Understanding Zero-Trust Security
Zero-Trust Security deviates significantly from traditional security models by not trusting users or devices automatically. Instead, it requires constant identity verification and access controls to ensure only authenticated entities access sensitive data. Traditional models often rely on perimeter security, assuming actors within the network are trustworthy. This assumption is often flawed, leading to breaches.
The core principles of Zero-Trust revolve around the philosophy of “never trust, always verify.” It mandates strict identity verification for everyone trying to access resources in a network, irrespective of their location. This approach works seamlessly with Cloud Security Principles, incorporating robust authentication methods and real-time monitoring to manage the integrity of access.
