Risk-based authentication makes it possible to base authentication requirements and access decisions on the level of risk an access attempt poses. Simply put, the greater the risk, the higher the bar for access.
Today, you have more resources to protect, more users needing access to them from more places, and more threats of credentials-based attacks than ever. As a result, it’s tough to keep those resources secure while still making them easily accessible to people who legitimately need them. To achieve and maintain that balance, you need risk-based authentication (RBA).
