Techniques for automatically discovering and protecting sensitive data are disclosed. In some embodiments, a set of data objects is searched for data matching a first set of one or more regular expressions and for metadata matching a second set of one or more regular expressions. A confidence score is then generated for a particular data objects in the set of data objects as a function of regular expressions in the first set of one or more regular expressions that match data stored in the particular data object and regular expression in the second set of one or more regular expressions that match metadata associated with the particular data object. One or more operations may be performed to protect sensitive data stored in the particular data object based, at least in part, on the confidence score.

Systems and methods for securing data based on discovered relationships

Techniques for automatically discovering relationships between data to enforce data security are disclosed. In some embodiments, a query analytic system receives a set of one or more queries that accesses data from a set of data objects and is generated by an application to accomplish an application-level function that is opaque to the query analytic system. The query analytic system detects a relationship between a first data object and a second data object based on access patterns associated with the set of one or more queries. The query analytic system further stores an indication that the first data object is related to the second data object. An operation that is performed against the first object may also be performed against the second object based on the stored indication. Additionally or alternatively, information about the second object may be displayed when information about related objects is requested for the first object.

Operations include halting a runaway query in response to determining that a performance metric of the query exceeds a performance threshold. The runaway query halting system receives a query execution plan associated with a query and divides the received execution plan into one or more components. For each component, the system determines a predicted resource usage associated with executing the component. The system further determines a predicted resource usage associated with the query execution plan based on the predicted resource usage associated with each component. The system executes the query associated with the received query execution plan and compares the predicted resource usage associated with the query to a resource usage threshold. In response to determining that the predicted resource usage of the query execution plan exceeds the resource usage threshold, the system halts execution of the query associated with the query execution plan.
