If your company still has systems running Windows XP, here are some important security tips. Solution providers that work with embedded systems, such as ATM machines and point-of-sale terminals, should be checking in with longtime clients and upgrading systems. If the solution providers do not let the smaller merchants know that Windows XP is going into retirement, then they may unknowingly continue using outdated and poorly maintained equipment. This could cause major security issues. The good news is that most banks and payment processors monitor their customer base to address problems.
The programs will help protect against attacks targeting the browser, its components and other applications, but these antiviruses will not detect attacks that target vulnerabilities in the operating system.
The anti-malware utility checks Windows XP systems for infections and can help administrators remove malware. Windows XP supports Data Execution Prevention, a feature that attempts to prevent exploits from executing in memory. Unfortunately Windows has made for security measure available on newer OS that make the attacks less likelyon those systems and more likely on Windows XP. The Enhanced Mitigation Experience Toolkit can be enabled to help prevent memory corruption vulnerabilities from executing on the system.
The tool may be too complicated to deploy and maintain on dozens of PCs, but on fewer systems, it would be manageable, say solution providers.
Once it ends support on April 8, Microsoft will not be issuing any patches for the operating system, leaving the potential for open vulnerabilities.
The only time an exception might be made is if a quickly spreading attack had the potential to cause serious problems, say security experts. Microsoft researchers collected a sample of application exploits that had been sent to Microsoft from customers worldwide. All exploits targeted vulnerabilities in popular applications running on one or more versions of Windows. Note that none of the exploits tested, attempt to exploit vulnerabilities in Windows — they all attempt to exploit vulnerabilities in applications running on Windows.
Figure 8 shows the results of these tests. The data suggests that system administrators can significantly reduce their attack surface now by upgrading to the latest versions of their operating system and application software or by deploying EMET, or both. Until recently one of the biggest obstacles to using EMET in large environments was deployment — it was challenging to scale across thousands of systems.

All but three of the exploits tested succeeded on Windows XP in this configuration. Again, all of the exploits tested were designed to exploit applications, not Windows operating systems. Ten of the exploits tested succeeded on Windows 7 RTM. Free resources to help: EMET version 3.

The last 18 months have put pressure on organizations to speed up their digital transformation as hybrid work continues to become the new normal. Yet even with all the change and uncertainty, having the right security support system in place means your organization can still move forward confidently to turn your vision into reality.
