How can IT Infrastructure Library (ITIL) improve information security?

The ITIL change management process is one of the very important processes that helps increase security for IT applications and infrastructure. For example, in healthcare and hospital environments, maintaining an eHealthRecord (eHR) application is an enormous IT task. Cerner, Epic, Allscripts, MEDITECH, Siemens and McKesson are the major vendors and cost many millions to purchase. It often requires millions more in resources to implement and maintain.The ongoing task of maintaining a hospital eHealthRecord is a giant burden on IT. There are also many possible security issues, given that HIPAA compliance is required for any hospital or healthcare environment. According to industry research, some hospitals have a backlog of over 1000 eHealthRecord Requests for Change (RFC), and many are related to security.
