Security is the top priority for any organization and system. A legacy application that runs on an old operating system (such as Windows XP or Windows 2008) is more vulnerable to security issues due to lack of vendor support. Software vendors continuously determine new security threats and release patches to accommodate them in the latest software version, to secure them. Any legacy software that is announced as End of Life (EOL) from a vendor doesn't get a new security patch, which leaves your application running in the old software version, exposed to a number of security threats.
System health checks are often ignored for legacy applications, which make them more vulnerable to security attacks. The skills gap makes it difficult to provide continuous support and help, which means systems are run in an insecure manner.
