Blueberry IDP Security Guide

This guide provides comprehensive security documentation for the Blueberry Internal Developer Platform, covering policies, procedures, and best practices.

🔒 Security Overview

The Blueberry IDP implements a defense-in-depth security model with multiple layers of protection:

• Authentication: Firebase Auth + API tokens
• Authorization: RBAC + namespace isolation
• Network Security: Kubernetes network policies
• Data Protection: Encryption at rest and in transit
• Secret Management: Google Secret Manager integration
• Audit Logging: Comprehensive activity tracking

🎯 Security Principles

Defense in Depth

Multiple independent layers of security controls:

1. Perimeter Security
2. Cloud Load Balancer with SSL termination
3. Ingress controllers with rate limiting

4. DDoS protection

5. Network Security

6. VPC isolation
7. Kubernetes network policies

8. Service mesh (future)

9. Application Security

10. Authentication and authorization
11. Input validation

12. Secure coding practices

13. Data Security

14. Encryption at rest (Firestore, Secret Manager)
15. Encryption in transit (TLS 1.3)
16. Data classification

Zero Trust Architecture

Never trust, always verify:

• Identity Verification: Every request authenticated
• Device Trust: No implicit network trust
• Continuous Validation: Dynamic access decisions
• Least Privilege: Minimal access by default

Least Privilege Access

Minimal permissions required for function:

• Just-in-Time Access: Temporary privilege escalation
• Regular Reviews: Periodic access audits
• Automated Provisioning: Consistent permission management
• Time-bound Access: Automatic deprovisioning

🛡️ Security Controls

Authentication

Authorization

Data Protection

🔧 Security Configuration

Environment Isolation

Each environment runs in isolated namespace with:

# Network Policy - deny all by default
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: deny-all
  namespace: environment-namespace
spec:
  podSelector: {}
  policyTypes:
  - Ingress
  - Egress

Secret Management

Secrets are managed through External Secrets Operator:

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: app-secrets
spec:
  secretStoreRef:
    name: gcpsm-secret-store
    kind: SecretStore
  target:
    name: app-secrets
    creationPolicy: Owner
  data:
  - secretKey: database-password
    remoteRef:
      key: database-password

RBAC Configuration

Role-based access control for API resources:

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: environment-namespace
  name: environment-manager
rules:
- apiGroups: [""]
  resources: ["pods", "services", "configmaps"]
  verbs: ["get", "list", "watch"]
- apiGroups: ["apps"]
  resources: ["deployments"]
  verbs: ["get", "list", "watch", "create", "update", "patch"]

📊 Security Monitoring

Audit Events

Key security events to monitor:

• Authentication attempts (success/failure)
• API token creation/revocation
• Environment creation/deletion
• Secret access patterns
• Permission changes
• Failed authorization attempts

Alerting

Critical security alerts:

# Example alert for failed authentication
- alert: HighFailedAuthentication
  expr: increase(auth_failures_total[5m]) > 10
  for: 2m
  labels:
    severity: warning
  annotations:
    summary: "High number of authentication failures"
    description: "{{ $value }} authentication failures in 5 minutes"

Metrics

Security metrics to track:

• Authentication success rate
• API token usage patterns
• Environment access frequency
• Secret rotation compliance
• Certificate expiration dates

🚨 Incident Response

Security Incident Classification

Response Procedures

1. Detection: Automated alerts or manual discovery
2. Assessment: Determine impact and severity
3. Containment: Isolate affected systems
4. Investigation: Root cause analysis
5. Recovery: Restore normal operations
6. Lessons Learned: Post-incident review
