Zero Trust is not a product. It is a security philosophy based on one principle: never trust, always verify.
Why Traditional Security Models Fail
Older models assumed users inside the network were safe. With cloud services, remote work, and credential theft, that assumption no longer holds.
Core Principles of Zero Trust
- Verify every access request
- Enforce least privilege
- Assume breach
Practical Implementation Steps
- Enable multi-factor authentication
- Restrict administrative privileges
- Segment critical systems
- Monitor privileged account activity
Conclusion
Zero Trust reduces blast radius and limits the damage from compromised accounts. It is a strategy, not a single tool.
