# AWS with access keys
lock-and-key scan --provider AWS --access-key YOUR_KEY --secret-key YOUR_SECRET --region us-east-1

# Azure (in progress)
lock-and-key scan --provider Azure --client-id YOUR_ID --secret YOUR_SECRET --tenant-id YOUR_TENANT

# GCP (in progress)
lock-and-key scan --provider GCP --creds-path /path/to/service-account.json

Options

• --output-dir: Specify output directory for reports (default: ./reports)
• --provider: Choose cloud provider (AWS, Azure, GCP)
• Various credential options for each provider

Security Checks

Lock & Key identifies the following security issues:

• Administrative Permissions: Policies with *:* actions
• Wildcard Resources: Policies allowing access to all resources (*)
• Privilege Escalation: IAM permissions that could lead to privilege escalation
• Overly Broad Access: Resource policies with excessive permissions
• Cross-Account Access: Policies allowing external account access

Report Format

Reports are generated in JSON format with the following structure:

{
  "provider": "AWS",
  "account_id": "123456789012",
  "issues_found": 15,
  "least_privilege_violations": 8,
  "high_risk_permissions": 3,
  "summary": "Scanned IAM and all resource policies. Found 15 security issues.",
  "findings": [
    {
      "resource_name": "MyPolicy",
      "resource_id": "arn:aws:iam::123456789012:policy/MyPolicy",
      "issue_type": "Excessive Permissions",
      "severity": "High",
      "description": "Administrative permissions (*:*) detected",
      "recommendation": "Replace wildcard permissions with specific actions"
    }
