## mobsfscan 구성
소스 코드 디렉터리 루트에 있는 `.mobsf` 파일을 사용하면 mobsfscan을 구성할 수 있습니다. `--config` 인수를 사용하여 사용자 정의 `.mobsf` 파일을 사용할 수도 있습니다.```yaml
---
- ignore-filenames:
- skip.java
ignore-paths:
- __MACOSX
- skip_dir
ignore-rules:
- android_kotlin_logging
- android_safetynet_api
- android_prevent_screenshot
- android_detect_tapjacking
- android_certificate_pinning
- android_root_detection
- android_certificate_transparency
severity-filter:
- WARNING
- ERROR
severity-overrides:
ios_log: ERROR
android_logging: WARNING
severity-overrides는 특정 rule ID(INFO, WARNING, ERROR)에 대해 보고되는 심각도를 변경합니다. Override는 severity-filter 이전에 적용되며 CLI 출력, 종료 코드, 보고서 형식(SARIF, SonarQube, GitLab SAST)에 영향을 줍니다.
발견 사항 억제
발견 사항을 트리거하는 줄에 // mobsf-ignore: rule_id1, rule_id2 주석을 추가하여 소스 파일의 발견 사항을 억제할 수 있습니다. 해당 일치 항목만 억제되며, 파일 내 동일한 규칙의 다른 일치 항목은 여전히 보고됩니다.
예시:```java String password = "strong password"; // mobsf-ignore: hardcoded_password
## CI/CD 통합
CI/CD 또는 DevSecOps 파이프라인에서 mobsfscan을 활성화할 수 있습니다.

#### Gitlab CI/CD
`.gitlab-ci.yml` 파일에 다음을 추가하세요.```yaml
stages:
- test
mobsfscan:
image: python:3.12
stage: test
before_script:
- pip3 install --upgrade mobsfscan
script:
- mobsfscan . --gitlab-sast -o gl-sast-report.json
artifacts:
reports:
sast: gl-sast-report.json
예시 명령(로컬):```bash mobsfscan . --gitlab-sast -o gl-sast-report.json
이것은 네이티브 [GitLab SAST 보고서](https://docs.gitlab.com/user/application_security/sast/)를 작성하므로 SARIF 변환기 없이도 취약점 보고서 / MR 보안 위젯에 결과가 나타납니다.
#### SonarQube / SonarCloud
`--sonarqube`는 [일반 이슈 형식](https://docs.sonarsource.com/sonarqube-server/analyzing-source-code/importing-external-issues/generic-issue-import-format)(SonarQube 10.3+ / SonarCloud)을 작성하며, `rules`와 `issues` 배열이 분리되어 있습니다:```bash
mobsfscan . --sonarqube -o mobsfscan-sonar.json
sonar.externalIssuesReportPaths=mobsfscan-sonar.json로 가져옵니다.
Travis CI
.travis.yml 파일에 다음을 추가합니다.```yaml
language: python
install:
- pip3 install --upgrade mobsfscan
script:
- mobsfscan .
#### Circle CI
`.circleci/config.yaml` 파일에 다음을 추가하세요.```yaml
