cloudguard

Cloud infrastructure & IaC security scanner -- detects insecure Terraform, open S3 buckets, permissive IAM, missing encryption, exposed ports, and cloud misconfigurations

CloudGuard -- Cloud Infrastructure & IaC Security Scanner

CloudGuard scans codebases for insecure cloud infrastructure patterns including Terraform misconfigurations, open S3 buckets, overly permissive IAM policies, missing encryption at rest, exposed ports, absent logging and monitoring, and general cloud compliance gaps. It uses 90 regex-based patterns across 6 security categories, produces severity-graded reports with actionable remediation, and integrates with git hooks via lefthook. 100% local. Zero telemetry.

Commands

Free Tier (No license required)

cloudguard scan [file|directory]

One-shot cloud security scan of infrastructure-as-code files or directories.

How to execute:

bash

bash "<SKILL_DIR>/scripts/dispatcher.sh" --path [target]

What it does:

1. Accepts a file path or directory (defaults to current directory)
2. Discovers all IaC and configuration files (Terraform .tf, CloudFormation .yml/.yaml/.json, Dockerfiles, Kubernetes manifests, cloud config files)
3. Runs 30 cloud security patterns against each file (free tier limit)
4. Skips .git, node_modules, .terraform, vendor, and other non-IaC directories
5. Respects .gitignore and allowlist files
6. Calculates a cloud security score (0-100) per file and overall
7. Grades: A (90-100), B (80-89), C (70-79), D (60-69), F (<60)
8. Outputs findings with: file, line number, check ID, severity, category, description, recommendation
9. Exit code 0 if score >= 70, exit code 1 if score < 70 (too many misconfigurations)
10. Free tier limited to first 30 of 90 patterns

Example usage scenarios:

• "Scan my Terraform for security issues" -> runs cloudguard scan .
• "Check my cloud config for misconfigurations" -> runs cloudguard scan infra/
• "Audit my AWS infrastructure code" -> runs cloudguard scan terraform/
• "Find open S3 buckets in my IaC" -> runs cloudguard scan .

Check Categories

CloudGuard detects 90 cloud security patterns across 6 categories:

Category	Code	Patterns	Examples	Severity Range
Storage Security	S3	15	Public S3 buckets, missing encryption, no versioning, overly permissive bucket policies, missing access logging, no lifecycle rules	Critical/High/Medium
IAM & Permissions	IM	15	Wildcard IAM policies, AdministratorAccess, overly broad assume role, missing MFA, root account usage, no least privilege	Critical/High/Medium
Network Security	NW	15	Open security groups (0.0.0.0/0), exposed ports (22, 3389, 3306), missing VPC, no network ACLs, public subnets without NAT, SSH open to world	Critical/High/Medium
Encryption	EN	15	Missing encryption at rest, no KMS key rotation, unencrypted EBS volumes, missing SSL/TLS, no transit encryption, weak cipher suites	Critical/High/Medium/Low
Logging & Monitoring	LG	15	Missing CloudTrail, no VPC flow logs, disabled GuardDuty, missing alarm configurations, no SNS notifications, absent audit logs	High/Medium/Low
Configuration & Compliance	CF	15	Missing tags, no resource naming convention, hardcoded regions, missing backups, no disaster recovery, drift detection gaps	Medium/Low

Severity Levels

Level	Points Deducted	Meaning	Action Required
Critical	25	Immediate infrastructure compromise risk (open to internet, no auth, wildcard admin)	Fix immediately; block deployment
High	15	Significant security gap that could be exploited (missing encryption, overly permissive policies)	Fix within current sprint
Medium	8	Security best practice violation that increases attack surface	Plan remediation within 30 days
Low	3	Informational finding, minor hygiene issue, or hardening recommendation	Address when convenient

Scoring System

CloudGuard uses a 0-100 scoring system:

• Starting score: 100 (perfect, no findings)
• Deductions: Each finding deducts points based on severity
• Floor: Score cannot go below 0
• Pass threshold: 70 (exit code 0)
• Fail threshold: Below 70 (exit code 1)

Grade Scale

Grade	Score Range	Meaning
A	90-100	Excellent -- minimal or no cloud security issues
B	80-89	Good -- minor issues that should be addressed
C	70-79	Acceptable -- passing but needs improvement
D	60-69	Poor -- significant security gaps requiring attention
F	Below 60	Failing -- critical misconfigurations must be fixed immediately

Tier-Based Pattern Access

Tier	Patterns Available	Categories
Free	30 patterns	First 5 patterns per category
Pro	60 patterns	First 10 patterns per category
Team	90 patterns (all)	All 15 patterns per category
Enterprise	90 patterns (all)	All 15 patterns per category + priority support

Configuration

Users can configure CloudGuard in ~/.openclaw/openclaw.json:

json

{
  "skills": {
    "entries": {
      "cloudguard": {
        "enabled": true,
        "apiKey": "YOUR_LICENSE_KEY_HERE",
        "config": {
          "severityThreshold": "high",
          "ignorePatterns": ["**/test/**", "**/examples/**", "**/fixtures/**"],
          "ignoreChecks": [],
          "reportFormat": "text",
          "categories": ["S3", "IM", "NW", "EN", "LG", "CF"]
        }
      }
    }
  }
}

Supported File Types

CloudGuard scans the following file types for cloud security patterns:

File Type	Extensions	Use Case
Terraform	.tf, .tfvars	HashiCorp Terraform IaC definitions
CloudFormation	.yml, .yaml, .json, .template	AWS CloudFormation templates
Kubernetes	.yml, .yaml	Kubernetes manifests and Helm charts
Docker	Dockerfile, docker-compose.yml	Container configurations
Ansible	.yml, .yaml	Ansible playbooks and roles
General Config	.conf, .cfg, .ini, .toml, .hcl	Infrastructure configuration files
Scripts	.sh, .bash, .ps1, .py	Deployment and provisioning scripts
Policy	.json, .rego	IAM policies, OPA Rego rules

Important Notes

• Free tier works immediately with no configuration
• All scanning happens locally -- no code is sent to external servers
• License validation is offline -- no phone-home or network calls
• Pattern matching only -- no AST parsing, no external dependencies beyond bash and grep
• Supports scanning all IaC file types in a single pass
• Git hooks use lefthook which must be installed (see install metadata above)
• Exit codes: 0 = pass (score >= 70), 1 = fail (score < 70, for CI/CD integration)
• Category-level breakdown shows exactly where security gaps exist

Error Handling

• If lefthook is not installed and user tries hooks install, prompt to install it
• If license key is invalid or expired, show clear message with link to https://cloudguard.pages.dev/renew
• If a file is binary, skip it automatically with no warning
• If no scannable IaC files found in target, report clean scan with info message
• If invalid category specified with --category, show available categories
• If grep does not support -E flag (rare), fall back gracefully with error message
