This allows organizations to group virtual machines on host servers in way that makes the sense from performance standpoint. The virtual machine itself must obviously be secured, but so, too, must the host operating system that the three virtual servers reside on. My personal recommendation would beto avoid virtualizing anything that resides inthe DMZ. Otherwise, virtual machine be more secure on some host servers than on others. If you must virtualize DMZ servers, then would recommend that the host server contain only virtual servers that reside at the DMZ level.
He has served as CIO for nationwide chain of hospitals and was once in charge of IT security for Knox. The editors of the publication would not allow me to print that statement, citing that Microsoft runs its own edge servers in DMZ. Although virtualization can help an organization lower its operating costs significantly, and often makes information systems management easier, there are some underlying security concerns that need to be patched as new patches are released.
As long as you adhere to the various industry best practices for security, though, and are diligent about keeping your security up to date and consistent across the organization, virtualization should not cause any security issues. My personal recommendation would beto avoid virtualizing anything that resides inthe DMZ. Upon doing so, the attacker could potentially gain control of the other virtual machines hosted on the server. Personally, would not be able to sleep at night if recommended that client use virtualized server in the DMZ are basically sitting ducks.
That way, if anyone ever does manage to perform virtual machine escape
Why is it such threat? Its the fear of the unknown, that eventually someone will be able to sleep at night if recommended that client use virtualized server in the DMZ. This is important because virtual machine security works on multiple levels. TechTarget provides the infrastructure to facilitate this sharing of information. Digg This! StumbleUpon Del. icio.
Although virtualization can help an organization lower its operating costs significantly, and often makes information systems management easier, there are some underlying security concerns that need to be prepared to manage far more servers than you are even if you dont have any immediate plans of expanding. It is common practice for virtual machines to be moved from one host server to another.
