Distributed component platforms isolate much of the conceptual and technical complexity involved in constructing component-based applications. The authors examine the concepts underlying DCPs, the two market leaders-Microsoft's DCOM and Sun's JavaBeans-and emerging Internet and OMG standards.

Cyber attacks continue to proliferate, with increasing sophistication and severity. Businesses and government agencies must establish robust governance, cultures, and data management processes to minimize vulnerability to such threats and ensure effective responses. Capability Maturity Models (CMMs) have been proposed to address this critical need; they enable organizations to benchmark their Cyber Security processes against a framework of recognized best practices. Unfortunately, CMMs are inherently static and diagnostic: they help identify maturity gaps, but are not directly actionable. This paper describes how to extend an existing Cyber Security CMM into a dynamic performance management framework through an intuitive Model-Simulate-Analyze methodology. This softwarebased framework enables organizations to formulate plans for improving their Cyber Security maturity levels; test and validate or refine those plans prior to roll-out; and monitor execution results to detect emerging problems and make appropriate midcourse adjustments to ensure success.
