Symantec is turning to virtualization and cloud computing to protect Web surfers and let them access Web-based applications from one site. The company demonstrated the technologies, along with another one designed to block malware from getting into corporate networks, to reporters and briefed them on its research and development strategy at an event it dubbed “Innovation Showcase” on Wednesday. Virtualization technology that essentially creates different machines on the same computer offers a good platform for securing PCs by providing different protected environments, said Joe Pasqua, vice president of research at Symantec Research Labs. Taking advantage of this trend, the company has developed Virtualization-based endpoint security, VIBES, technology that works with machines already running virtualization hardware and software to isolate three different areas on a computer for doing activities that require different levels of security.
