If the hacker owns the hypervisor, he/she owns all data traversing the hypervisor and is in a position to sample, redirect, or spoof anything. If a hypervisor needed to be patched all virtual machines would have to be brought down. VMSafe, the APIs that VMware built into the VSphere version of its virtual infrastructure product, makes it possible for third-party security vendors to apply their applications to VMware VMs. "There's an operating system and application in every package, every one with its own configuration and patch status and you have no idea what's in there or who's going to maintain it or what the long-term risk is going to be," MacDonald says. No matter their age, interests, or ability, these gifts will put a smile on any hacker's face this holiday season. On the other hand, they require far more resources than directly depending on hardware virtualization for security, so let us describe that next. Virtual machines have to communicate and share data with each other. Most companies don't need quite that layer of protection, which was designed for Special Forces groups serving overseas. But this has never happened "in the wild," so the threat remains theoretical for now. And that's the base of the problem.

This "hyperjacking" scenario is particularly frightening if we consider large-scale virtualization platforms that offer 10, 50, even hundreds of hosted servers running on a single piece of hardware. Hypervisors introduce a new layer of privileged software that can be attacked. But they do have a range of pressing security concerns—many of which they either don't recognize, or don't appreciate fully, MacDonald says. The National Security Agency has taken that concern not only to heart, but to software development labs, coming up with a virtual-server management scheme called NetTop that requires a configuration preventing VMs running on the same machine from interfering with one another. geek Here's a look at the five top virtual server security concerns of the moment. While they provide an easy-to-implement platform for scalable, high-availability services, they also introduce new security issues. Also learn how the … In many ways virtual machines are more secure than standalone servers, if only because they are more isolated and because they depend on a single host server, which makes the physical security issue much simpler than if each were on a separate piece of hardware, he says. | January 22, 2008 -- 03:35 GMT (03:35 GMT) and ", Follow everything from CIO.com on Twitter @CIOonline. 1.

Another consequence of the lack of oversight of virtual machines is sprawl—the uncontrolled proliferation of virtual machines launched, and often forgotten, by IT managers, developers or business-unit managers who want extra servers for some specific purpose, and lose track of them later. There's something about saving so much on hardware, easy server provisioning and more IT flexibility that overshadows any security worries. Virtualization defined. Using virtual machines complicates IT security in a big way for both companies running private cloud computing and service providers. This story, "Server Virtualization: Top Five Security Concerns" was originally published by CIO Join the Network World communities on Facebook and LinkedIn to comment on topics that are top of mind. "Just because you don't have a sniffer to see those packets moving between the virtual servers doesn't mean they're not there," MacDonald says. As discussed previously, complexity is the enemy of security 1; the sheer complexity of virtualization software may cause security problems. We think the following risks of the private cloud virtualization security … You can view virtual machines in ERA directly from Dashboard or from the Computers tab in the main menu, using the filter "Agentless virtual machine." With the growth of virtualization and problems in virtualization security, many firms and researchers have developed ways to combat the potential vulnerabilities. 3 key issues for secure virtualization Deal with these three main security concerns to improve your virtualized IT environment, says Bernard Golden Simon Crosby, chief technology officer of Citrix Systems, said during a security debate at the RSA conference that security should be built into the applications, not the hypervisor or virtual-infrastructure management products. curiosities, For some IT shops, virtualization gives a false sense of security. This means monitoring for unusual events and anomalies also becomes more complex, which in turn makes it … "P… Because of its VBS disabled requirement it becomes useless for anyone using Hyper-v, Docker, WSL, Virtual Machine Platform, etc. If attackers gain access to your host-level or VMware vCenter server, this opens doors for them to access other important VMs, or even create a user account with admin rights that could be used over a long period of time to collect or destroy sensitive company data. So we don't know a true security level of virtualization platforms. "Each one of those virtual servers is still its' own separate server, though," MacDonald says. In 2007, the NSA and contractor General Dynamics expanded that security with a workstation running what it calls the High-Assurance Platform—a virtualized operating system that includes a separate layer of code that is responsible for securing both the virtual operating system and application and the data they use. One of the very best things about virtual infrastructures is the ability to buy or test a product from a third-party vendor and have it up and running in minutes, rather than having to clear space on a test server, install the software, get it to talk to the operating system and the network and then, hours later, see whether it does what it's supposed to, MacDonald says. Running these security applications inside VBS provides offers greatly increased protection from vulnerabilities in the operating system, and prevents the use of malicious OS exploits which attempt to defeat protections. When a VM is infected with malware, early detection usually means the threat is restricted to that VM. Hypervisors help in secure isolation of multiple virtual machines running on single physical hardware. Thus, operating systems offer a level of abstraction above the hardware, on which multiple processes can run concurrently. A centralized master sysadmin tasked with management and security for all the virtualized assets in an enterprise?
