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.
