NetworkAppliance Server Virtualization Accreditation
VMware at the moment dominates the area of virtualization, however that does not imply that there don't seem to be different virtualization companies.
Cisco this week announced a brand new partnership with Microsoft to convey the Nexus 1000V digital switch and the digital laptop textile Extender (VM-FEX) for Hyper-V environments. the trouble isn't for presently transport version of windows Server, but quite is for the upcoming windows Server 8, which continues to be in development.
The Nexus 1000v was first introduced again in 2008 for VMware. The 1000v is a virtual switch for virtual computing device traffic.
"really here's a testament to the integration that we're bringing together into the Hyper-V environment for home windows Server 8 subsequent 12 months," Prashant Gandhi, senior director product advertising and marketing stated.
As to why Cisco has chosen to wait for Server 8 instead of making a edition of its virtual switch accessible for present types of Hyper-V, it has to do with new capabilities coming from Microsoft. Gandhi referred to that Server eight will encompass a brand new Hyper-V extensibility framework that benefits switching.
"The extensibility is richer and greater bendy than it has been in the past," Gandhi referred to. "So we determined to leverage that versus offering a solution in the latest environment."
The Nexus 1000v implementation for Hyper-V will be able to deal with site visitors that comes in from outdoor to the server ambiance. As well, it will probably handle site visitors within a server across distinct virtual machines.
"So it might give control and visibility throughout what we call North/South traffic, actual to virtual, after which East/West, virtual to digital," Gandhi pointed out.
Gandhi stated that Cisco doesn't at the moment have a bundling software in vicinity with Microsoft for the Nexus 1000v, although it does have one with VMware. Cisco is presently working bringing the Hyper-V focused items into a private beta now, while the total solution isn't set to be often accessible unless 2012.
Cisco supports assorted virtualization environments including VMware and KVM with its networking applied sciences. When it comes to enabling solutions throughout the different hypervisors, Gandhi pointed out that Cisco is aiming for a constant usability experience.
From a management viewpoint, Gandhi stated that customers typically have their hypervisor management programs provided by using the hypervisor supplier. The Cisco approach is to be in a position to combine into the hypervisor vendor device whereas at the identical time enabling the community crew to write guidelines.
"nowadays we provide the 1000v built-in into VMware environments and we can be doing a similar integration with the Microsoft digital administration equipment," Gandhi said.

NIST's how-to on securing digital machines
instructions aim to address the layers of complexity that include virtualization
by means of William Jackson
Feb 02, 2011
Virtualization, which can enable distinct operating techniques to run on a single platform and emulate separate machines, offers the promise of efficiency and might assist to permit cloud computing, however can come on the charge of expanded complexity and possibility, the national Institute of specifications and safety warns.
NIST has launched a group of guidelines for addressing these risks in special ebook 800-a hundred twenty five, "guide to protection for Full Virtualization technologies.”
The instructions complement recently launched drafts of NIST security instructions for public cloud computing. The agency additionally has set up a brand new wiki, the Cloud Computing Collaboration website to permit communique among the cloud neighborhood and NIST cloud research working groups.
“The fresh raise within the use of full virtualization products and services has been pushed by many merits,” the instructions say. Mounting distinct virtual machines on a single server could make greater effective use of hardware and processing potential, and may give desktops with entry to loads of operating techniques and applications. “laptop virtualization also helps more suitable manage of OSes to be sure that they meet the organization’s safety requirements.”
NIST e book tackles safety challenges of public cloud computing
but, “full virtualization has some negative security implications,” NIST warns. “Virtualization adds layers of know-how, that could raise the safety administration burden by way of necessitating additional security controls. additionally, combining many systems onto a single actual desktop may cause a larger impact if a security compromise happens.”
Ease of sharing information between programs can also open new attack vectors if no longer cautiously controlled. “In some instances, virtualized environments are reasonably dynamic, which makes creating and retaining the essential safety boundaries extra advanced.”
SP 800-a hundred twenty five addresses safety considerations for both server and laptop virtualization, building on generic safety most beneficial practices to supply selected tips for the brand new environments. Its suggestions are to:
comfortable all facets of a full virtualization solution and keep their protection. The security of a full virtualization answer is closely stylish on the particular person security of each and every of its add-ons, from the hypervisor and host working system to visitor working systems, functions and storage.
hinder and offer protection to administrator access to the virtualization answer. The protection of the whole digital infrastructure relies on the protection of the virtualization management gadget that controls the hypervisor and permits the operator to birth visitor operating techniques, create new visitor working equipment pictures and function different administrative movements.
make certain that the hypervisor is properly secured. Securing a hypervisor contains moves which are usual for any classification of utility, equivalent to setting up updates. different advised movements particular to hypervisors include disabling unused digital hardware, disabling unneeded hypervisor features, and monitoring the safety of each visitor operating gadget operating inside it in addition to undertaking happening between visitor operating programs.
carefully plan the safety for a full virtualization solution before installation, configuring and deploying it. protection may still be considered from the preliminary starting stage of the methods building life cycle to maximise safety and lower prices. it's much greater elaborate and expensive to handle safety after deployment and implementation.
NIST also has proposed instructions for addressing the challenges of cloud computing in draft SP 800-one hundred forty four, "instructions on protection and privateness in Public Cloud Computing," together with a concise definition of cloud computing in draft SP 800-one hundred forty five.
“The safety challenges cloud computing items are bold, primarily for public clouds whose infrastructure and computational components are owned through an outside birthday party that sells those capabilities to the regularly occurring public,” the guidelines say. They give a top level view of safety and privacy challenges, and elements out considerations that groups should still take when outsourcing facts, functions and infrastructure to a public cloud.
To foster collaboration among the cloud neighborhood and assist make certain the executive's at ease adoption of cloud computing, NIST additionally has deploy the Cloud Computing Collaboration.
This website includes well-known assistance about NIST's cloud computing software and activities. These pages are used by using the NIST-backed working groups dependent at the November Cloud Computing forum and Workshop II. The pages provide descriptions of the neighborhood's task, weekly meeting counsel and working documents. Registration is required to make a contribution to the wiki, which may also be carried out from the link on the main NIST Cloud Computing application web page.

DISA ramps up cloud-computing platform
By Joab Jackson
Oct 05, 2009
Military program managers frustrated by having to wait six months to get a server provisioned might want to take a look at the Defense Information Systems Agency's new cloud-computing offering. The agency is boasting that can provide a NIPRnet-connected, production-ready virtual server within 72 hours.
DISA announced today that it has expanded the scope of its Rapid Access Computing Environment (RACE) to incorporate production-ready services.
DISA launched RACE a year ago as a self-service environment for defense developers to provision virtual servers and test new applications in a safe environment. Now the agency has expanded the offering as a production platform.
"It's not just a test-and-development environment anymore," said Henry Sienkiewicz, technical program director of DISA's computing services. “It's also a production environment.”
All branches of the military services can provision servers through RACE for their production-ready applications. The applications that are best served by that environment are lighter ones that could run easily in a standard Microsoft Windows or Linux environment. Convoy control systems, satellite controls or even smaller command-and-control systems would work well. "It would almost be the same sort of applications that you would [deploy] within a commercial hosting company," Sienkiewicz said.
One advantage that DISA offers over commercial hosting companies is its familiarity with meeting defense security standards. In the new environment, accreditation for production systems takes only about 40 days, or about half the time it normally takes to get a new system audited and accredited for military use, Sienkiewicz said.
The agency has assembled a package for users called Pathway to Production, which includes integration with the Defense Department's Vulnerability Management System, the Enterprise Mission Assurance Support Service (eMASS) and associated documentation. DISA has also prepared the virtual environment to conform as closely as possible to the DOD Information Assurance Certification and Accreditation Process and the DISA Security Technical Implementation Guides.
DISA officials hope to cut more time from the accreditation process by further integrating RACE with eMASS and other accreditation processes. Users can also save time by developing applications right in the RACE testing environment.
"Applications developed in the RACE testing environment inherit all the information assurance controls in the production environment, and that streamlines a great deal of human intervention," which shortens accreditation time, Sienkiewicz said.
The service offers Windows Server and standard Linux, Apache, MySQL, PHP stacks. The basic service runs $1,200 per month per server. Users can provision up to 1T of storage. The provisioned servers will be accessible via the Unclassified but Sensitive IP Router Network and, beginning in the second quarter of fiscal 2010, the Secret IP Router Network.
Although DISA is using virtualization to maximize server use, end users do not need expertise in virtualization management. To them, the service appears as "a preloaded, preconfigured server," Sienkiewicz said.
Once commissioned, virtual servers can be operational within 72 hours, and agency officials hope to shorten that time to less than 24 hours. The agency has maintained an uptime of 99.999 percent with its hosted offerings and plans to offer that level of service to RACE users, Sienkiewicz said.

BLOOMFIELD HILLS, Mich.--(BUSINESS WIRE)--Lakeside Software today announced that Lakeside Software SysTrack® solutions have been awarded the Certificate of Networthiness (CoN) from the U.S. Army Network Enterprise Technology Command.
This accreditation ensures Lakeside Software SysTrack products meet strict U.S. Army and Department of Defense (DoD) standards for security, compatibility and sustainability. This enables government departments to provide automated, comprehensive pre-virtualization analysis, assessment, modeling, planning and end user experience management support for enterprises and data centers while remaining compliant with U.S. military IT standards.
The CoN is required for all enterprise software products in the Army Enterprise Infrastructure Network. The certification also applies to all National Guard, Army Reserve and DoD organizations that use the Army Enterprise Infrastructure Network.
"Government entities can realize the benefits of flexible, cost-effective virtualization assessment, planning and end user experience management to take advantage of virtualization for both VDI and server infrastructures," said Mike Spray, Director, Corporate Alliances, Lakeside Software. "The DoD certification recognizes Lakeside Software SysTrack solutions for their high scalability, manageability and security."
The SysTrack product suite addresses the full spectrum of planning and management needs involved in adoption of desktop virtualization. The process of virtualizing desktops is a complex undertaking that involves many disciplines. The market uptake of desktop virtualization is limited by the slow planning cycles typical of manual processes, slow adoption rate due to unquantified risk and overall “mystery” in achieving successful VDI projects.
Lakeside Software offers an integrated tool suite that provides VDI assessment, VDI capacity planning, virtualization modeling and predictive analysis, migration planning, storage throughput and space planning, power planning, firewall and latency analysis, user and application behavior analysis, pooled desktop / image planning and application virtualization compatibility analysis. Real-world desktop virtualization projects require multi-disciplinary analysis of a wide range of criteria to create comprehensive plans.
The SysTrack solutions deliver immediate insight into the enterprise with software features such as the SysTrack Site Visualizer that help clients identify how to maximize ROI in VDI and Server virtualization projects to align with dynamic business changes and cost reduction goals. The solution is part of the key building blocks for Lakeside Software virtualization offering, which enables clients and government agencies to capitalize on virtualization cost savings within their infrastructure.
Virtualization can work wonders for an IT environment. Virtualization lets one computer do the job of many consuming less floor space, energy and operational costs than installing more hardware. These virtual machines can be managed remotely, and can store critical data and applications for disaster recovery purposes.
But virtualization comes with a potential drawback. Specifically it introduces a new layer of software on top of the host machine or system, which creates additional infrastructure to manage and secure.
Despite security concerns, however, virtualization's here to stay. According to survey results Microsoft released in April, 71 percent of U.S. retailers use virtual tools to cut costs and gain greater infrastructure control. Experts agree other sectors, including government, will ride the virtual wave for the foreseeable future.
As virtualization becomes common, security must adapt and evolve. IT professionals should ensure they don't scale their virtual environments up higher than they can control. To obtain a manageable virtual environment, it should be built with clearly defined goals, architecture and set policies to gauge performance.
Steps to SecurityMark Ramsey, manager of IT operations for Charlotte County, Fla., said shutting down unnecessary services in the virtualized environment can help decrease cyber-attacks.
"It's probably more important in a virtualized environment, because of performance, that you eliminate unnecessary services from your servers," he said. "If you don't need Internet information services for some specific purpose on one of your servers, don't install it."
There will be less activity to protect and monitor if IT managers shut off unneeded activities. Another benefit is the network will likely run better because it will take up less processing power.
But securing a virtual network takes more than the efficient use of resources.
There are three areas that are different between virtualized and nonvirtualized environments, according to David Greschler, director of integrated virtualization strategy for Microsoft. "First, customers need to secure the virtualization layer by ensuring they are running virtualized applications on a trusted platform," he said. In other words, secure physical resources before running virtual systems on them.
Second, IT staff should isolate virtual machines, Greschler said. One way is to segment virtual machines into groups - one set running on one piece of hardware and another set running on a different piece - based on function and level of importance. This way, if one operating system inside a virtual machine is compromised, it's harder for viruses to infect systems running on other hardware.
"Third, customers must monitor virtual machine-to-virtual machine traffic so that the only communications through the network [are] where policies can be enforced and traffic analyzed," Greschler said.
Sometimes it's hard for people to track virtual machine activity. If they deploy additional virtual machines, they create another layer of machines to manage on top of the ones in their physical environment. This added virtual traffic can lead to security lapses and "blind spots" - areas people can't see in the infrastructure. It's not unusual for networks to be so vast that people lose track of which virtual machine runs what application.
This problem can be solved, but at times, it may not be that pressing of an issue.
"There are very rare cases where customers need full visibility of every sort of piece of traffic going between machines," said Nand Mulchandani, VMware's senior director of product management and marketing. In normal physical data centers, no one views traffic because it's not cost effective. "So when you move to a virtual environment, the loss of that visibility is actually not that big a deal," Mulchandani said.
Security and ManagementSuppose you're an IT manager who wants to see what happens in a section of your network. Virtual machine No. 20 is communicating
with virtual machines No. 21 and No. 22, and you want to see what packets - formatted data blocks - are being exchanged. The solution is to find an application that lets you monitor traffic and provides the visibility you need.
"There are a couple of folks, and VMware's one of them, that have built net flow interfaces, which give you the ability to view what traffic is moving between all the different virtual machines within a specific hardware enclosure," said Mike Rothman, president and principal analyst of Security Incite, an independent information security firm.
Other vendors, including Microsoft, Blue Lane Technologies and Altor Networks, also have applications designed to monitor virtual traffic. These applications let people block, stop or analyze traffic. However, with so many vendors selling security-monitoring products, it's not easy to pin down an industry leader or select a solution.
"Right now, no one vendor can solve all the virtualization issues on [the] security side," said Stefan Nguyen, a consultant for the Florida Department of Transportation who works on servers that support the central department office. Though these vendors' software solutions all promise to monitor security, they don't all do it the same way. "Each piece of software plays a [certain] role, so you can't combine everybody. That's why you have to use your own best practices."
Best practices are helpful, but sometimes customers are so in love with virtualization's benefits - cost savings and energy reduction - that best practices become afterthoughts.
"There [are] a lot of industry guidelines and platform providers' suggestions, best practices, for securing virtualized environments," said Christopher Hoff, chief security architect at Unisys. "It's amazing how many people don't do them."
Managing virtual networks is similar to managing physical ones. In fact, a good first step to securing a virtual infrastructure is securing the software that runs it. A properly configured physical network lays the foundation for a safe, properly configured virtualized one.
"I don't differentiate between my virtual and physical infrastructure," said Ramsey, who recently received certified chief information officer accreditation though the University of Florida. In Charlotte County, Fla., he has eight physical servers that run 109 virtual machines. "You apply all the same methodologies and checks and balances that you would whether you're dealing with a virtualized server or a physical server," he said.
As a beginning point, Mulchandani recommends securing the software that runs the virtualization platform.
"When you move your machine from a physical machine - say you run on a Windows server or a desktop - and you [create] a virtual machine out of it, the security products and security of your machine are unchanged," Mulchandani explained. "Meaning, if you were running antivirus software on your physical machine, it actually continues to run unchanged in your virtual machine."
Virtual World AttackersSoftware that manages virtual machines is called the "hypervisor." When installed on a host machine or operating system, the hypervisor sorts the host system's processing power and other resources to support the various virtual machines. Some experts wonder if it's a prime target for malicious programmers to corrupt or penetrate to gain access or control of scores of virtual machines.
"The probability is high that we will see exploits targeting the hypervisors," Unisys' Hoff said. "The possibility really depends upon how well these vendors do in securing the underlying hypervisors themselves."
Hoff said inevitably hackers will target virtual environments specifically, but vendors have done a decent job of securing hypervisors' underlying code.
"There haven't been any attacks against the hypervisor, so all of this talk and discussion is theoretical," Mulchandani said. "What makes it hard to attack the hypervisor is the fact that the hypervisor is actually a very small piece of code. It has few interfaces to
the outside world and does not communicate or have users checking e-mail and browsing the Web on it."
But just how do you secure the hypervisor? There are applications that reduce its attack surface, and methods include embedding the hypervisor deeper within the network or limiting the number of network channels.
Attacking the hypervisor may be worth the trouble for only the most sophisticated hacker. After all, if you're going to burglarize a house, why smash through the concrete foundation when you could break open the door or a window?
"A Windows machine running on your Dell box in your physical data center and a virtual machine look identical because they have an IP address," said Mulchandani. Consequently most hackers won't care much about the hypervisor when they can use their regular tricks to attack the machines directly.
Hoff feels the same way. "Attackers are lazy. They go after the low-hanging fruit," he said. "Why would I bother deploying virtualized rootkits when I can just essentially exploit a poorly configured server?" This takes the same amount of effort it would take to infect a system with malware once someone clicks on a link they shouldn't.
You really have to study hard. These questions are a big help and worth the price. Test Engine has specific steps which you need to follow in order to install it. But is a nice piece of software.
