Security Architecture for Business-Critical Applications
Business-critical apps need security by design. Defense in depth, zero trust, least privilege. Here are the architecture patterns we use.

Table of Contents
Defense in Depth
Multiple layers: WAF, network, app, data. If one fails, others protect. No single point of failure.
Zero Trust
Never trust, always verify. Every request authenticated and authorized. Assume breach.
Least Privilege
Users and services get minimum access needed. RBAC. Regular access reviews.
Security Layers
- Network: WAF, DDoS protection, firewall
- Application: Auth, input validation, secure coding
- Data: Encryption at rest and in transit
- Monitoring: Logs, alerts, incident response
