Security risk mitigation is a salient issue in systems development research. This paper introduces a lightweight approach to security risk mitigation that can be used within an Agile Development framework -the Security Obstacle Mitigation Model (SOMM). The SOMM uses the concept of trust assumptions to derive obstacles and the concept of misuse cases to model the obstacles. A synthetic scenario, based on an on-line system, shows how the SOMM is used to anticipate malicious behaviour with respect to an operational information system and to document a priori how this malicious behaviour should be mitigated. Since the SOMM is conceptually simple in deployment, its use is well within the capacities of the users who form part of an Agile Development team and crucially it should not take up a significant amount of development time.
The paper presents methodologies for efficient simulation and design of electromagnetic effects in microelectronic circuits for digital, analog, mixed-signal, RF and microwave applications in time and frequency domain. Also parallelization of the presented methodologies and incorporation into standard design flow has been discussed.
A generic object-oriented enterprise modeling process (GOOEMP) is a set of partially ordered steps intended to reach the objective of building a fully integrated, dynamic, object-oriented model of the enterprise. An abstraction mechanism is proposed to enable this process. The process is generic because it applies to most types of enterprises. Enterprise models are the products developed from the process and these can be used by various stakeholders in an organization to: a) give them an understanding of the enterprise; b) design integrated information systems; c) respond to business changes by evolving their enterprise models and information systems in a coordinated and coherent manner; and d) enable the enterprise models built within a particular industry to be reused and applied to many other industries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
