Businesses today are confronted by increasingly mobile users and an increasing number of threats. They are expected to provide user-friendly access to resources while reliably protecting data at the same time. The ti&m policy server is a powerful yet easy-to-use authentication solution that substantially improves the security of your systems. Risk-based authentication captures the implicit characteristics of users and devices and analyzes user behavior in order to pinpoint deviations from regular behavior. These deviations can be used to determine how likely it is that a given login request is coming from the actual user or from a potential hacker. The higher the probability of an attack, the more comprehensive and restrictive the authentication process becomes.
