The Future of Zero Trust Architectures
Zero Trust is not a product, but a set of architectural principles based on the fundamental premise that there is no implicit trust granted to any entity.
Introduction
As organizations move further into hybrid and multi-cloud environments, the traditional perimeter-based security model has proven insufficient. This paper explores the core tenets of modern Zero Trust architectures.
Key Principles
- Verify Explicitly: Always authenticate and authorize based on all available data points, including user identity, location, device health, service or workload, data classification, and anomalies.
- Use Least Privilege Access: Limit user access with just-in-time and just-enough-access (JIT/JEA), risk-based adaptive policies, and data protection to secure both data and productivity.
- Assume Breach: Minimize blast radius for breaches and prevent lateral movement by segmenting access by network, user, devices, and application awareness.
