안녕하세요.
오랜만에 nginx/access.log 를 봤더니 한 IP에서 저희 서버의 취약점을 찾으려고한 흔적을 발견했습니다.
매일 이런 시도가 있긴 한데 보통 주소 몇번 넣어보고 지나가는데 어떤 놈이 툴까지 써서 싹 훑고 갔더라구요
로그내역은 아래와 같습니다.

이런식으로 phpmyadmin 페이지를 찾으려고 한 흔적이 있습니다.
로그를 보며 의아했던점은, 초당 수십번의 체크를 하고 갔다는 겁니다.
7초만에 650개의 주소를 훑고 갔습니다.
IDC에서 기본적으로 제공하는 IDS도 있고 따로 신청한 IPS도 있고 서버에선 firewalld도 켜져있는데
초당 수십회의 액세스를 시도하는 IP에 대해 어떠한 차단조치가 이루어지지 않은것이 충격적이었습니다.
제가 보안쪽엔 지식이 미천한 관계로 위와 같은 비정상적인 접근(초당 수회 액세스등)을 차단하기 위해선 어떠한 조치를 취할 수 있는지 조언좀 부탁드리겠습니다.

phpmyadmin의 설치경로는 절대 유추할 수 없도록 디렉토리 이름을 변경해두었기 때문에 털리지 않을 수 있었습니다만 등골이 오싹하네요.
