소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.
Insecure Transport: Cipher Suite Downgrade
Abstract
응용 프로그램이 클라이언트 암호 집합을 기본 설정으로 지정했습니다.
Explanation
암호 집합은 보안 통신을 설정하는 데 사용되는 알고리즘 집합입니다. 서버와 클라이언트 간에 연결을 설정하는 동안 서버는 상호 지원되는 암호 집합 중에서 어떤 것을 사용할지 결정합니다. 서버와 클라이언트는 지원되는 암호 집합이 다를 수 있습니다. 일반적으로 이전 암호 집합은 권장되지 않으며 응용 프로그램에 보안 취약성이 발생할 수 있습니다. 알려진 보안 취약성이 없는 강력한 암호 집합을 사용하는 것이 일반적으로 권장됩니다.
예제 1: 다음 코드는
Config.PreferServerCipherSuites 필드는 서버가 클라이언트 또는 서버의 암호 집합 기본 설정을 따르는지 여부를 제어합니다. 선택한 암호 집합에 알려진 취약성이 있는 경우, 클라이언트의 기본 암호 집합을 사용하면 보안 취약성이 발생할 수 있습니다.예제 1: 다음 코드는
PreferServerCipherSuites 필드를 false로 설정합니다.
conf := &tls.Config{
PreferServerCipherSuites: false,
}
