ZERO-TRUST ARCHITECTURE FOR MODERN SAAS PLATFORMS
Why the network perimeter is dead and how to implement identity-based security at every layer.
The Death of the Firewall
The "castle and moat" model of security is obsolete. In a world of remote work and multi-cloud, there is no "inside." Zero-Trust architecture assumes the network is already compromised and requires strict verification for every single request, regardless of where it originates.
Identity is the New Perimeter
Instead of trusting an IP range, we trust cryptographic identities. Every service in our mesh has its own identity (SPIFFE-compliant) and must present a valid certificate to talk to another service.
Data Encryption at Rest and in Transit
Encryption isn't optional. Use KMS (Key Management Service) to manage rotating keys and ensure that even if your database backups are stolen, they are useless without the keys stored in a hardware security module.
The Principle of Least Privilege
Does your web-server really need DROP TABLE permissions? Of course not. Grant only the absolute minimum permissions required to perform a task.
Continuous Monitoring and Response
Security is a process, not a state. Implement automated scanning (SAST/DAST) in your CI/CD pipeline and use eBPF-based tools to monitor system calls for suspicious behavior in production.
Never trust, always verify every request.
Least-privilege access should be the default for all services.
mTLS (Mutual TLS) is the gold standard for service-to-service auth.
Implement Just-In-Time (JIT) access for administrative tasks.
Secrets management belongs in Vault, not environment variables.
Audit logs must be immutable and centralized.
