Security Guardian

System for automated security auditing and credential protection.

Core Workflows

1. Secret Scanning

Scan specific project directories for hardcoded credentials.

• Tool: scripts/scan_secrets.py
• Usage: python3 $WORKSPACE/skills/security-guardian/scripts/scan_secrets.py <path_to_project>
• Workflow:
  1. Execute scan on a specific project or directory.
  2. If findings are reported (exit code 1):
     • Review the file and line number.

     • Transition: Move the secret to a secure vault (e.g., using the mema-vault skill).
     • Redact: Replace the plaintext secret in the source code with an environment variable or a vault lookup call.

2. Container Vulnerability Scan

Analyze Docker images for vulnerabilities prior to deployment.

• Tool: scripts/scan_container.sh
• Usage: bash $WORKSPACE/skills/security-guardian/scripts/scan_container.sh <image_name>
• Logic: Identify HIGH and CRITICAL severities. Recommend base image updates or security patches.

Security Guardrails

• Scope Limitation: Avoid scanning system-level directories. Focus only on relevant project workspaces.
• Credential Isolation: Hardcoded secrets are considered a high-severity finding.
• Dependencies: Container scanning requires trivy to be installed on the host system.

Integration

• Vaulting: This skill identifies leaks. Remediation should be performed using a dedicated credential manager like mema-vault.

这个 Skill 质量较好，文档清晰、使用方便，能有效帮助检测代码中的密钥泄露和容器漏洞。优点是安全防护意识强，有防误扫机制，支持多种常见密钥类型检测。不足之处是容器扫描功能较简单，依赖外部工具安装，且缺少自动化测试覆盖。整体适合对安全性有一定要求的项目使用。
