모범 사례
보안
- 항상 보안 API 토큰으로 인증 (토큰을 커밋하지 않음)
- 프로덕션 CI/CD에서
--severity-threshold=critical사용 - Snyk CLI를 최신 버전으로 정기적으로 업데이트
- 자동 수정을 검토하고 병합 전에 승인
.snyk정책 파일을 버전 제어에 포함- 일관성을 위해 조직 수준의 정책 사용
snyk monitor로 취약점을 지속적으로 모니터링
성능
- CI/CD에서
--quiet플래그를 사용하여 출력 감소 - 가능하면 실행 간에 의존성 캐싱
- 모든 이미지가 아닌 특정 태그에서 컨테이너 스캔 실행
- 수정 불가능한 문제를 건너뛰기 위해
--skip-unresolved사용 - 심각도별로 필터링하여 실행 가능한 문제에 집중
- 가능하면 영향을 받는 경로만 스캔
워크플로우
- PR 확인에 통합하여 안전하지 않은 코드의 병합 방지
snyk fix를 사용하여 패칭 자동화- 커밋하기 전에
snyk ignore결정 검토 - 지속적 추적을 위해
snyk monitor사용 - 새로운 취약점에 대한 경고 설정
- 이유와 만료 날짜가 포함된 예외 문서화
- 무시된 취약점의 정기적 검토
