Entity-wide database asset index generation

A computer system for entity-wide database asset index generation, the computer system comprising:

• a communication fabric;
• a storage device connected to the communication fabric, wherein the storage device stores program instructions;
• and
• a processor connected to the communication fabric, wherein the processor executes the program instructions to:
• generate an entity-wide database asset index corresponding to an entity identifying all observed database instances across a plurality of database servers by each respective security monitoring system of a plurality of different security monitoring systems corresponding to the entity and one or more linked sets of same database instances observed by more than one security monitoring system of the plurality of different security monitoring systems, wherein the one more linked sets of same database instances are matched based on similarities between database feature objects for each pair of database instances from the observed database instances, and wherein the matchings comprise:
• generate a similarity score for each pair of database instances of the observed database instances based on performing a comparison of the different sets of database feature objects corresponding to each pair of database instances;
• determine whether one or more pairs of database instances of the observed database instances have a corresponding similarity score greater than a similarity score threshold level;
• and
• perform security analytics on the entity-wide database asset index corresponding to the entity that identifies all of the observed database instances across the plurality of database servers by each respective security monitoring system of the plurality of different security monitoring systems corresponding to the entity and the one or more linked sets of same database instances observed by more than one security monitoring system of the plurality of different security monitoring systems to detect any database security threats.

A computer program product for entity-wide database asset index generation, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• generate an entity-wide database asset index corresponding to an entity identifying all observed database instances across a plurality of database servers by each respective security monitoring system of a plurality of different security monitoring systems corresponding to the entity and one or more linked sets of same database instances observed by more than one security monitoring system of the plurality of different security monitoring systems, wherein the one more linked sets of same database instances are matched based on similarities between database feature objects for each pair of database instances from the observed database instances, and wherein the matchings comprise:
• generate a similarity score for each pair of database instances of the observed database instances based on performing a comparison of the different sets of database feature objects corresponding to each pair of database instances;
• determine whether one or more pairs of database instances of the observed database instances have a corresponding similarity score greater than a similarity score threshold level;
• and
• perform security analytics on the entity-wide database asset index corresponding to the entity that identifies all of the observed database instances across the plurality of database servers by each respective security monitoring system of the plurality of different security monitoring systems corresponding to the entity and the one or more linked sets of same database instances observed by more than one security monitoring system of the plurality of different security monitoring systems to detect any database security threats.
