Conditional Access
An access-control approach that grants, challenges, or blocks authentication based on conditions like user risk, device health, location, and the sensitivity of what is being accessed, so access decisions adapt to context rather than being all-or-nothing.
Conditional access evaluates signals at sign-in, who, from where, on what device, how risky, and applies a policy: allow, require MFA, require a compliant device, or block. This makes authentication risk-aware, tightening controls when context is suspicious while staying frictionless when it is normal. It is a foundational modern IAM control and a practical expression of zero-trust principles applied to identity.
Introduced in: Identity and Access Management, IAM Engineer Fundamentals
Examples
- Requiring MFA only when a sign-in comes from an unfamiliar location.
- Blocking access from a non-compliant or unmanaged device.
- Allowing low-risk logins seamlessly while challenging high-risk ones.
