Abstract

A method and system for protecting access to remote systems, such as resource databases containing sensitive resources, such as cryptographic keys or personally identifying information, is disclosed. A server can receive a plurality of access requests from a requesting entity. The server can identify an entity profile corresponding to the access requests, as well as a machine learning model corresponding to the entity profile. The access requests can be used to form access sequences, which can be evaluated by the machine learning model. The machine learning model returns an anomaly score that can be compared to a threshold. If the anomaly score exceeds the threshold, the server can prevent further access to the remote system, for example, by revoking a credential associated with the requesting entity.
