공격 IP 차단
2012.12.02 18:53
무슨 이유인지 모르겠지만 특정 IP(163.19.184.101)로부터 수일간 지속적으로 서버를 공격하는 것이 확인되었습니다.
덕분에 수십기가짜리 경고 로그 파일이 생겼네요... 그 여파로 시스템 디스크 Full로 일부 서비스에 문제가 있었습니다.
공격하는 IP를 확인해 보면 대만 소재 국립대로 확인이 되네요.

별 대응 없이 서버에서 해당 IP를 막아버렸습니다.
혹 이후 같은 IP 대역에서 동일한 공격이 확인되면 해당 대역(163.13.0.0 - 163.32.255.255)을 모두 차단할 예정입니다.
