Abstract
Computer security protection of virtual machines is remotely managed by a security manager that communicates with a security agent in each of the virtual machines. The security manager sends a sequence marker to a virtual machine, and expects to receive the sequence marker back from the virtual machine. When the security manager detects that a virtual machine sends a sequence marker that is the same as a previously received sequence marker, the security manager detects that the virtual machine is a clone or a rollback of another virtual machine. In response, the security manager provisions computer security in the virtual machine.
