A Methodology to Integrate Security and Cost-Effectiveness in ATM

Abstract

The objective of this paper is the definition of a new methodology for carrying out security risk assessment in the air traffic management (ATM) domain so as to enhance security awareness and integrate secure and cost-effective design objectives. This process is carried out by modelling the system, identifying the assets, threats and vulnerabilities, prioritizing the threats and proposing cost-effective countermeasures for the weaknesses found. ATM security is concerned with securing ATM assets in order to prevent threats and limit their effects on the overall aviation network. This effect limitation can be achieved by removing the vulnerability from the system and/or increasing the tolerance in case of component failures due to attacks. The security risk assessment methodology proposed is based on what is currently being done by the industry (the International Civil Aviation Organization (ICAO) and the International Standard Organization (ISO), etc.).

Modeling & Data Fusion to support Acquisition in Defense

“…The estimation is the result of weighted sum of all the particles; the weights associated to the particles represent the quality of the particles. [12], [19] Bayesian theory: it is a probability theory, and it defines the probability of an event that might happen under the condition of another event. In information fusion it provides a method for combining evidence according to the probability theory rules.…”

“…Zero means that there is completely lack of belief, while one means that the event will happen. [12], [19] Aggregation Operators: these operators refer to mathematical functions that are used for information fusion; they combine values and return a single value in the same domain. These types of operators are parametric, meaning that additional knowledge on the sources, like background knowledge, can be considered in the fusion process.…”
