# SLSA3 Configuration
version: 1.0
compliance:
  level: 3
  requirements:
    - build_service
    - provenance
    - source_integrity
    - security_scanning

build:
  service: github_actions
  isolation: container
  ephemeral: true

provenance:
  format: in-toto
  version: 0.2
  signer: github_oidc

security:
  scanning:
    - trivy

Usage Instructions

1. Save the workflow as .github/workflows/slsa3-publish.yml

2. Required Secrets: ```bash # For enhanced security, add these to your repository secrets:

   • COSIGN_PRIVATE_KEY # For artifact signing
   • SLSA_SIGNING_KEY # For provenance signing

3. Trigger the workflow: bash # Create a release tag git tag v1.0.0 git push origin v1.0.0

4. Verify compliance: bash chmod +x verify-slsa3.sh ./verify-slsa3.sh

This SLSA3 publish workflow provides:

• ✅ SLSA Level 3 compliance with provenance generation
• ✅ Multi-platform builds (Linux, Windows, macOS)
• ✅ Security scanning with Trivy and dependency review
• ✅ Container image building with provenance
• ✅ SBOM generation in SPDX format
• ✅ Artifact signing with Cosign
• ✅ Comprehensive verification
• ✅ Compliance reporting
• ✅ Notification system

The workflow automatically generates all required attestations and ensures your releases meet SLSA Level 3 security standards.

CodeAnt-AI Description

Add Firebase security rules, authentication checks, App Check, and monitoring examples

What Changed

• Added a new .devcontainer file that contains a complete Firebase security setup: hosting headers, emulator ports, and configuration samples.
• Added Firestore rules that require authentication for reads/writes, restrict user documents so users can only access their own data, enforce author-only edits for posts and comments, provide admin-only access to admin collections, and create an audit collection with admin read access.
• Added Storage rules that limit uploads to each user's folder, allow profile picture writes only by the owner, permit post images only when the post exists and the uploader is the post author, and make a public folder read-only except for admins.
• Added client-side authentication code that enforces email verification, applies session expiration (sign-out after stale sessions), sets session persistence, enforces strong password rules at signup, and logs security events for sign-in/sign-up failures and successes.
• Added App Check example (reCAPTCHA v3) to protect API calls.
• Added Cloud Functions that monitor audit logs for repeated failed logins (and create security alerts) and a scheduled job to delete old audit logs.
• Added security best-practice utilities: file upload validation (max 5MB, allowed types), basic input sanitization, secure token generation, and an environment variable example.
• Included usage examples showing how to register users securely and validate file uploads so clients will reject insecure inputs before attempting uploads.

Impact

✅ Fewer unauthorized data reads
✅ Fewer unauthorized file uploads
✅ Shorter detection of suspicious login activity

Suggestion: Fix the session-age check and use the imported modular signOut function instead of calling signOut as a method on this.auth; the comment says "less than 1 hour" but the code checks 24 hours and calls this.auth.signOut() which will fail in the modular SDK — change the threshold to 1 hour and call signOut(this.auth). [possible bug]

Suggested change

	const timeDiff = (currentTime - new Date(tokenTime)) / (1000 * 60 * 60);
	if (timeDiff > 24) {
	await this.auth.signOut();
	throw new Error('Session expired. Please sign in again.');
	const timeDiff = (currentTime - new Date(tokenTime)) / (1000 * 60 * 60); // hours
	if (timeDiff > 1) {
	await signOut(this.auth);
	throw new Error('Session expired (last sign-in over 1 hour). Please sign in again.');

Why Change? ⭐

The current code calls this.auth.signOut() which is incorrect when using the modular Firebase Auth SDK (the imported signOut function should be used), so the suggestion fixes an actual runtime error. It also points out an inconsistency between the comment ("less than 1 hour") and the code (24 hours) — adjusting the threshold is a behavioral decision but aligning comment and code or fixing the check to the intended 1-hour policy is sensible for session security.

🔒 No security issues identified

⚡ Recommended areas for review Missing App import / AppCheck runtime error The App Check snippet calls initializeAppCheck(app, ...) but app is not defined or imported in that snippet. This will cause a runtime crash and disable App Check protection. Also the ReCAPTCHA site key is hard-coded instead of using a runtime-configured secret. Client-side audit logging & IP handling logSecurityEvent builds a security/audit object on the client and logs it to console; getClientIP returns a placeholder. Relying on client-side logs for security/audit is unreliable and can leak sensitive data to client consoles. Audit events should be sent server-side (Cloud Function) with strict write rules and not be relied on from unauthenticated clients.

Suggestion: Replace the overly-permissive global catch-all rule with a safe default deny so only collection-specific rules control access. [security]

[codeant-ai]

Suggestion: Align the session-age enforcement with the comment by enforcing a 1-hour threshold and defensively handle a missing or invalid user.metadata.lastSignInTime. [possible bug]
