공인 IP에 연결된 장비에는 다양한 공격시도가 들어오곤 합니다.

http://joshaven.com에서는 MikroTik 장비용으로 IP reputation 정보를 address list로 만들어 종종 업데이트 해주곤 하는데, 이를 이용하여 방화벽에서 걸러주면 공인 IP에 노출된 MikroTik장비 혹은 MikroTik 장비의 하단에 노출된 장비로의 부정 접근 시도를 완벽하지는 않지만 어느정도 줄여줄 수 있습니다.


http://joshaven.com 에서 제공하는 리스트에는 몇 가지가 있습니다. 필요하다 싶은 것만 선택해서 사용하시면 됩니다.(2011급 이상 장비에서 사용을 권장합니다.)


1. OpenBL(FTP, SSH, TELNET, SMTP, POP3, IMAP, Submission, IMAPS, POP3S, HTTP, HTTPS에 대한 bruteforce 대입시도 호스트 리스트)

http://www.openbl.org/lists/base_30days.txt.gz

아래 스크립트를 입력합니다. 스케쥴러에 의하여 3일마다 업데이트 됩니다.(차단 혹은 기타 조치를 위해서는 방화벽에서 'blacklist' 라는 이름의 address list를 차단 혹은 기타 조취를 취해주면 됩니다. 이하 모든 스크립트로는 address list 만 업데이트 됩니다.)
