Manage non-vendor-supported products (e.g., end of life) separately and restrict as necessary to reduce risk.

It is inevitable for products such as software and operating system to reach their end of life. At this phase the vendor no longer releases security updates. An example is Windows 7. Because these systems can no longer be patched they are at higher risk of compromise. This risk can avoided by decommissioning the system or ir can be mitigate with additional security controls.

Either decommission or isolate systems that have reached their end of life (no longer supported by the vendor). Example include old operating systems and software applications.
