What You'll Learn

  • ✓Articulate why perimeter security fails for cloud and remote work
  • ✓Apply the NIST 800-207 zero-trust principles to architecture decisions
  • ✓Use identity (users, devices, workloads) as the primary control plane
  • ✓Design microsegmentation that limits blast radius
  • ✓Implement device-trust signals and conditional access
  • ✓Understand policy engines (PEP / PDP / PA) and decision flows
  • ✓Replace VPNs with Zero Trust Network Access (ZTNA)
  • ✓Plan a phased adoption against the CISA Zero Trust Maturity Model

Prerequisites

  • •Networking fundamentals (TCP/IP, DNS, TLS)
  • •Identity basics (SSO, OAuth, SAML, OIDC)
  • •Some exposure to cloud (AWS / Azure / GCP) or enterprise IAM
