游戏服务器被攻击怎么解决?游戏行业由于其特殊性,很容易受到来自同行或者网络黑客的恶意攻击,而服务器遭受攻击后,若不及时解决,会对游戏用户体验造成很大的影响,进而导致用户流失,公司业务严重受损
查找攻击源
可以通过分析系统日志或登录日志文件,查看可疑信息,同时也要查看系统都打开了哪些端口,运行哪些进程,并通过这些进程分析哪些是可疑的程序
这个过程要专业技术人员根据经验和综合判断能力进行追查和分析,在发现服务器安全系统漏洞后,修复漏洞或者更改程序bug,只有将程序的漏洞修复完毕才能正式在服务器上运行
锁定可疑用户
一旦发现可疑用户,就要马上将其锁定,例如执行“w”命令后发现nobody用户应该是个可疑用户(因为nobody默认情况下是没有登录权限的),于是首先锁定此用户,执行如下操作:
[root@server ~]# passwd -l nobody
锁定之后,有可能此用户还处于登录状态,于是还要将此用户踢下线
检查关闭可疑进程
检查可疑进程的命令很多,例如ps、top等,但是有时候只知道进程的名称无法得知路径,首先通过pidof命令可以查找正在运行的进程PID,然后进入内存目录,查看对应PID目录下exe文件的信息,这样就找到了进程对应的完整执行路径
分析入侵原因和途径
既然系统遭到入侵,那么原因是多方面的,可能是系统漏洞,也可能是程序漏洞,一定要查清楚是哪个原因导致的,并且还要查清楚遭到攻击的途径,找到攻击源,因为只有知道了遭受攻击的原因和途径,才能删除攻击源同时进行漏洞的修复
有些服务器被植入木马后门,即使重启服务器也还是被攻击,木马会自动启动,检查linux的init.d的文件夹里是否有多余的启动文件,也可以检查时间,判断启动项是否有问题
在被攻击时尤其要注意,排查所备份的数据是否也存在攻击源,如果存在就要及时删除,如果查不出是通过哪些方式、哪些渠道进行攻击的,只能重装系统,彻底清除攻击源
在被攻击过后,我们也不能放松警惕,评估服务器的硬防标准是否需要升级,为了安全,建议游戏行业使用高防服务器
