A proper asset modeling is essential to develop an information security risk assessment in any corporation. A too complex model will take a long development time and may require parameter values difficult to get. On the contrary, a too simple model will provide inaccurate estimations of risks, although it could be developed fast. One of the characteristic that most influences the complexity of the model is the way to characterize the dependence between assets, generally using a dependency graph. This work evaluates how slight variations in the complexity of the dependency graph affect to estimated risks. To carry out the evaluation, the MAGERIT methodology is used because it can handle graphs of variable complexity and allows qualitative or quantitative asset valuation. Finally, this work provides insights to select a proper complexity for the asset modeling approach used. Read More Read Less

This research means to present a novel collision avoidance strategy for autonomous road vehicles utilizing a metaheuristic approach named ‘Particle Swarm Optimization’. In exceedingly dynamic street environment, changes happen most of the time and in order to adapt to these changes vulnerability an exceptionally vigorous and capable calculation is required. Thus, PSO based plan won for being computationally sparing. The proposed PSO based impact evasion plan has been executed utilizing a swarm of 30 particles. PSO gives back an improved choice which can get away from the mischance situation with the exactness of more prominent than 93%. The presented exactness is in correlation with a perfect arrangement which has been acquired from earlier learning of the predetermined area. The strength and productivity of exhibited plan are stamped after its correlation with another collision avoidance technique based on ‘Genetic Algorithm’ which is also a biologically inspired optimization algorithm. The two plans were looked at on the premise of the quality of solutions being produced and required computation time. Re-enactment results have demonstrated the value of PSO construct approach in the light of two presented measurements. Read More Read Less

Abstract The Internet of Things (IoT) is an emerging paradigm in which physical objects are connected to each other and user via the Internet in order to share information between devices and systems.

The Internet of Things (IoT) is an emerging paradigm in which physical objects are connected to each other and user via the Internet in order to share information between devices and systems. In the IoT environment, smart devices are deployed to monitor, control and analyze business, personal, and social activities. The pervasive nature of the IoT may well be beneficial but it also presents a risk from malware, hacker intrusion, viruses and the like. The consequent security and privacy issues may cause physical damage and even threaten human lives. This paper targets two areas; initially,the paper provides a review of the IoT layered architecture with the security challenges/attacks to setting up an IoT environment. After that, the paper proposes a solution which can preserve the privacy of multimedia data within anIoT environment atits perception layer. The proposed security solutionwill support the multimedia to function effectively, while at the same time preserving the confidentiality of the information transmitted and the privacy of individuals.
