An attack in which many computers (distributed globally) and many internet connections are used to overload the target server by sending hundreds and thousands of requests, forcing it to shut down.

DDoS mitigation is a technique for resisting distributed denial of service (DDoS) attacks on networks attached to the Internet by passing network traffic addressed to the attacked network through high-capacity networks with "traffic scrubbing" filters.

A data mining strategy in which anonymous data is cross-referenced with other data sources to re-identify the anonymous data source. Any information that distinguishes one data source from another can be used for de-anonymization.

DebugDiag is a post mortem debugging tool which captures memory dumps for different types of issues (Hang/Crash/Memory), run basic analysis on the captured dumps and generates a report to understand the results and exposes an object model which can be used to easily access the information available inside the memory dump file (memory dump file extensions are usually DMP / PDMP / MDMP)

The process of locating and fixing or bypassing bugs (errors) in computer program code or the engineering of a hardware device. To debug a program or hardware device is to start with a problem, isolate the source of the problem, and then fix it. 

A type of application used in data mining to simplify complex strategic challenges and evaluate the cost-effectiveness of research and business decisions. The intent is to ensure that data is accurately described, categorized and analyzed.

A  framework for complex work that allows components to remain completely autonomous and unaware of each other. E.g. in Cloud computing, the cloud provider manages the physical infrastructure, but not the applications or data hosted on it.
