Passive classification of data in a database based on an event log database

A set of one or more non-transitory computer readable storage media storing instructions which, when executed by one or more processors of one or more computing devices, cause the one or more computing devices to perform operations for passively classifying data in a database based on event logs stored in an event log database, the operations comprising:

• retrieving a first event log from the event log database, wherein the first event log represents a transaction involving a client device and the database;
• extracting one or more pieces of information from the first event log to generate classification data;
• generating a set of sensitivity scores corresponding to the one or more pieces of information, wherein each sensitivity score indicates the level of sensitivity associated with a corresponding piece of information from the one or more pieces of information;
• and
• storing the set of sensitivity scores in a score database.

A computing device configured to passively classify data in a database based on event logs stored in an event log database, the computing device comprising:

• one or more processors;
• and
• a non-transitory machine-readable storage medium having instructions stored therein, which when executed by the one or more processors, causes the computing device to:
• retrieve a first event log from the event log database, wherein the first event log represents a transaction involving a client device and the database;
• extract one or more pieces of information from the first event log to generate classification data;
• generate a set of sensitivity scores corresponding to the one or more pieces of information, wherein each sensitivity score indicates the level of sensitivity associated with a corresponding piece of information from the one or more pieces of information;
• and
• store the set of sensitivity scores in a score database.
