Security Best Practices

🔐 Introduction

Configuration files often contain sensitive environment variables, API keys, database credentials, and feature flags. Mishandling them can lead to data breaches, service outages, or compliance violations. App Config.json is built on a zero-trust architecture, but proper implementation on your side is critical.

📖 Core Principle

Treat every configuration key as potentially sensitive. Apply least-privilege access, encrypt at rest and in transit, and rotate secrets regularly.

🛡️ Authentication & Access Control

Strict identity management is the first line of defense. Implement role-based access control (RBAC) and enforce multi-factor authentication (MFA) across all team accounts.

Recommended RBAC Structure

Admin: Full access to settings, billing, and user management. Limit to 2-3 senior engineers.
Editor: Can create, modify, and deploy configurations. Cannot change security policies or billing.
Viewer: Read-only access for auditors, QA teams, or external partners.
Service Accounts: Machine-to-machine tokens with environment-scoped permissions and short expiry.

                        JSON Example
                        {
                          "rbac": {
                            "enable_mfa": true,
                            "session_timeout": "1h",
                            "ip_whitelist": ["192.168.1.0/24", "10.0.0.0/8"],
                            "sso_provider": "okta"
                          }
                        }
                    

🔒 Encryption Standards

All data handled by App Config.json is encrypted using industry-standard protocols. You should verify and enforce these settings in your dashboard.

At Rest: AES-256-GCM with per-tenant encryption keys. Keys are rotated automatically every 90 days.
In Transit: TLS 1.3 enforced for all API and dashboard connections. HSTS is enabled by default.
Client-Side: Optional end-to-end encryption for highly sensitive secrets using your own public key.

⚠️ Important

Never downgrade TLS versions in your SDK initialization. Always verify certificate pinning in mobile or edge deployments.

🗝️ Secret Management & Masking

Secrets should never be treated as plain configuration. Use our dedicated secret vault with automatic masking in logs, UI, and API responses.

Best Practices

Prefix all sensitive keys with `SECRET_` or `KEY_` for automatic vault routing.
Enable Dynamic Rotation for database passwords and API tokens.
Use Secret Scanning in your repository to prevent accidental commits.
Never log raw configuration payloads in your application servers.

                        SDK Usage
                        // Automatic masking enabled by default
                        const config = await AppConfig.load({
                          environment: "production",
                          mask_secrets: true,
                          vault_provider: "aws_secrets_manager"
                        });
                    

📜 Audit Logging & Compliance

Every configuration change, access attempt, and deployment event is immutably logged. Enable real-time streaming to your SIEM for compliance monitoring.

Log retention: Minimum 1 year (Enterprise: 7 years)
Event types: `CONFIG_CREATE`, `CONFIG_UPDATE`, `CONFIG_ROLLBACK`, `AUTH_SUCCESS`, `AUTH_FAIL`, `EXPORT`, `DELETE`
Integrations: Datadog, Splunk, ELK, AWS CloudWatch, Azure Monitor

✅ Compliance Ready

Our audit architecture meets SOC 2 Type II, ISO 27001, HIPAA, and GDPR requirements. Request your compliance pack from the dashboard.

🌐 Environment Isolation

Prevent cross-environment leakage by strictly segmenting your configuration scopes.

Implementation Rules

Never share service account tokens between `dev`, `staging`, and `production`.
Use Environment Prefixes in your SDK to enforce strict boundary checks.
Enable Deploy Gates requiring manual approval or automated testing before production sync.
Isolate third-party integrations (payment, email, analytics) into dedicated config namespaces.

🔄 CI/CD Pipeline Security

Integrate App Config.json into your deployment pipeline securely. Avoid hardcoding tokens in workflow files.

                        GitHub Actions Example
                        name: Sync Config
                        on: [push]
                        jobs:
                          sync:
                            runs-on: ubuntu-latest
                            steps:
                              - uses: actions/checkout@v4
                              - name: Install SDK
                                run: npm i @appconfig/cli
                              - name: Validate & Sync
                                env:
                                  CONFIG_TOKEN: ${{ secrets.CONFIG_TOKEN }}
                                  CONFIG_ENV: production
                                run: appconfig sync --validate --dry-run
                    

💡 Pro Tip

Always run a dry-run validation before applying changes. Use branch protection rules to require config updates to pass automated security scans.

🚨 Incident Response & Rollback

Even with strict controls, mistakes happen. App Config.json provides instant rollback capabilities to mitigate configuration incidents.

Response Protocol

Detect: Monitor error rates and config sync failures via webhooks or SIEM alerts.
Isolate: Disable the affected environment or restrict write access immediately.
Rollback: Use the dashboard or CLI to revert to the last known-good version (`appconfig rollback --version v2.3.1`).
Investigate: Review audit logs to identify the root cause and compromised scope.
Remediate: Rotate affected secrets, update policies, and re-deploy securely.
