1. Zuri Njoku Shares 7 Principles of Zero Trust Security Explained

2. Cyber threats are becoming smarter every day, and old security methods are no longer enough. Instead of trusting anything just because it’s inside the network, Zero Trust Security uses a safer method: trust nothing until it is checked. Here, Zuri Njoku explains the seven main principles of Zero Trust and how they help keep systems protected. Each principle works together to make sure trust is earned, not assumed.

3. Never Trust, Always Verify • Zero Trust starts with one basic idea: no one should be trusted automatically. Every time a person or device wants to access something, the system must check who it is and whether it is allowed. This helps stop unwanted access, even from inside the network.

4. Least Privilege Access This principle gives users and systems only the access they truly need. By limiting permissions, organizations can reduce the harm that could happen if a password is stolen or a system is misused. With only the necessary access, there is less risk of major damage. 1

5. Micro-Segmentation Instead of making the whole network open, Zero Trust divides it into smaller, separate sections. Each section has its own rules and checks. If a hacker gets into one part, they cannot easily move to other parts. This helps contain problems and protect important information.

6. ContinuousMonitoring and Validation In Zero Trust, security is always active. The system constantly watches user behavior, device activity, and events in real time. By doing this, it can quickly notice anything unusual or suspicious and take action before itgrows intoa bigger issue.

7. Multi-Factor Authentication • Strong identity checks are essential in Zero Trust, and multi-factor authentication is a key part of this. It requires users to prove who they are in more than one way such as a password plus a code, fingerprint, or mobile app approval. Even if a password is stolen, extra steps help keep accounts safe.

8. Device and Endpoint Verification Every device trying to connect must meet security standards. The system checks things like updates, security settings, and overall device health. If a device does not follow the rules, it cannot access the network. This prevents risky or outdated devices from causing problems. 1

9. Assume Breach This principle means always acting as if a security breach could already be happening. Instead of waiting to react, the system stays ready to detect and stop threats at any time. By assuming danger may be present, organizations stay alert and respond faster to keep their data safe.
