Member Batye recently reviewed Stealing the Network: The Complete Series Collector’s Edition for our Bookworm Blog. It’s a collection of fictional stories that takes a look at the possibilities available to hackers with some time and bad intentions. While the collection is meant to be an aid to ethical hackers and security professionals looking to be proactive, it brings up a moral dilemma. How can you ever ensure that the knowledge you’re passing on will be used for good rather than evil?
A question was recently posted in the IT Forums regarding embedding executable files into a JPEG, a common tactic for spreading malware to unsuspecting end users. The community responded with mixed feelings toward the intentions of the asker. Who draws the line between helping out your fellow IT professionals and providing ill intent with the recipe for possible harm?
The simple answer is that no one draws that line except for you. IT Knowledge Exchange doesn’t expect you to provide any information you feel uncomfortable disclosing, and that goes for answering deceivingly innocuous questions. Member Chippy088 shares his own philosophy on the dilemma:
[It’s] not a good idea to help everyone without thinking about their reason for the question first.
Have there been circumstances in your tech career that have made you uncertain about passing on your own knowledge? What are some nuggets of advice you’d want to pass on to those who are new to IT Knowledge Exchange or IT in general?
Despite the progress SaaS has made in the enterprise, security concerns remain a hindrance to the growth of the market. Enter former Salesforce.com executive, Tod McKinnon, now CEO of Okta, with a lofty goal: To accelerate enterprise adoption of cloud and web-based apps.
All the ROI in the world doesn’t mean a thing if your mission-critical apps are a floating security risk. As McKinnon told Newsfactor.com, “Okta is the only enterprise-class, on-demand service purpose built to help customers secure and manage their entire cloud-services network and the people who need access to it, with no professional services required.”
While cloud computing isn’t necessarily moving IT security into uncharted waters, it is highlighting some old vulnerabilities that many organizations just never got around to patching up, from shoddy encryption practices to allowed poor user practices. Leading the way, in both stumbles and recoveries, might be Facebook, which probably has its own recent security struggles more closely watched than any other company.
Phishing for fame and friends
Today, most attacks on corporate infrastructure are driven by monetary gain: Long gone are the days where embarrassing defacements dumped a company’s dirty laundry and embarrassing taunts onto its domain. Instead, the criminals are largely organized, stealthily going in and making off with the valuable digital loot without being noticed until it’s far too late. Facebook still sees its share of these types of criminals. However, its high-profile nature, and mixed track record on privacy, has made it a favored target for the type of attacker who still likes to put on a show. Nicolas Sarkozy’s account was recently hacked, posting a message stating the president would not seek office again (he has made no official statement on his plans). Facebook founder Mark Zuckerberg then had his fan page hacked, pleading for the company to become a ‘social business.’
Application security company Veracode is demonstrating to developers how easy it is to test and identify vulnerabilities in their applications by granting free access to one of its services. Veracode’s offerings include automated binary analysis in the cloud and as of today, developers can register to upload one application to the cloud and test for cross-site scripting (XSS) vulnerabilities at no cost. XSS, a common security exploit where attackers put malicious coding into a link that releases itself when a user clicks the link, is a veteran problem in application development and responsible for major security breaches.
Veracode hopes to demonstrate how avoidable XSS vulnerabilities are while highlighting their application security testing offerings, boasting their ability to serve both SMBs and large organizations. Most development oversights are minor, but can have major repercussions, which is why Veracode is doing its part to aid in the “long road to eliminating XSS.” In a recent blog post, application security researcher at Veracode Chris Eng likens fixing XSS vulnerabilities to squashing ants, but that doesn’t mean the problem isn’t major just because its solution can be:
At Veracode, we see thousands — sometimes tens of thousands — of XSS vulnerabilities a week. Many are of the previously described trivial variety that can be fixed with a single line of code. Some of our customers upload a new build the following day; others never do. Motivation is clearly a factor. Think about the XSS vulnerabilities that hit highly visible websites such as Facebook, Twitter, MySpace, and others. Sometimes those companies push XSS fixes to production in a matter of hours! Are their developers really that much better? Of course not. The difference is how seriously the business takes it. When they believe it’s important, you can bet it gets fixed.
In a climate that’s teeming with new security threats every hour, a company’s security priority list can be the difference between a close call and a major setback. Proactivity is key. There’s no such thing as a free lunch, but when a company is offering free security testing, it makes reprioritizing not only appealing but affordable. What does your company have at the top of its security priority list this year? Do you anticipate taking application security testing in the cloud for a spin? Let us know in the comments or send me an email at Melanie@ITKnowledgeExchange.com.
It’s been a pretty busy month around IT Knowledge Exchange, and we’ve learned a lot about desktop virtualization. We’ve compiled some of the highlights to serve as your go-to list for some of the top considerations from planning to deployment.
Blogging About Virtual Desktops

Twitter is bursting at the seams with virtual desktop experts and enthusiasts. Take advantage of your chance to interact and ask questions. If you’re still stumped, head over to IT answers, and be sure to tag your question desktop virtualization.
Not a fan of Twitter? Don’t worry, we’ve got an impressive list of virtual desktop blogs for you, too.
We’ve always got some good discussions happening in the forums. Here are some of the top discussions and questions from desktop virtualization month:
- Virtual Apps vs. Virtual Desktops: Member Juttej is exploring options for a 600 PC network project. Rechil and KFaganJr shared some of their own experiences with the two options while Pjb0222 gave some questions to consider during planning.
- Open IT Forum: Who is deploying desktop virtualization?: Mortimer1, Batye, Carlosdlg, and Rechil discuss what their companies are exploring as far as virtualized desktops go. It’s a great look into the inner workings and conversations that happen when an enterprise is considering desktop virtualization.
- Which is better: Microsoft App-V or Citrix XenApp?: Mortimer1 gives a good rundown of what situations are ideal for each product.
- Suggestions for desktop virtualization resources: From books to hardware, check out some of the community’s suggestions.
Brian Madden, Gabe Knuth, and SearchVirtualDesktop.com editor Bridget Botelho sit down and discuss their hopes and predictions for desktop virtualization in 2011.
VDI is no small undertaking, so be sure to avoid some of the common VDI deployment problems.
Amazon’s cloud empire floated a little higher yesterday with the announcement that the web giant is adding bulk messaging to its cloud services. From the announcement:
We’re excited to announce the beta release of Amazon Simple Email Service (Amazon SES), a highly scalable and cost-effective bulk and transactional email-sending service for businesses and developers. Amazon SES eliminates the complexity and expense of building an in-house email solution or licensing, installing, and operating a third-party email service. The service integrates with other AWS services, making it easy to send emails from applications being hosted on services such as Amazon EC2. With Amazon SES there is no long-term commitment, minimum spend or negotiation required – businesses can utilize a free usage tier, and after that, enjoy low fees for the number of emails sent plus data transfer.
The horizontal play isn’t particularly surprising. While e-mail is something Amazon has been supporting via EC2 instances, the results aren’t always pretty. The dynamic IPs, for example, often get Amazon-powered e-mail flagged as spam. A dedicated service will help push past these problems, particularly for businesses where e-mail is an important tool but not necessarily the prime competitive advantage, leaving one less thing for your average IT department to puzzle through.
Who says the big guys never make room for the little guys? Whoever they are, IBM is making them think again with its latest offering suited for small- to medium-sized businesses: IBM Virtual Desktop for Smart Business. Using the Virtual Enterprise Remote Desktop Environment (VERDE) software from Virtual Bridges, IBM’s offering provides connection to Windows or Linux desktops for numerous devices. Enterprises have several options with Virtual Desktop for Smart Business: Windows XP or Windows 7 operating system, Linux (Ubuntu, Red Hat, Novell), and deploying on existing infrastructure or through an IBM reseller host.
The requirement for devices to access the desktop? If your device is capable of connecting to the server via a browser, you’re in. VDI, IT’s latest buzz acronym, appears to be stumping enterprises big and small. Aimed at companies from 100 to 1,000 end users, IBM’s virtual desktop offering provides VDI without the complexities SMBs can’t afford to navigate for just $150 per user, per year. The service is available through IBM’s approximately 100 resellers and integrators around the world.
Not quite as simple as Kaviza’s VDI-in-a-box offering, IBM’s virtual desktop requires configuration, design, and installation. The VDI package runs on IBM System X server running Suse Linux and VERDE, altogether with the capacity for up to 200 desktops on a server.
The offering is exciting for the desktop virtualization market for a couple reasons. Continued »
Virtualization hulk VMware closed out 2010 with a bang, reporting a 37.4 percent increase in revenues at $835.7M, and a 212.5 percent increase in net income at $119.9M.
Desktop products such as VMware’s View and the Workstation hypervisor accounted for 10 percent of revenues for the full year in the United States, a possibly deceptive figure in the face of the prevailing hope that 2011 will be a big year for desktop virtualization, particularly virtual desktop infrastructure. VMware’s chief financial officer, Mark Peek, didn’t make any predictions in that arena, but TechTarget’s own virtual desktop experts Brian Madden and Gabe Knuth took a stab at foretelling desktop virtualization trends in the coming year, marking VMware’s Horizon as a major competition for Citrix’s OpenCloud Access.
VMware as a whole is projecting modest growth in 2011, between $800 and $820M for Q1. Acquisitions were a major part of VMware’s 2010 strategy, with seven in total, adding upwards of 600 employees. VMware finished off the year with around 9,000 employees worldwide, up from 7,000 at the start of the year.
With pre-installation of vSphere on servers from big name hardware makers such as HP, Dell, and IBM, VMware is in good standing for a strong 2011.
What are your predictions for desktop virtualization in 2011? Do you think VMware will continue to reap the benefits?
Today’s guest post comes from Michael Fox, author of DeMystifying the Virtual Desktop. Michael Fox is a practicing expert working in the field of desktop virtualization. He has worked in IT for more than a decade, holds numerous technical certifications, speaks regularly at technical conferences and currently works as a Senior Architect in virtualization for EMC Consulting, the professional services division of EMC.
My hope for 2011 is that I have fewer meetings introducing people to the basics of desktop virtualization and more meetings about advanced topics in the field. I want to have more meetings on the kinds of desktop virtualization topics that allow us consultants to flex our muscles, bringing the considerable weight of our practice’s talent to solve an organization’s challenges. I want to have CIOs ask me how we can baseline the existing compute experience and then, using desktop virtualization, improve productivity for employee workflows. I want to have VPs considering acquisitions asking me questions about how desktop virtualization can accelerate the time it takes to complete integration.
If everyone read my book, that might happen. I wrote DeMystifying the Virtual Desktop to be a resource that gives decision makers an introduction to the use and application of the technology. It covers the basics of desktop virtualization like putting the user first, communicating across teams, understanding foundational technologies, doing assessments and analyzing designs to help understand costs. It was peer-reviewed and written in a completely agnostic way that does not mention any specific technology or vendor.
According to a number of studies that are out there, a large number of organizations have only just begun looking at this powerful technology. The good news for those of you just beginning your virtual desktop journey is that the products and reference architectures are getting better all of the time. Density inside the data center is increasing and the competition between platforms is quite healthy. There were so many improvements in 2010 that they are difficult to count. Protocol improvements enabled improved access to virtual desktops inside the data center. A number of new features, both hardware and software, are eliminating the storage challenges with centralized deployments. Lastly, the promise of the client-side hypervisor, with its centralized administration and decentralized execution, is beginning to come true.
Watch for a number of exciting new desktop virtualization developments in the coming quarters. I can’t say anything because of those pesky non-disclosure agreements, but there are a few real gems out there that I am really looking forward to bringing up with customers – the kind of developments that enhance the usability and value of desktop virtualization technologies for both end users and administrators. Density will continue to do what it does best – increase. Application performance will continue to advance to levels that are quite significant. Architectures that support sub second application startups, for example, will continue to become more and more common. There is even progress on desktop certifications. AppSense has two new certification tests coming to a testing center near you in February.
What we all know for certain is that 2011 will continue to be a year of conquering virtual desktop implementation challenges. Enterprises that implemented the technology early on will be considering ways to take advantage of new storage and application virtualization techniques. Companies performing Windows 7 migration will continue to consider desktop virtualization technologies at the same time. A change from 2010 will be the slew of tablets that are going to be invading our enterprises. This may in fact be a boon to the entire desktop virtualization space. If you think about it, the tablet and the virtual desktop may be a match made in heaven by giving users the ability to access any kind of application and/or an entire corporate desktop from the convenient devices.

In the hubbub of new year’s predictions, Security Week expects virtualization to take a step forward in 2011 despite general security concerns:
Many companies have cited security concerns as the main blocker to virtualization and private cloud adoption. Paradoxically, virtual machines can be more secure than the physical servers they replace. Because virtual machines are purpose-built, virtualization security software can offer levels of dynamic and automated security that are unequalled in the physical security realm. As organizations become more familiar with hypervisor-based security and VM Introspection, the apprehension that may have stymied virtualization of critical workloads will be appeased.
Rather than having numerous endpoint devices that increase the possibility of a rogue user or machine, aspects of desktop virtualization such as zero clients allow for a major decrease in the threat of human error. As a result of the lessening of security fears surrounding the technology, IDC analysts predict revenue of $1.7 billion by 2011 in the desktop virtualization market. Gartner, similarly, predicts an increase in desktops virtualized from 500,000 to 49 million by 2013. Now that desktop virtualization is becoming more of an accepted technology, you should know your options by asking yourself some questions.
