对用户进行操作日志审计

Linux下利用日志对用户进行操作审计为了服务器的安全，以及避免日常运维中的一些误操作。

我们经常编辑/etc/profile文件，添加

HISTSIZE=1000

HISTTIMEFORMAT="%Y/%m/%d %T ";export HISTTIMEFORMAT

export HISTORY_FILE=/var/log/audit.log

export PROMPT_COMMAND='{ thisHistID=`history 1|awk "{print \\$1}"`;lastCommand=`history 1| awk "{\\$1=\"\" ;print}"`;user=`id -un`;whoStr=(`who -u am i`);realUser=${whoStr[0]};logMonth=${whoStr[2]};logDay=${whoStr[3]};logTime=${whoStr[4]};pid=${whoStr[6]};ip=${whoStr[7]};if [ ${thisHistID}x != ${lastHistID}x ];then echo -E `date "+%Y/%m/%d %H:%M:%S"` $user\($realUser\)@$ip[PID:$pid][LOGIN:$logMonth $logDay $logTime] --- $lastCommand ;lastHistID=$thisHistID;fi; } >> $HISTORY_FILE'

创建审计文件

touch /var/log/audit.log

chown nobody:nobody /var/log/audit.log

chmod 002 /var/log/audit.log

chattr +a /var/log/audit.log

source /etc/profile

你所有的操作记录就被记录下在 /var/log/audit.log

查看：

[root@liao day02]# cat /var/log/audit.log
