此处</a>，了解设置阻止用户的详细步骤：</p>

<p style="font-family: Arial, sans-serif;">&nbsp; </p>

<a name=Timeout></a>会话超时 :</strong></p>

<p style="font-family: Arial, sans-serif;">&nbsp;</p>

<p style="font-family: Arial, sans-serif;">重置密码和解锁帐户是非常重要的操作，需要谨慎处理。为此，在ADSelfService 
Plus中可限制重置密码和解锁帐户的操作时间。当会话超时后，系统会锁定整个操作过程，用户需要重新开始。</p>
