A method by one or more computing devices for detecting application user anomalies in audit logs of database operations performed on one or more databases. The method includes obtaining a first audit log of database operations, wherein the first audit log indicates (1) which application users of an application caused which of the database operations to be performed and (2) which functions of the application caused which of the database operations to be performed, generating, for each of the application users indicated in the first audit log, a profile of that application user that indicates which of the functions that application user is expected to touch, and detecting an anomaly in response to a determination that a second audit log indicates that an application user touched a function that is not one of the functions indicated in the profile of the application user.

Detecting behavioral anomalies in user-data access logs

A method by one or more runtime agents protecting a web application for capturing contextual information for data accesses. The method includes determining first metadata associated with a web application layer request sent by a web application firewall to the web application, determining second metadata associated with the web application layer request based on information available to the web application, serializing the first metadata and the second metadata to generate serialized metadata, and adding the serialized metadata to a database query that is to be submitted by the web application to the database server, wherein execution of the database query that includes the serialized metadata by the database server is to cause the database activity monitor to store the serialized metadata and third metadata associated with the database query determined by the database activity monitor in a data storage.

Capturing contextual information for data accesses to improve data security

A method for detecting anomalies in audit logs of database operations performed on databases. The method includes obtaining a first audit log of database operations performed on one or more databases, generating, for each of a plurality of attribute values associated with a designated attribute appearing in the first audit log, a profile of that attribute value that indicates expected attribute characteristics of one or more attributes when that attribute value is associated with the designated attribute, obtaining a second audit log of further database operations performed on the one or more databases, and detecting an anomaly responsive to a determination that a log entry in the second audit log includes an attribute value associated with the designated attribute but attributes in the log entry deviate from the expected attribute characteristics of the one or more attributes indicated by the profile of the attribute value associated with the designated attribute.
