End of Life Softwares
End-of-life (EOL) software is software that is no longer supported by its developers, meaning it will not receive updates, patches, or fixes. This can make the software vulnerable to security vulnerabilities, incompatible with newer technologies, and susceptible to operational disruptions. EOL is also known as end-of-support (EOS).
To reduce the risks and costs associated with EOL software, it's best to replace it before it reaches EOL. However, finding EOL dates and locating obsolete products can be time-consuming. MS-ISAC offers a list of EOS software dates that can be downloaded, and members can also receive alerts about EOS software.
If it's not possible to replace the software before it reaches EOL, it can still be secured by isolating it from the main network. This can be done by configuring firewalls to block traffic to and from the network segment of the software, or by establishing virtual local area networks (VLANs) or separate physical network segments.
