Abstract:
1. A method for acquiring statistical access models, comprising: collecting data associated with a first access profile for a first group of users that includes a designated user, wherein the first group of users is distinct from a second group of users; collecting data associated with a second access profile for the second group of users; comparing the data associated with the first access profile to the data associated with the second access profile, wherein the data includes a job title associated with the first access profile and a job title associated with the second access profile respectively; determining whether the data associated with the first access profile has a particular number of characteristics in common with the data associated with the second access profile; determining a first statistical access model based on the first access profile and a second statistical access model based on the second access profile; merging the first statistical access model and the second statistical access model into a merged statistical access model in response to a determination that the data associated with the first access profile has the particular number of characteristics in common with the data associated with the second access profile; assigning the merged statistical access model to the first access profile for the designated user; and detecting an anomalous access event of the designated user based on the merged statistical access model.
