다음은 내 Netgear 6300 라우터에서 필터링된 2일 간의 로그입니다. SMURF 공격이 지속적으로 발생하는 것 같습니다.
내 라우터 설정에 따르면 보호받고 있는 것 같습니다. "포트 스캔 및 DoS 보호 비활성화"가 선택되어 있지 않습니다.
걱정해야 할까요?

답변1
스머프:
작은 단위로 개체로부터 받거나 개체에게 주는 것입니다.
메스암페타민을 만들기 위해 마약 요리사는 "스머프"를 고용하여 충분할 때까지 하루에 애드빌 감기약과 부비동염 약 2박스를 구입합니다.
(분산)DoS 공격:
서버에 과부하가 걸리고 다운되어 합법적인 목적으로 서버에 연결하는 모든 사람에 대한 서비스를 "거부"하는 것입니다.
누군가 매우 천천히 귀하의 모든 대역폭을 빼앗아 충돌을 시도하고 있습니다.. 무언가. 웹 서버를 운영하시나요? 그렇지 않은 경우 맬웨어가 봇넷 종류의 일부로 컴퓨터를 천천히 DoS 작업으로 만들 가능성이 있습니다.
