Microsoft Windows 7 and Windows Server 2008 reached end of life on January 14, 2020. This means that Microsoft will no longer be releasing free security patches, updates, or support when something goes wrong. Although these operating systems won’t instantly stop working or become security risks overnight, there are risks with staying on these operating systems for an extended period of time. What happens if I stay on these operating systems? There is a huge risk of being exploited by cyber crimina... read more.

Perhaps one of the most popular features of Exchange is the ability to connect Outlook running on a PC to Exchange over the Internet when outside the corporate network without the need to establish a VPN connection. This feature was introduced with Exchange 2003 and is called Outlook Anywhere. Of course, convenience always comes at a price: once enabled, Outlook Anywhere allows anyone with Outlook to connect to Exchange from any PC regardless of who owns it. Many organizations want or need to restrict Outlo... read more.

Microsoft has officially released their Desktop as a Service (DaaS) offering, dubbed Windows Virtual Desktop (WVD). There are some standout features of WVD, and as someone who’s been helping customers deliver Windows desktops and applications for 20 years, I feel a strong market momentum behind this offering. Microsoft is making WVD very attractive, starting with a unique multi-session version of Windows 10 which is only available in Azure through this offering and continuing with extended support for... read more.

A common issue I see in Citrix Virtual Apps and Desktops deployments is users who are unable to print to their local printers from Mac and Linux clients when using Citrix Universal Printer Driver (UPD ). The good news is, it is a very simple fix! Citrix UPD relies on a series of printer drivers to be installed on the VDA machine. When a client printer is mapped into a session, it is automatically mapped to one of these three drivers: The Citrix Universal Printer and Citrix XPS Universal Printer drivers... read more.

One of the most common attack vectors for cloud servers is through Remote Desktop Protocol (RDP) or Secure Shell (SSH). When administrators build servers in the cloud, Microsoft and AWS had typically assigned a public IP to ease management of the servers. There is no VMware Console equivalent in the cloud, so RDP or SSH are the only way to manage a server. The problem starts when that public IP is assigned. Hackers are constantly running scans on the IP ranges owned by the cloud providers, and as soon as a... read more.

Splunk is shining its light on Dark Data and enabling companies to extract real business value from their machine data. As the value of that newly exposed information increases, it is important to be able to access it from anywhere, even from mobile devices. Although a Splunk mobile app has been available for a few years, connecting to an on-premises Splunk Enterprise deployment was difficult. The mobile device needed some type of VPN software to access Splunk dashboards, or there were more complicated meth... read more.

Subscription-based pricing is all the rage and I think there are some gaps regarding expectations all around. Let’s start with the math and we’ll end on philosophy. Traditionally, you might buy a piece of software for say, $100K. You would generally pay about 20% a year in maintenance, $20K. If you were amortizing this expense over five years this would be like a $40K a year budget impact ($20K amortization plus $20K maintenance). Easy enough, if the subscription price of this software is less... read more.
