Research ArticleOpen accessIn the abstractA Stringent Authorization using Principles and Policy for Grid ComputingA. R. Jayasudha, T. PurusothamanProblem statement: The current information security mechanisms are insufficient to address authorization issues. The access control models today are mostly static and they are not wellsuited for the service-oriented environments where information access is dynamic in nature. Traditional authorization security techniques do not directly address these concerns as they primarily use access control lists for authorization, where the user whose … …Journal of Computer Science, Vol. 7, Issue 8 · 8 Aug 2011 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDFCite

It is noted that the current rental market conditions are to be examined thoroughly before any engagement in RM is to be instituted. The rental value per week for 1, 2-Bedroom Units and 3 … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 8 Jan 2018 · 7,487 accessesView PDFCite
Review ArticleOpen accessIn the abstractProject HARPRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The HARP project, abbreviated from the High Altitude Project, was considered a joint project of the United States Department of Defense and Canada's Department of Defense, originally designed to study low-cost re-entry vehicles. Generally, such projects used rocket launchers to launch missiles, costly and often inefficient. The HARP project used a non-rocket space launch method based on a very large … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 7 Nov 2017 · 19,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING FAULT TOLERANT RESOURCE OPTIMIZED AWARE JOB SCHEDULING FOR GRID COMPUTINGK. Nirmala Devi, A. TamilarasiWorkflow brokers of existing Grid Scheduling Systems are lack of cooperation mechanism which causes inefficient schedules of application distributed resources and it also worsens the utilization of various resources including network bandwidth and computational cycles. Furthermore considering the literature, all of these existing brokering systems primarily evolved around models of centralized hierarchical or client/server. In such models, vital responsibility such … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractPro-Active Prevention of Clone Node Attacks in Wireless Sensor NetworksK. M. Anandkumar, C. JayakumarProblem statement: Wireless mobile sensor networks are deploying large, self-organized and adaptable sets of sensors for many applications such as military, environmental, health care, remote monitoring and other applications. Unfortunately, the simplicity and low-cost of these sensors make eases cloning of compromised nodes by attackers in the network. Due to the unattended nature of wireless sensor networks, an adversary can … …Journal of Computer Science, Vol. 8, Issue 10 · 28 Aug 2012 · 7,072 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Trust System Based on Multi Level Virus DetectionYasmine H. Abdul-AmirProblem statement: As these detection methods were developed and implemented, the virus developers adapted to the new detectors in ways intended to defeat them. Approach: This study introduced new multilevel virus detection (MDS). Results: This system model depended on an advance behavior blocking technology. It detected virus-code by a behavior approach monitors and determined a virus activity at several protection … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,853 accessesView PDFCite
