Designing a virtual desktop environment? – #XenDesktop, #Citrix
This is a good blog post by Niraj Patel.
Questions: How do you successfully design a virtual desktop solution for 1,000 users? How about 10,000 users? What about 50,000 users? What are the questions you should be asking? Most importantly, where do you start?
Answer: Hire Citrix Consulting for your next virtual desktop project! OK, that is one right answer, but not the only way to do it. The successful way to design a virtual desktop environment is to follow a modular approach using the 5 layers defined within the Citrix Virtual Desktop Handbook. Breaking apart a virtual desktop project into different layers provides a modular approach that reduces risks and increase chances for your project’s success no matter how larger you’re planned deployment is. What are the 5 layers and some examples of the decisions are defined within them?
- User Layer: Recommended end-points and the required user functionality.
- Access Layer: How the user will connect to their desktop hosted in the desktop layer. Decisions for local vs. remote access, firewalls and SSL-VPN communications are addressed within this layer.
- Desktop Layer: The desktop layer contains the user’s virtual desktop and is subdivided into three components; image, applications, and personalization. Decisions related to FlexCast model, application requirements, policy, and profile design are addressed in this layer.
- Control Layer: Within the control layer decisions surrounding the management and maintenance of the overall solution are addressed. The control layer is comprised of access controllers, desktop controllers and infrastructure controllers. Access controllers support the access layer, desktop controllers support the desktop layer, and infrastructure controllers provide the underlying support for each component within the architecture.
- Hardware Layer: The hardware layer contains the physical devices required to support the entire solution, and includes servers, processors, memory and storage devices.

Latest Security Intelligence Report Shows 24 Percent of PCs are Unprotected
Interesting and scary facts from Microsoft… why not just add a simple cloud based solution like Webroot to your PC’s and Mac’s? Read more about Webroot that I think is a great product here from one of my earlier posts: 1st Test of Webroot SecureAnywhere – #Webroot, #SecureAnywhere, #BYOD
Today, Microsoft released new research as part of its Security Intelligence Report, volume 14, which takes a close look at the importance of running up-to-date antivirus software on your computer. The research showed that, on average, computers without antivirus software are 5.5 times more likely to be infected.
Antivirus software from Microsoft, McAfee, Symantec and others helps to guard against viruses, remove infections and protect your privacy. It can help protect your computer from malware trying to steal your credit card information, e-mail address book or even the files you’ve saved to your computer. It is one of the most crucial defenses computer users have to help protect against cybercriminals.
If you have been using computers as long as I have, long before almost every device was constantly connected to the Internet, you’ll recall the days when viruses were typically spread via sneaker-net, through infected floppy disks. Read more…
#Citrix transfers #Xen to the #Linux Foundation – via @scottjcutter
 |
In 2007 Citrix acquired XenSource gaining control over the development of the Xen Hypervisor part of the Xen project. Today Citrix announcedthat it will hand over the Xen Project to the Linux Foundation which will continue its development. After both Ian Pratt and Simon Crosby who came from XenSource left Citrix to start their company Bromium, Citrix has clearly been struggling on how to continue its involvement in the development of the Xen project, leading to this decision.
The following companies will contribute to and guide the Xen Project as founding members of the Collaborative Project at The Linux Foundation: Amazon Web Services, AMD, Bromium, Calxeda, CA Technologies, Cisco, Citrix, Google, Intel, Oracle, Samsung and Verizon.
Its interesting to note that the Linux Foundation also supports the Kernel-based Virtual Machine (KVM) development, the hypervisor included in…

Demystifying Citrix Excalibur Architecture – via @kbaggerman
A great blog post by Kees Baggerman! 🙂
For all XenApp admins and consultants out there Project Avalon will bring a big change as we are used to having XenApp servers running on the (what seemed to be) everlasting Citrix Independent Management Architecture and we’re heading to Citrix FlexCast Management Architecture (already included in XenDesktop at this moment) and will be included in the Citrix Excalibur Architecture.
IMA
When looking up IMA in the eDocs you’ll find:
Independent Management Architecture (IMA) is the underlying architecture used in XenApp for configuring, monitoring, and operating all XenApp functions. The IMA data store stores all XenApp configurations.
Basically IMA exists to manage the XenApp or Presentation Server farms by enabling the communications between servers. As stated it transfers information about all XenApp functions like licenses, policies, sessions and server loads. All management tooling within these versions of Citrix’s PS/XA rely on this service for information.
According to Communication ports used by Citrix Technologies IMA uses the following ports:
| Ports | Source | Prot. | Comment |
| 2512 | Common Citrix Communication Ports | TCP | Independent Management Architecture (IMA) |
| 2513 | Access Gateway 5.0 Controller administration | TCP | IMA-based Communication |
As we can see IMA uses 2512 (by default) to communicate with other servers and the Access Gateway Controller uses 2513 (by default) for IMA-based communication. The port IMA uses can be changed or queried via the commandline tool IMAPORT.
Brian Madden did a blogpost way back in 2007 but it’s definition of IMA is still current:
Independent Management Architecture is:
- A data store, which is a database for storing MetaFrame XP server configuration information, such as published applications, total licenses, load balancing configuration, MetaFrame XP security rights, and printer configuration.
- A protocol for transferring the ever-changing background information between MetaFrame XP servers, including server load, current users and connections, and licenses in use
FMA
With the introduction of XenDesktop we got a new architecture called Flexcast Management Architecture. This new architecture has got an agent-based setup where we can install the operating system including the basic applications that need to be installed and after that we can install an agent. This agent registers itself to a controller and is offered through StoreFront to the end user.
This will be delivered by two different types of agents, one to support Windows Server OS’s and one for Windows Desktop OS’s.
Andrew Wood did an article on Excalibur and used this diagram to explain the architecture:
Citrix FlexCast Management Architecture
- Receiver provides users with self-service access to published resources.
- StoreFront authenticates users to site(s) hosting resources and manages stores of desktops and applications that users access – Web Interface as a platform is essentially resting, but it will cease to be.
- Studio is a single management console that enables you to configure and manage your deployment, a dramatic reduction over the 23 consoles you could well have today. Studio provides various wizards to guide you through the process of setting up an environment, creating workloads to host applications and desktops, and assigning applications and desktops to users.
- Delivery Controller distributes applications and desktops, manages user access, and optimizes…

Report: Android malware doubled in 2012, infecting 33M devices
Malware attacks on devices running Google’s (NASDAQ:GOOG) open-source Android mobile operating system more than doubled in 2012, security solutions firm NQ Mobile reports.
 |
| NQ Mobile saw a year-over-year increase of malware of 163 percent. |
NQ Mobile discovered 65,227 new pieces of mobile malware in 2012 compared to 24,794 in 2011, a year-over-year increase of 163 percent. Among all new malware discovered last year, 94.8 percent of threats were designed to attack Android, compared to just 4 percent targeting rival open-source platform Symbian. In all, more than 32.8 million Android devices were infected in 2012, up from 10.8 million in 2011, representing an increase of more than 200 percent.
Chinese devices accounted for 25.5 percent of infected Android devices, followed by India (19.4 percent), Russia (17.9 percent), the United States (9.8 percent) and Saudi Arabia (9.6 percent). Fifty-three percent of U.S. Android owners have installed a mobile security app on their device, NQ Mobile adds.
Sixty-five percent of mobile malware discovered in 2012 falls into the category of Potentially Unwanted Programs–e.g., root exploits, spyware, pervasive adware and Trojans (surveillance hacks). Twenty-eight percent was designed to collect and profit from a user’s personal data, and 7 percent was built to prevent the user’s device from functioning properly.
The primary methods for delivering malware in 2012 included App Repackaging (adding lines of malicious code into a legitimate app and reloading it onto a third-party marketplace), Smishing (asking consumers to click on a fraudulent link, triggering a malicious app download or directing their browser to a rogue website) and Malicious URLs (redirecting the browser from genuine websites to clone sites intended to collect personal data).
Critics maintain Google has failed to sufficiently police its Google Play digital storefront, making it easy for attackers to distribute malware via Android applications. Google has made strides to reduce Android threats, however: In early 2012, it unveiled Bouncer, which scans Google Play for malicious apps, and its Android 4.2 OS update, a.k.a. Jelly Bean, bakes in application verification tools.
