Definition

NIST SP 800-207 describes Zero Trust as an evolving set of principles that move defenses from static network perimeters to users, assets, and resources.

The CISA pillars

  • Identity
  • Devices
  • Networks
  • Applications and workloads
  • Data

A practical starting point

  • Enforce MFA everywhere
  • Inventory devices and applications
  • Replace broad network access with per-application access

Questions to ask about any Zero Trust initiative

  • Which of the CISA pillars does this product cover, and which does it assume we already have?
  • How does it integrate with our identity provider and MFA?
  • What can we phase in first without disrupting how people work?
  • How do we measure progress rather than take 'Zero Trust' on trust?
