우리는 최근 몇 년 동안 바이러스, 웜, 트로이얀, 스파이웨어와 같은 사이버 공격들이 인터넷 상에서 점점 증가하고 있음을 목격해 왔다. 이런 사이버 공격들은 인터넷 사용의 효율성을 저해하고 있고, 수 분내로 대규모 네트워크 망을 전복시킬 정도로 IT 인프라의 위협이 되고 있다. 기존의 보안 시스템 및 인프라들은 알려지지 않은 새로운 사이버 공격들에 대해 사람의 분석을 통한 대응을 해 왔다. 그러나 이런 방식은 즉각 적인 대응이 필요한 상황에서는 종종 그 효율성이 떨어지기 때문에 공격 탐지와 대응을 위한 자동화된 방식에 대한 연구가 중요한 이슈가 되었다. 본 고에서는 알려지지 않은 신종 사이버 공격을 탐지하고 차단하기 위한 인프라 구축에 대한 최근의 대규모 프로젝트들을 소개하려고 한다.
