Describe concepts of security, compliance, and identityModerate

A company redesigns its access strategy so that no device or user is trusted by default, even when connected to the internal corporate network, and every access request is authenticated and authorized using all available signals. Which Zero Trust guiding principle does this describe?

Correct.

The concept

Zero Trust is built on three guiding principles: verify explicitly, use least privilege, and assume breach, which Conditional Access helps enforce.

Why this answer

Authenticating and authorizing every request based on all available data points, regardless of network location, is the definition of the verify explicitly principle.

  • Correct: this matches authenticating based on all available signals rather than trusting network location.
  • BLeast privilege is about limiting access rights and duration, not about validating every request with signals.
  • CAssume breach is about designing to limit damage after a compromise, not about validating requests up front.
  • DZero Trust explicitly moves away from relying on network perimeter defense as the security boundary.
  • ESingle sign-on is an authentication convenience feature, not one of the three Zero Trust guiding principles.
