스마트폰 시장 경쟁 본격화에 따른 개방형 플랫폼 증가와 앱스토어의 등장으로 인하여 범용 OS를 채택하고 있는 모바일 단말은 모바일 악성코드의 제작을 용이하게 만들고, 제작된 모바일 악성코드는 범용 OS로 인해 이식성이 높기 때문에 모바일 공격의 규모 및 피해가 증가할 것으로 예상된다. 따라서 향후 더욱 지능화되고 다양한 형태로 변형될 수 있는 악의적 행위에 의한 정보 유출, 불법 과금, 부정 사용 등과 같은 보안 위협으로부터 스마트폰 사용자를 보호하고, 서비스 환경에 안전성, 무결성, 가용성, 신뢰성을 제공하기 위한 스마트폰 보안 기술 개발이 요구된다. 본 고에서는 스마트폰 보안 위협요소와 모바일 악성코드 동향을 살펴보고 이들 위협에 대응하기 위한 단말 및 모바일 보안 인프라 기술들을 소개하고자 한다.
