Zero Trust
Never trust, always verify. Moving security from the network perimeter to the identity of every workload and user.
Identity is the New Perimeter
Traditional security relied on a castle and moat strategy: once you were inside the VPN, you were trusted. In a cloud-native world with remote employees and distributed microservices, the perimeter has dissolved.
My approach to Zero Trust ensures that every request whether from a user or a service is authenticated, authorized, and encrypted. We assume the network is hostile.
Service Mesh Implementation
Implementing a Service Mesh is the most effective way to enforce Zero Trust in a microservices architecture.
- ●mTLS (Mutual TLS): Automatically encrypts traffic between services and validates identity. Service A cannot talk to Service B without a valid certificate.
- ●Traffic Control: Fine-grained allow/deny rules ("The frontend can call the Product API, but cannot call the Billing API directly").
- ●Observability: Gaining deep visibility into traffic flow to detect anomalies or unauthorized access attempts.
Holistic Security
User Identity
Context-aware access via IDPs. MFA is mandatory. Access depends on device health and location.
Least Privilege
IAM Roles for clouds services are scoped to the absolute minimum permissions required for the task.
Secrets Management
No hardcoded credentials. Secrets are injected at runtime and rotated automatically.
