Abstract: A computer system, method, and computer readable product are provided for identifying and isolating library code that has been obfuscated in software applications. A call graph is created for the execution of at least one module of preexisting library code within a bundle of software modules through either static analysis of the software code or dynamic analysis of the executing code, and then one or more anchor points are devised based upon the call graph that are indicative of the preexisting library code. Then a bundle of software modules can be analyzed or its execution monitored to determine if a discrete module of library code is present in the executing bundle based upon the modules' interaction with the one or more anchor points, and the discrete module of library code in the executing bundle can be identified as a module of preexisting library code.

A method includes monitoring a run-time state of each of multiple components of a distributed application to determine one or more sequence of events that triggers a fault injection point at one of the multiple components; defining a fault injection scenario in a specification based on said monitoring, wherein said fault injection scenario comprises a description of one or more sequence of events during which an intended fault is to be injected to a target component of the multiple components at one selected event; and executing the fault injection defined in the specification to perform injection of the intended fault during run-time of the distributed application.

Abstract: An approach for ontological policy based data collection, processing, and negotiation for data in view of analytics is provided. The approach searches one or more data sources for data related to a data request. The approach collects data related to the data request from the one or more data sources. The approach determines whether one or more attributes generated from the data request match one or more descriptors associated with the data related to the data request. The approach creates one or more annotated ontologies for the data related to the data request. The approach displays a hierarchical visualization of the one or more annotated ontologies for the data related to the data request. The approach updates the one or more annotated ontologies for the data related to the data request based, at least in part, on an evaluation of the quality of the one or more data selections.
