Abstract

소스 코드에 암호 데이터베이스를 저장하는 것은 좋은 방법이 아닙니다. 암호화하더라도 이 방법을 사용하면 몇 가지 위험에 노출될 수 있습니다.

Explanation

암호 데이터베이스는 암호 및 기타 민감한 정보를 저장하기 위한 암호화된 데이터베이스입니다. 암호 데이터베이스를 소스 코드와 함께 저장하는 데는 몇 가지 문제가 있습니다.

1. 조직에서 데이터베이스에 사용되는 마스터 암호의 강도를 제어할 수 있는 방법이 없으므로 약한 암호를 사용할 수 있습니다.

2. 암호 데이터베이스를 사용하여 팀 구성원 간에 암호를 공유하면 누구나 자격 증명이 있는 서비스에 익명으로 액세스할 수 있으므로 조직이 내부 위협에 노출됩니다. 팀 구성원이 조직을 떠날 때 모든 공유 암호를 변경해야 하므로 떠나는 구성원의 개인 계정을 비활성화하는 것보다 훨씬 더 많은 시간이 소요됩니다.

3. 암호 데이터베이스가 제공된 제품과 암호를 번들로 사용하는 경우 모든 고객에게 동일한 암호를 사용하거나 각 고객에 대해 고유한 암호를 생성하기 위해 복잡한 논리가 필요할 수 있습니다. 어느 쪽이든 고객을 위험에 노출시킵니다.

4. git와 같은 버전 제어 시스템을 사용하는 경우 이전 버전 암호 데이터베이스에 대한 공격에 취약할 수 있습니다. 이전 버전은 약한 암호가 사용되었거나 안전하지 않은 암호 데이터베이스를 생성했을 수 있는 이전 버전의 암호 관리 소프트웨어가 사용되었을 때부터 존재할 수 있습니다.

5. 소스 코드 디렉터리에 암호 데이터베이스를 저장하면 고객에게 배송되는 빌드된 아티팩트에 실수로 포함될 위험이 높아집니다.

암호 데이터베이스가 유출되면 암호를 해독하기 위한 무차별 대입 공격에 취약해집니다. 암호화의 강도와 사용된 마스터 키에 따라 위험이 상당히 클 수 있습니다.
