How do security issues differ between physical and virtual environments?
Hezi Moore: Organizations leveraging virtualization technology are dealing with very dynamic environments that may be managed by multiple departments. Administrators are able to add more servers and do so faster and with fewer eyes on them and fewer controls in place. In contrast, physical servers are typically stationary; in the same place, the same rack, and with very little mobility. From a server perspective, there really are no changes in security from physical to virtual environments. However, the process has changed and it is necessary to manage the process and the virtual infrastructure a little differently as it relates to security. While virtualization provides significant cost and operational benefits for organizations, it introduces several new security challenges that traditional physical security devices cannot address. Unfortunately, many mission-critical servers are not leveraging the benefits of virtualization because of limited visibility and control inside the virtua
