Enterprise Readiness

Enterprise Readiness Assessment

Assess and enhance software projects for enterprise-grade security, quality, and automation.

When to Use

• Evaluating projects for production/enterprise readiness
• Implementing supply chain security (SLSA, signing, SBOMs)
• Hardening CI/CD pipelines
• Establishing quality gates
• Pursuing OpenSSF Best Practices Badge (Passing/Silver/Gold)

Assessment Workflow

1. Discovery: Identify platform (GitHub/GitLab), languages, existing CI/CD
2. Scoring: Apply checklists based on stack
3. Badge Assessment: Check OpenSSF criteria status
4. Gap Analysis: List missing controls by severity
5. Implementation: Apply fixes using templates

Scoring System

Base Score (0-100 points)

Severity Levels

Universal Controls Checklist (60 pts)

Repository Basics (15 pts)

• LICENSE file present (SPDX identifier)
• README.md with project description
• CONTRIBUTING.md with contribution guidelines
• CODE_OF_CONDUCT.md (Contributor Covenant)
• SECURITY.md with vulnerability reporting process

Branch Protection (15 pts)

• Default branch protected
• Require pull request reviews (1+ reviewers)
• Require status checks before merging
• Require signed commits (GPG/SSH)
• No force pushes to protected branches

CI/CD Pipeline (15 pts)

• Automated tests on every PR
• Linting and static analysis
• Dependency vulnerability scanning
• Build verification
• Coverage reporting

Security Practices (15 pts)

• Dependabot or Renovate enabled
• Secret scanning enabled
• CodeQL or similar SAST
• No secrets in repository
• Signed releases

GitHub-Specific Controls (40 pts)

Security Features

• Secret scanning enabled
• Push protection enabled
• Dependabot security updates
• CodeQL analysis
• Private vulnerability reporting

Actions Security

• Actions pinned by SHA (not tag)
• Minimal permissions (least privilege)
• No pull_request_target with untrusted input
• GITHUB_TOKEN scoped appropriately

Example: Secure Action Reference

# ❌ INSECURE - Tag can be moved
- uses: actions/checkout@v4

# ✅ SECURE - SHA-pinned with version comment
- uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1

SLSA Framework

SLSA Levels

GitHub Actions SLSA Provenance

# .github/workflows/release.yml
name: Release

  push:
    tags:
      - 'v*'

permissions:
  contents: write
  id-token: write
  attestations: write

    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1

        with:
          base64-subjects: ${{ steps.hash.outputs.hashes }}

Signed Releases

Cosign (Containers)

# Sign container image
cosign sign --key cosign.key myregistry/myimage:v1.0.0

# Verify signature
cosign verify --key cosign.pub myregistry/myimage:v1.0.0

GPG (Git Tags)

# Sign tag
git tag -s v1.0.0 -m "Release v1.0.0"

# Verify tag
git tag -v v1.0.0

Software Bill of Materials (SBOM)

Generate SBOM

# Using Syft
syft packages . -o spdx-json > sbom.spdx.json

# Using CycloneDX for PHP
composer require --dev cyclonedx/cyclonedx-php-composer
composer make-bom

SBOM in CI

- name: Generate SBOM
  uses: anchore/sbom-action@v0
  with:
    artifact-name: sbom.spdx.json

Security Hardening

Content Security

# _headers or .htaccess
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Content-Security-Policy: default-src 'self'
Strict-Transport-Security: max-age=31536000; includeSubDomains

Input Validation

// ✅ SECURE - Validate and sanitize all input
$email = filter_var($input, FILTER_VALIDATE_EMAIL);
if ($email === false) {
    throw new ValidationException('Invalid email');
}

Score Interpretation

Critical Rules

• NEVER interpolate ${{ github.event.* }} in run: blocks (script injection)
• NEVER guess action versions - fetch from GitHub API or documentation
• ALWAYS use SHA pins for actions with version comments
• ALWAYS verify commit hashes against official tags
• NEVER store secrets in code or commit history

Resources

• OpenSSF Scorecard
• Best Practices Badge
• SLSA Framework
• S2C2F
• Sigstore
