최저가 서버호스팅 제공 : 85,000원/월

mod_security 웹방화벽을 가동하고 있습니다.
집에서 서버를 돌리고 있고요. 무료 호스팅을 하고 있습니다.
공유기에 물려 돌리고 있습니다. 공유기 주소는 192.168.0.254입니다.
갑자기 공유기에 심하게 렉이 걸리며 서버 뿐만 아니라 데스크탑까지 인터넷이 제대로 안 되
는 현상이 나타나서 서버 로그를 분석해 보았습니다.
예전에 크래킹을 당한 적이 있습니다. 같은 계정으로 계속 침입 시도가 들어오더군요.

 

 


우선 mod_security에 의해 필터링 정책에 걸린 침입 흔적 로그를 보여 드립니다.

ps -ef  명령어로 프로세스를 검사하면 아래와 같이 요상한 것들이 지금도 나오네요.
