Virtual servers are a weak link in data security management

Research conducted by Varonis has found that data security in virtualized environments is often neglected by IT organizations, with 48 percent either reporting or suspecting unauthorised access to files on virtualized servers. The study, conducted at VM World conferences, suggests that there is a limited awareness of security matters when it comes to virtualized servers, with 70 percent of respondents having little or no auditing in place on virtual servers.

Other findings included:

Application servers were virtualized by almost all respondents (87 percent), mainly due to speedier deployment (76 percent) and disaster recovery (74 percent). On the other hand, those who do not virtualize cite disk storage (37 percent), performance (30 percent) and a lack of advantages (20 percent) as they three main reasons for not doing so.

Across different company sizes, one area that appears to be neglected by organizations is file security. While almost 60 percent said they were very careful about setting permissions and controlling subsequent updates, a revealing 70 percent, regardless of company size, had implemented little or no auditing – even at the high end of the enterprise space. In fact, 20 percent of enterprises with more than 5,000 employees admitted to having no file logging capabilities in place.

The lack of sufficient security is further highlighted by 48 percent either reporting or suspecting unauthorised access to files on their virtualized servers – putting sensitive company information at risk of being misused, lost or stolen. Surprisingly, even for those who do audit all activity, a significant 68 percent believe there is still unauthorized access.
