Zero Trust architecture: 2026

2026 Zero Trust = modern security architecture. NIST SP 800-207 standard. "Never trust, always verify". Critical Africa bank + government adoption.

TL;DR

- Zero Trust: never trust, always verify.

- NIST SP 800-207 standard.

- Replace perimeter-based security.

- Critical Africa bank + gov adoption.

Principles

`

• Verify explicitly (every request)
• Use least privilege access
• Assume breach (limit blast radius)

Implementation pillars:

• Identity (strong auth, MFA, FIDO2)
• Devices (compliance, EDR)
• Network (microsegmentation)
• Apps (workload identity, API security)
• Data (classification, encryption, DLP)
• Visibility + analytics (SIEM, UEBA)
• Automation (orchestration, response)
