چکیده

This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, confidentiality, integrity, maintainability, etc. Basic definitions are given first. They are then commented upon, and supplemented by additional definitions, which address the threats to dependability (faults, errors, failures), and the attributes of dependability. The discussion on the attributes encompasses the relationship of dependability with security, survivability and trustworthiness.

Security Ontology: Simulating Threats to Corporate Assets

Threat analysis and mitigation, both essential for corporate security, are time consuming, complex and demand expert knowledge. We present an approach for simulating threats to corporate assets, taking the entire infrastructure into account. Using this approach effective countermeasures and their costs can be calculated quickly without expert knowledge and a subsequent security decisions will b...

On the Resilience of the Dependability Framework to the Intrusion of New Security Threats

B. Randell has been instrumental, with others, in the definition of the dependability framework. Initially thought of with a strong emphasis on accidental faults, it has paid more attention over the years to intentional ones and, thus, to classical security concepts as well. Recently, a couple of incidents have received a lot of attention: the Hydraq and Stuxnet worms outbreaks. They have been ...

Behavior Based Estimation of Dependability for Autonomous Mobile Systems Using Particle Filter

The dependability of a system is particularly important when dealingwith autonomous or semiautonomous systems. With an increasing degree of autonomy and safety requirements, the requirements for dependability increase. Hence, being able to measure and compare the dependability of a system is more and more inevitable. Since autonomous mobile systems are usually described by their behavior it is ...

Taxonomy of Evolution and Dependability

Evolution is one of the major issues affecting system dependability as well as engineering activities and environments. The most common understanding considers evolution as a phenomenon that needs to be avoided. By contrast this paper takes into account evolution as a necessary feature of computerbased systems. This paper reviews a taxonomy of evolution identifying a conceptual framework to ana...
