Gartner offers ten best practices for organizations still running Windows XP

Windows XP may have reached its end of support deadline on April 8th, but that doesn't mean the topic of Windows XP will go away - just yet. The analysts over at Gartner are estimating that one third of enterprises currently have more than 10% of their systems running Windows XP. 

Gartner is offering ten best practices for organizations still running Windows XP, in an attempt to reduce the risk of using these systems to a tolerable level. "Any system, supported or not, carries risk. For the majority of use cases, XP can continue to be used with the risk managed to a tolerable level, without requiring the enterprise to pay Microsoft for expensive custom support while migrations are completed. While doing nothing is an option, we do not believe that most organizations (or their auditors) will find this level of risk acceptable," Gartner explained.

If organizations are unable to pay Microsoft for support, or even upgrade to a modern operating system, these ten best practices should be adhered to. Here is the complete list from Gartner:

  • Restrict Network Connectivity to the Minimum Possible: Protecting XP systems is easier when other systems can't communicate to them over the network, the primary vector for attacks.
  • Implement an Application Control Solution and Memory Protection: This can be accomplished using a dedicated solution, a host-based intrusion prevention system (IPS), or Microsoft's Group Policy object (GPO)-based software restriction policies to establish a "lockdown" posture for XP to prevent the execution of arbitrary code.
  • Remove Administrative Rights: This should be mandatory for all remaining users on Windows XP.
  • Address the Most Common Attack Vectors - Web Browsing and Email: Remove Web browsing and email software from XP systems, and provide these capabilities from a server-based system that is up to date.
  • Keep the Rest of the Software Stack Updated Where Possible, Including Office: Vendors of other software solutions and versions running on these XP systems may continue support. This further minimizes the vulnerable surface area that can be attacked.
  • Use a network or host-based IPS to Shield XP Systems from Attack: Confirm that your IPS vendor will continue to research vulnerabilities and attacks on XP and provide filters and rules to block these attacks where possible.
  • Monitor Microsoft: Microsoft will not publicly disclose if new vulnerabilities against XP are discovered (unless you have paid for custom support). However, pay particular attention to critical vulnerabilities that affect Windows Server 2003 as these will likely impact XP.
  • Monitor Community Chat Boards and Threat Intelligence Feeds: Third-party threat intelligence feeds are an independent source of information. Communities of interest are expected to emerge specifically for sharing information related to XP.
  • Have a Predefined Process Ready If an XP Breach Occurs: Have a plan to isolate XP workstations in the event of an attack that gains a foothold by quarantining these systems from a network perspective until mitigating steps are understood.
  • Perform a Cost/Benefit Analysis: The cost and resources to implement the steps above might be better spent in accelerating the migration of the remaining XP systems, or it might be simpler to pay Microsoft for custom support.

How do you feel about these best practices offered by Gartner? Are they practical in an organization? Should organizations pay Microsoft for continued support or actually take a step forward and upgrade to a modern operating system? Discuss in the comments below!
