Researchers from North Carolina State University and IBM have invented a way to update computer systems packaged in virtual machines in a computer “cloud” — even when those programs are offline.
The new cloud computing patch tool developed by NC State and IBM is called Nuwa and protects virtual machines (VMs) from cyber-attacks by ensuring that they always receive important security upgrades. In addition, the researchers have determined that offline application of security patches is more than four times faster than online patch application. The tool is named after a Chinese goddess who patched a hole in the sky.
A paper describing the research, “Always Up-to-date — Scalable Offline Patching of VM Images in a Compute Cloud,” will be presented Dec. 10 at the Annual Computer Security Applications Conference in Austin, Texas. Continue reading …
