Abstract
There are disclosed techniques for use in authentication. In one embodiment, the techniques comprise generating first and second distributions. The first distribution relating to risk scores expected to be produced by an authentication system in connection with requests to access a computerized resource. The expected risk scores are based on a normalization process configured to produce risk scores by normalizing raw risk scores in connection with requests. The second distribution relates to risk scores actually produced by the authentication system in connection with requests. The actual risk scores include risk scores normalized by the normalization process. The techniques also comprise comparing the first and second distributions by determining a Kolmogorov-Smirnov distance between the respective distributions. The techniques also comprise initiating, based on the comparison, a failover of the normalization process to a new normalization process for use by the authentication system.
