Information security VS Information Technology
Try to emphasize that while the two disciplines are similar sounding, their vision, mission, curricular framework and competency frameworks are different. How a degree in information technology is a generalist degree, providing a student with understanding of broad and fundamental computing subjects such as programming, databases, networking, human-computer interaction and web systems while a degree in information security is a specialist degree focusing on information security. You can also stress how mobile applications, enterprise computing, social platforms, internet of things and cybersecurity have lead to the creation of a separate, specialized curriculum, viz, information security. If there are specific careers that a degree in information security prepares (Cyber Security Architect, Information Security Architect, Good Governance Architect, etc) that a person with a degree in IT would be generally unable to fill, you can specify that as well.
