<p><span style="font-family: 'Microsoft YaHei';"> 工作中我们常常遇到，有的员工不安于被分配的权限，老是想sudo echo "ziji" /usr/bin/visudo NOPASSWD:ALL来进行提权，造成误删了数据库某条重要的数据，或者执行了一条命令对线上生产造成了严重的影响，部门老大又苦于找不到造成这种现象的操作者，CTO对你们部门直接扣除绩效，这样你们集体成了背锅侠。。。为了记录员工做的违规操作行为，所以就有了以下的方案。</span><br /><span style="font-family: 'Microsoft YaHei';"> 我们今天要学习的是：sudo日志审计，专门对使用sudo命令的系统用户记录其执行的命令相关信息，所谓日志审计，就是记录所有系统及相关用户行为的信息，并且可以自动分析，处理，展示（包括文本或着录像）</span></p>

<h2><span style="font-family: 'Microsoft YaHei';"><span style="font-size: 14px;">一）生产环境日志审计解决方案： </span> </span></h2>
<blockquote>
<p><span style="font-family: 'Microsoft YaHei';">通过环境变量命令及syslog服务进行全部日志审计（信息太大，不推荐）</span></p>
<p><span style="font-family: 'Microsoft YaHei';">sudo配合syslog服务，进行日志审计（信息较少，效果不错）</span></p>
<p><span style="font-family: 'Microsoft YaHei';">在bash解释器程序里嵌入一个监视器，让所有被审计的系统用户使用修改过的增加了监视器的特殊bash程序作为解释程序。</span></p>

<h2><span style="font-family: 'Microsoft YaHei'; font-size: 14px;">二）配置sudo日志审计</span></h2>
<p><span style="font-family: 'Microsoft YaHei';">说明：所谓sudo命令日志审计，并不记录普通用户的普通操作，而是记录，那些执行sudo命令的用户的操作。</span></p>
<h3><span style="font-family: 'Microsoft YaHei'; font-size: 13px;">１、安装sudo命令，rsyslog服务</span></h3>
<div class="cnblogs_code">

<h3><span style="font-family: 'Microsoft YaHei'; font-size: 13px;">２、配置服务</span></h3>
<p><span style="font-family: 'Microsoft YaHei'; font-size: 13px;">2.1配置系统日志/etc/rsyslog.conf，增加配置local.debug到/etc/rsyslog.conf中</span></p>
<div class="cnblogs_code">

<p>2.2配置/etc/sudoers，<span style="font-family: 'Microsoft YaHei';">增加配置 “Defaults logfile=/var/log/sudo.log” 到/etc/sudoers中，注意：不包含引号。</span></p>
<div class="cnblogs_code">
