문제는이 URL 히트 모든 시간을 우리 서버는 Wordpress (.htaccess 규칙 참조)로 이동하여 db와 일치하는 페이지를 검색합니다. 이것은 아파치가 segfault하는 원인이되는 불필요한 스파이크를 일으키고 있습니다.

어떻게하면이 URL이 Wp를 공격하지 못하게 할 수 있습니까? 규칙이 일치 할 때

Answer 1

F 플래그는 403 Forbidden 응답을 보냅니다 :

RewriteRule /w00tw00t\.at\.ISC\.SANS\.DFind - [F] 

그냥 RewriteBase / 후이를 추가합니다.

BTW의 [error] client sent HTTP/1.1 request without hostname 오류는 아파치가 400 Bad request 상태로 회신하고 이러한 요청이 wordpress를 공격하지 않는다고 제안합니다.

Answer 2

iptables를 통해 이러한 종류의 액세스를 차단하고 싶지 않을 수 있습니다. ssh를 통해 루트 계정으로 서버에 가서 다음을 입력하십시오.

iptables -I INPUT -p tcp --dport 80 -m string --to 60 --algo bm --string 'GET /w00tw00t' -j DROP
