我有这样的httpd日志信息,它会一直持续下去.首先,这是否意味着我有病毒？我的服务器是僵尸网络的一部分？我的服务器是
Linux Centos 5.
tail -f / var / log / httpd / access_log
另外我怎么能阻止这次袭击？
如何确保我的服务器不发送请求？
我可以添加哪些其他安全措施？

解决方法
I have httpd log information as such which goes on and on forever.
Firstly,does this mean I have a virus? is my server part of a botnet?
您似乎没有病毒,也不可能是僵尸网络的一部分.这两种情况都不希望通过记录他们的活动来宣布他们的存在.
Also how can I block this attack?
这不是攻击.您似乎正在运行开放代理服务器.如果您不需要运行代理服务器,请在Apache配置中禁用代理访问.
How can I make sure my server is not sending out requests?
您的服务器正在发送请求.通过在Apache配置中为代理请求添加ACL来阻止代理访问.这样的事情应该允许从localhost和专用网络块进行代理访问.根据需要调整最后一个允许线.
<Proxy *>
Order deny,allow
Deny from all
Allow from 127.0.0.0/255.0.0.0 ::1/128
Allow from 192.168.2.0/24
</Proxy>
What other security measures can I add?
如果您不需要向Internet主机提供Web服务,请向Apache服务器添加类似于上述的ACL.考虑使用iptables阻止传入的Web请求.
如果您确实需要代理,请考虑使用具有适当访问控制的专用代理,如squid.您还可以在不同的端口上创建单独的虚拟主机以进行代理.这应该有适当的访问控制.
