Zero trust is a posture, not a product. Module 16 (Cloud track) covered ZTNA specifically. This module is the architectural view.
The seven pillars (NIST)
- User/identity
- Device
- Network/environment
- Application/workload
- Data
- Visibility/analytics
- Automation/orchestration
Core principles
- Never trust; always verify
- Assume breach
- Least privilege
- Continuous verification
Phased rollout (24-36 months realistic)
- Identity — strong IdP, MFA, conditional access
- Device — managed devices required for sensitive access
- Network — ZTNA replaces VPN
- Workload — service mesh + mTLS
- Data — classification + encryption
- Analytics — UEBA + continuous monitoring
Common misconceptions
- “We bought a ZTNA product = Zero Trust” — no
- “Zero Trust replaces firewalls” — they’re complementary
- “Zero Trust is a 6-month project” — multi-year
