Researchers from North Carolina State University have developed a new software tool to prevent performance disruptions in cloud computing systems by automatically identifying and responding to potential anomalies before they can develop into problems. Cloud computing enables users to create multiple “virtual machines” that operate independently, even though they are all operating on one large computing platform. However, this approach can cause performance issues when a software bug, or other problem, in one virtual machine […]

How does security apply to Cloud Computing? In this article, we address this question by listing the five top security challenges for Cloud Computing, and examine some of the solutions to ensure secure Cloud Computing. Organizations and enterprises are increasingly considering Cloud Computing to save money and to increase efficiency. However, while the benefits of Cloud Computing are clear, most organizations continue to be concerned about the associated security implications. Due to the shared nature […]
Botnets and their masters can communicate with each other by calling into the same VoIP conference call and swapping data using touch tones, researchers demonstrated at Defcon. This gives the botmasters, whose top goals include remaining anonymous, the ability to issue orders from random payphones and disposable wireless handsets, said researchers Itzik Kotler and Iftach Ian Amit of security and risk assessment firm Security Art. Using phones and the public phone networks eliminates one of […]
The rush toward virtualisation of internal enterprise computing resources and cloud computing can have many advantages, such as server consolidation, but it’s largely outracing traditional security and identity management practices. That’s leaving huge gaps, a sense of chaos and questions about where security products and services should be applied in the world of multi-vendor virtual-machine (VM) hypervisors. “Virtualisation will radically change how you secure and manage your computing environment,” Gartner analyst Neil MacDonald said this […]
As companies glom onto cloud computing, stateless computing is likely to emerge as a core tenant within the cloud and one that can deliver cost savings, predicted the chief technology architect for Merrill Lynch. LinuxWorld But to get to the state of stateless computing, companies will need to change the way they view their hardware needs and how they store and access the information, said Jeffrey Birnbaum of Merrill Lynch, who served as a keynote […]
