Securability for system of systems

Abstract: As the Department of Defense (DoD) pursues methods within the systems engineering process to combat potential information assurance (IA) vulnerabilities, a new paradigm is required. This paper introduces the concept of securability as a new ility to be considered within the systems life cycle. Alongside the traditional system ilities (i.e., reliability, maintainability, supportability, etc.), securability will establish a standardised, measurable and rigorous approach to ensuring a system meets its mission objectives in a secure manner. DoD systems security capability analysis continues to mature today with the improvement of information assurance controls (DoD 8500 and NIST 800-53), but it is still conducted in a non-standard ad hoc fashion in various phases of the systems life cycle. This paper provides a foundation for the concept of securability which will focus on the technical performance measures of a systems’ security from the beginning stages (e.g., concept development) to the end point (e.g., retirement and disposal). The time has come to establish securability as an integral part of the design and operational criteria for systems and the larger more vexing systems of systems through a formal and rigorous engineering approach instead of the current external and ad hoc approach.

Formal Modelling of Goals in Organizations

Abstract: Each organization exists or is created for the achievement of one or more goals. To ensure continued success, the organization should monitor its performance with respect to the formulated goals. In practice the performance of an organization is often evaluated by estimating its performance indicators. In most existing approaches on organization modelling the relation between performance indicators and goals remains implicit. This paper proposes a formal framework for modelling goals based on performance indicators and defines mechanisms for establishing goal satisfaction, which enable evaluation of organizational performance. Methodological and analysis issues related to goals are discussed in the paper. The described framework is a part of a general framework for organization modelling and analysis.

An American Aid Mission Director's View of Technical Co-operation:

Abstract: Economic development is now a prime national imperative in the less-advanced countries of the world. Tech nical co-operation—the organized international transfer of technical knowledge and skills—is one of the ways in which the more developed countries can aid less advanced ones to achieve their aspirations. The principal requirements for eco nomic growth are a development climate, capital, and modern technology. The creation of an environment conducive to progress is a task for indigenous political leadership. Once that leadership faces up to its responsibilities, technical co operation can contribute substantially to the country's eco nomic growth—especially in assistance in economic planning; in introducing new techniques in agriculture, industry, and the public services; in the development of extension methods for spreading technical knowledge; and in the training of profes sional and technical manpower. A key characteristic of the United States' technical co-operation program is its emphasis upon mut...

Development and Extension of a Deterministic System of Systems Performance Prediction Methodology for an Acknowledged System of Systems

Abstract: : This paper addresses the need for predicting performance in a system of systems (SoS) during incremental development and for dealing with the inherent variability associated with predicting performance. Historically, senior decision-makers have used technical performance measures (TPM), along with modeling and simulation, to predict whether a system under development will meet performance requirements. This methodology does not appear to be directly translatable to SoS for several reasons, including the inherent complexity of the SoS and the operational flexibility the end user may have in employing the SoS. An approach for dealing with the SoS performance prediction has been presented previously. It laid out a notional approach to dealing with this issue. This approach has been generalized to address the use and integration of multiple technologies into an SoS and into the decision-maker's options in the use of these technologies that is rooted in using subject matter expert input and historical data. This methodology is used to develop a metric defined as an SoS performance measure (SPM), which serves as an equivalent in functionality to a TPM for a SoS. Similar to TPMs, an approach to developing tolerance bands is presented to be used for predicting the status of development as a function of time. The methodology is first presented as a deterministic method for predicting SoS performance during development. This method is then demonstrated using an example case to illustrate the methodology. However, many of the component variables have significant uncertainty associated with them during SoS development and integration into the SoS. The paper provides an approach for expanding the SPM concept to account for this uncertainty using a stochastic approach to address this issue.
