New Tools to Identify and Protect Against Cloud Computing Problems
Thanks to practically omnipresence wireless networks and high speed Internet connections, cloud computing has become quite a buzz word and is being used in a myriad of ways. Antivirus software, office software, and even some image and video editing tools are using cloud computing in one capacity or another by more and more people. This increased use is making it more and more important that the hardware supporting the cloud is functioning correctly, and researchers at North Carolina State University have created a piece of software to help with that.
This new tool is a very light program, taking less than 1% of a CPU's maximum load and using only 16 MB of memory, that monitors system level information for any deviations from the norm. If a virtual machine sees a sudden change in CPU, memory, network traffic, or other factors, the software will examine the situation to determine what factor is behaving unusually. This then leads to it call in the correct utility, such as an antimalware tool, to address the problem.
All of this is accomplished without compromising any user data, as the software only considers system-level data, and when benchmarked identified as much as 98% of all anomalies. This is higher than traditional approaches to this task, while still only having a 1.7% false positive rate, which is quite low. In fact, that is so low that as the responses are automatic and easily reversible, the researchers point out the cost for them is negligible.
