The most probable answer for this is “Yes”. It varies with ease depending on the nature of storage and hypervisor that is mostly used by the VPS provider. Most of the time it is observed that a virtual machine’s virtual hard drive is carved out of shared SAN storage using file-system in clustered way such as VMFS, either ISCSI or fiber channel. The VPS server management services provide access to coding and db of the client’s server.
Managed VPS
- SAN snapshot as well as VM Snapshot can be used with file-system so as to acquire an image of the VM’s hard drive that is provisioned to a virtual machine.
- From a technology perspective, it is “yes”, as they have access to the hypervisor where your linux virtual server resides because that’s necessary to perform maintenance on occasion but a lot of the security concerns about having random company administrators having access to your “server” or “image” that can be lifted if there is a clear separation of the control panel and admin privileges from the actual hypervisor layer itself.
- In today’s world of physical server hosting, you have an additional monitoring capabilities like chassis intrusion detection sensors implemented via IPMI and monitored by the baseboard management controller, unfortunately those niceties don’t exist in virtualized infrastructures.
- Application level encryption and disk encryption can be sorted by countermeasures, although key management then becomes the issue in this scenario. It is all but impossible to secure the virtual machine’s physical memory pages.
