DATA SOURCE SECURITY CLUSTER

摘要

Methods, systems, and computer program for implementing data source security cluster are provided. Security tokens may be generated for a plurality of data sources. Clients may request a security token from each data source. The client may send the security tokens and a data query to a federation engine. The federation engine may generate a plurality of sub-queries from the query. The federation engine may match a sub-query and particular security token to a data source. The federation engine may validate each security token and send, to each data source, the matching sub-query for that data source. Each data source may send a result to a sub-query to the federation engine, which may join all of the results into a virtual view.

1. A data source security cluster system, comprising:
a federation engine structured with a memory and a processor, the processor in communication with the memory to:
generate a first data source security token and a second data source security token;send the first data source security token to a first data source and the second data source security token to a second data source;receive, from a client, a request comprising at least a query, a first security token and a second security token;extract the query, the first security token and the second security token from the request;query the first data source for the first data source security token and the second data source for the second data source security token;determine a first match between the first data source security token and the first security token;based upon the determining of the first match, authorizing the client to access the first data source;generate a first sub-query based on the query; andsend the first sub-query to the first data source.
