大家好,
我刚刚重装的centos7(CentOS-7.0-1406-x86_64-DVD.iso)
用yum update之后的版本是:
Linux localhost.localdomain 3.10.0-327.3.1.el7.x86_64 #1 SMP Wed Dec 9 14:09:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
在yum update过程中,SELinux有几个Alert,然后光驱就弹出了. 不知道是不是被攻击?该怎么办?谢谢
附件audit.word就是我系统的/var/log/audit/audit.log。因为论坛只允许上传特定格式的文件,所以我改了一下文件后缀
