많은 기업이 JavaScript를 Backend로 사용하면서(Node.js)
ISMS 인증 심사 시 해당 언어에 대한 SecureCoding 에 대한 가이드 및 보안 취약점 조치 방법 관련문서가 마련되지 않은 경우
결함으로 지적하는 사례가 많이 늘고 있습니다.
이에 참고할 만한 가이드가(JavaScript 시큐어코딩 가이드) KISA에 누리집에 안내되어 있어 해당 가이드를 공유합니다.
해당 가이드에는 VanillaJS , ReactJS , ExpressJS 개발 시 에 대한 안전한 시큐어 코딩 예시가 명시되어 있습니다.
관련자 분들께서는 업무에 참고하시어 SecureCoding 적용 시 도움이 되셨으면 좋겠습니다.
