1Introduction
Traditional security relied on a perimeter: anyone inside the network was trusted. With remote work, cloud services and sophisticated attacks, that assumption fails. NIST published SP 800-207 on Zero Trust Architecture in August 2020.
2Discussion
Its tenets: all data sources and services are resources; all communication is secured regardless of location; access is granted per session with least privilege; access decisions use dynamic policy and the state of user, device and behaviour; and the security posture of all assets is continuously monitored.
3Conclusion
Zero trust is not a product but a journey that starts with asset inventory, strong multi-factor authentication and segmented access. For financial systems, least privilege is the backbone of data protection.
