Abstract: A method of noise reduction, including: collecting configuration data with agents from configuration items, transmitting the collected configuration data to a server for processing, blocking receipt of selected configuration data by a server load protection module to protect the server from overload, storing the configuration data at the server in a storage, processing the configuration data with a batch noise detection module that identifies noise in the configuration data; the batch noise detection module deduces rules based on the identified noise and stores the rules in a data knowledge repository, receiving a user query from a user using a front-end module, analyzing the configuration data with an analytical module to transform the configuration data to be aligned with the user query, responsive to the analysis applying a runtime noise detection module to identify and suppress transformed configuration data to remove irrelevant transformed configuration data.

Abstract: A method of evaluating change risk in an IT environment, including collecting environment state snapshots of configuration parameters in the IT environment, invoking a manifest of a change on the environment state snapshots to form simulated environment state snapshots, analyzing the simulated environment state snapshots relative to the environment state snapshots, deriving a risk score based on the analysis and selectively perform the change responsive to the risk score.

Abstract: A method of change reconciliation, including: detecting changes in configuration parameters collected from stations of a system and collecting or generating change request records for the detected changes, identifying unauthorized changes and authorized changes based on given rules, for a potentially authorized change that is not clearly authorized or unauthorized, identifying a context for the change request records, including: a) identifying authorized change implementers; b) identifying a scope of the content that is to be changed; c) identifying a time window when the change is allowed to be performed; identifying a context for the actual change, including: a) identifying a change implementer; b) identifying a scope of the content that was changed; c) identifying a time window when the change was performed; comparing the context of the change request with the context of the actual change; determining an authorization score responsive to said comparing; outputting the change authorization score.

Abstract: A method for analyzing and prioritizing changes to configuration parameters of applications in an information technology system, including collecting configuration parameters of applications executed on computer stations in a network, storing the collected configuration parameters in a database, comparing the configuration parameters of an application from a specific station with configuration parameters of the application at different stations, determining differences in the configuration parameters by the comparing, analyzing the determined differences according to a set of analysis dimensions that represent rules for evaluating the differences, assigning a score representing the level of conformity of the differences to each of the analysis dimensions, defining a context for reviewing the differences, assigning a weight to each analysis dimension representing the importance of the analysis dimension, adjusting the weights assigned to the analysis dimension based on the context, calculating a total risk for
