j2 Update on the j2 Universal Tool-Kit, .NET 4.8, Cyber Security and Windows 10

Overall System Security and performance continue to be an important consideration when running any operating system. For security purposes it is always advisable to run the latest version of Windows and in the case of Windows 10, those improvements are extended further through Windows 10’s use of .NET Framework 4.8. To take full advantage of Windows 10 the latest version of the j2 Universal Tool-Kit, v7.0, also utilises .NET 4.8.

As part of the improved security aspects, Windows 10 and .NET 4.8 include the following improvements:

  • NGEN improvements. The runtime has improved its memory management for Native Image Generator (NGEN) images so that data, mapped from NGEN images, are not memory-resident. This reduces the surface area available to attacks that attempt to execute arbitrary code by modifying memory that will be executed.
  • Antimalware scanning for all assemblies. Starting with .NET Framework 4.8 running on Windows 10, the runtime triggers a scan by antimalware solutions that implement the Antimalware Scan Interface (AMSI).

As well as all the capability improvements in the j2 Universal Tool-Kit v7.0, there are also further performance advantages through the use of improvements in the Just-in-time (JIT) compiler.  The Just-in-time (JIT) compiler in .NET Framework 4.8 is based on the JIT compiler in .NET Core 2.1. Many of the optimizations and all of the bug fixes made to the .NET Core 2.1 JIT compiler are included in the .NET Framework 4.8 JIT compiler.
