Zero Trust principles
Also written: ZT
A security model that assumes no user or device is trusted by default and requires continuous verification for access to resources.
Zero Trust is a security strategy that operates on the idea that no one should be trusted automatically, even if they are already inside a network. Every attempt to access data or systems must be verified.
Think of it like a secure building. Instead of just showing your ID once at the front door, Zero Trust means you need to show your ID and get approval every time you want to enter a new room or access a specific file cabinet, even if you're already inside the building. This helps prevent unauthorized access if an attacker manages to get past the initial defenses.
Zero Trust is a cybersecurity framework that mandates strict identity verification for every person and device trying to access resources on a private network, regardless of their location. It operates on the principle of 'never trust, always verify,' moving away from traditional perimeter-based security models. Key components include micro-segmentation, least privilege access, and continuous monitoring and validation of user and device posture.
Microsoft's cybersecurity article highlights the need for strong security fundamentals, including Zero Trust, as AI advances. AI can be used to power cyberattacks, making robust verification and access controls essential.

Questions people ask
- Does Zero Trust mean I have to log in all the time?
- Not necessarily all the time, but it means systems are designed to re-verify your identity and permissions more frequently, especially when accessing sensitive data or performing critical actions.
- Is Zero Trust only for large companies?
- No, the principles of Zero Trust can be applied by individuals and smaller organizations to improve their security posture by being mindful of who and what is accessing their data.
