Bottom line: Ruykhaver's take is that it's just a matter of time before a major vulnerability or threat in virtualized environments emerges. That includes going through a procurement process for VMs just as if they were physical machines," Steffen says. The decoupling of physical and logical states gives virtualization inherent security benefits. selects ", Follow everything from CIO.com on Twitter @CIOonline. But this has never happened "in the wild," so the threat remains theoretical for now. The CSA report notes that some organizations are complacent about virtualization security because there haven't been any known successful attacks on hypervisors except for theoretical ones that require access to the hypervisor source code. Virtualization: Issues, Security Threats, and Solutions 17:3 Fig. Not enough attention has been paid to patching and confirming the security of virtual servers.

Part 3: Best practices for controlling and managing virtual machines . Virtualization security is the collective measures, procedures and processes that ensure the protection of a virtualization infrastructure / environment. Also learn how the … Advertise | Some virtualization security companies have already utilized many of the solution concepts into their products to combat the vulnerabilities that are present. In a typical attack scenario, an attacker has to focus its attacks on one machine at a time, regardless of its intent: "Attack one machine to inflict harm on that one machine." the We think the following risks of the private cloud virtualization security … For some IT shops, virtualization gives a false sense of security. Unlike physical servers, which are the direct responsibility of the data-center or IT managers in whose physical domain they sit, responsibility for virtual servers is often left up in the air. Most recently those worries have included social-networking technologies such as Twitter and Facebook and other outlets through which employees could turn loose company confidential data. Administrators tend to dismiss virtualization security issues, largely due to the nature of the technology. 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. "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. VENOM, CVE-2015-3456, is a security vulnerability that impacts some common computer virtualization platforms, notably Xen, KVM, VirtualBox, and the native QEMU client. Using virtual machines complicates IT security in a big way for both companies running private cloud computing and service providers. Virtualization security is much more than just hardening the virtualization host. Virtualization, instead, gives a false sense of safety that does not exist. Silicon Valley startup Altor is finding some fans for its virtual firewalls, as is Reflex Systems, which migrated from physical to virtual firewalls to keep up with growth in that market, MacDonald says. And every one of them has to be patched and maintained the same way a non-virtual server does to keep up with potential vulnerabilities; a lot of people forget about that, but it makes the situation a lot more complicated. This section will examine the prominent approaches to virtualization security … Seven physical systems (top) and a virtualized equivalent implementation (bottom).

By: Brien Posey. geek Just fire off one of these virtual machines sitting in offline libraries. Virtualization can be used in many ways and requires appropriate security controls in each situation. "But unless you put virtualized security controls—virtual sniffers, virtual firewalls, all the same controls you'd use on a physical server, inside that network, you don't see what's going on. eclectic First, virtualization adds additional layers of infrastructure complexity. 1. However on moving over to virtual desktops and servers, there is a need to part rethink the security technological strategy to ensure the facets of security are aligned to good security practice. ", It's theoretically possible for hackers to attack the hypervisor layer specifically, or to take over a VM and use it to attack other VMs, according to according to Chris Steffen, principal technical architect at Kroll Factual Data, a credit-reporting and financial-information services agency in Loveland, Colo. One of the biggest challenges with virtualization is the lack of visibility into virtual networks used for communications between virtual machines. If these communications aren't monitored or controlled they are ripe for attack, notes Ruykhaver. Different models may support such a virtualization, including virtualization based on type-I and type-II hypervisors, OS-level virtualization, and unikernel virtualization. surprises However, the design, implementation, and deployment of virtualization technology have also opened up novel threats and security issues which, while not particular to system virtualization, take on new forms in relation to it. But what OS is in the package and is it patched, and if not, who is going to give you the patch? If anything, virtualization will be in place before anyone notices the security issues. This means monitoring for unusual events and anomalies also becomes more complex, which in turn makes it … Virtualization Security; Sign Up to Our E-Newsletter.

The overarching issue with virtual servers is responsibility, MacDonald says. These "intra-host threats" can elude any existing security protection schemes. Ruykhaver's conclusion is a bit of a stretch for me--I have never heard any technology executive wonder about virtualization security. Without some form of fail-safe, guest operating systems would have no way of knowing they are running on a compromised platform. "Each one of those virtual servers is still its' own separate server, though," MacDonald says. By Michael Simon Attorney at XPAN Law Group With the current pandemic, virtual meeting systems are now highly-popular, and seen as easy-to-use substitutes for in-person meetings. That's a tedious process for companies with libraries of hundreds of VM images, however, and does nothing to address the patch status of VMs that are running but might not have been patched or had new antivirus signatures installed for weeks or months.

Known Issues in ESET Virtualization Security ; How are virutal machines identified in ERA? This article will explore the ways you can use virtualization to increase the security of your Windows environment. Should it be the IT manager closest to the physical host?

Virtualization will become dominant in enterprises, but the security risks are fuzzy at best. Virtualization can be used in many ways and requires appropriate security controls in each situation. To data-center managers not specifically tasked with monitoring all the minute interactions of the VMs inside each host, a set of virtual servers becomes an invisible network within which there are few controls. 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. A centralized master sysadmin tasked with management and security for all the virtualized assets in an enterprise? Working from home doesn't have to be a series of compromises. ", "There are a lot of compliance and use issues," McDonald says. Virtual servers are designed to be, if not invisible, then at least very low profile, at least within the data center. Copyright © 2009 IDG Communications, Inc.

He is a well-known authority in the areas of system integration and security. It doesn't solve all the potential configuration problems, but it does concentrate all the security processes within a specific technology layer and development process. returns As for now, attacks on virtual systems are extremely rare, because virtualization platforms are not widely spread. The same threats from the physical world still apply in the virtual world. "But with VMs you have the potential for VMs to get completely out of hand and have so many out there you can't do anything about how secure they are.".
