Aperçu général

KICS (Keeping Infrastructure as Code Secure) est un outil d'analyse de code statique open source qui détecte les vulnérabilités de sécurité, les problèmes de conformité et les erreurs de configuration de l'infrastructure dans le code Infrastructure. KICS prend en charge Terraform, CloudFormation, Ansible, Kubernetes, Docker, et plus encore, fournissant plus de 2000 requêtes sur plusieurs fournisseurs et plateformes cloud.

C'est-à-dire Caractéristiques principales: 2000+ requêtes de sécurité, support multi-IaC, création de requêtes personnalisées, intégration CI/CD, cadres de conformité (CIS, NIST, OWASP) et rapports complets avec des directives d'assainissement.

fix_common_kics_errors() {
    echo "Common KICS Errors and Solutions"
    echo "==============================="

    cat << 'EOF'
1. "kics: command not found"
   Solution: 
   - Download and install KICS binary
   - Add installation directory to PATH
   - Verify installation with: kics version

2. "failed to load queries"
   Solution:
   - Check queries directory exists
   - Verify query file syntax with OPA
   - Use built-in queries if custom queries fail

3. "timeout exceeded" during scan
   Solution:
   - Increase timeout in config: "timeout": 900
   - Split large directories into smaller chunks
   - Use performance-optimized configuration

4. "out of memory" errors
   Solution:
   - Increase system memory
   - Use chunked scanning for large directories
   - Exclude unnecessary file types and directories
   - Use minimal UI and reduce preview lines

5. "invalid configuration file" error
   Solution:
   - Validate JSON syntax in configuration file
   - Check file permissions
   - Use default configuration as template

6. "no results found" (false negatives)
   Solution:
   - Check file type detection
   - Verify include/exclude filters
   - Use --verbose for detailed output
   - Check severity filters

7. "query execution failed"
   Solution:
   - Validate custom query syntax with OPA
   - Check query metadata format
   - Update to latest KICS version
   - Review query logic and dependencies

8. "permission denied" errors
   Solution:
   - Check file and directory permissions
   - Run with appropriate user privileges
   - Verify write permissions for output directory

9. Slow scanning performance
   Solution:
   - Use optimized configuration
   - Exclude unnecessary paths and file types
   - Reduce log verbosity
   - Use parallel scanning for multiple directories

10. "unsupported file type" warnings
    Solution:
    - Check supported IaC types in documentation
    - Use correct file extensions
    - Specify IaC type explicitly with -t flag
    - Update KICS to latest version for new format support
