Resource failures risk assessment modelling in distributed environments

Raid Alsoghayer, Karim Djemame
2014 Journal of Systems and Software  
We propose a mathematical model to predict the risk of failure of resources in such environments using a discrete-time analytical model driven by reliability functions fitted to observed data.  ...  Service providers offer access to resources and services in distributed environments such as Grids and Clouds through formal Service level Agreements (SLA), and need well-balanced infrastructures so that  ...  This research can be extended in many ways: 1) consideration of dynamic data, such as the current resource load or the availability of administrators to enhance the model; 2) risk assessment at the level  ...

Maximizing an Organization's Information Security Posture by Distributedly Assessing and Remedying System Vulnerabilities

Yonesy F. Nunez
2008 2008 IEEE International Conference on Networking, Sensing and Control  
The framework proposed in this paper is timely since most peer-to-peer distribution models focus more on content delivery and resource allocation.  ...  Malicious mobile code, specifically worms, are very efficient in their distribution, this is because they are able to infect other systems in a peer-to-peer distributed fashion.  ...  This distributed environment is primordial for the assessment of vulnerabilities and the distribution A6.4 of patches to minimize the risk exposure of vulnerable systems and, ultimately, increase an organization's  ...
