So as a cyber security intern, it's great to have a technical background. I have an ECE background (electrical and computer engineering), which helps me understand almost all aspects of how the vehicle and security that goes into place will coexist. I work in vehicle security, which is securing the vehicles from being hacked, so it's great to have the product development background too.
There are many factors that go into cyber security, including research, planning, embedded systems (ECE), developing (compSci, ECE), penetration testing (ethical hacking, they teach you how to do this), hardware security (ECE), and incident response.
My best advice that I have to offer is if you want to do cyber security, go into electrical/computer engineering. This will broaden your options to SOOOOO many great things not only in cyber but in product development, where you can work in embedded systems and develop the secure coding in the chips. You can work in all aspects of cyber, and by 2022 there will be almost 2 million job shortages. This will allow one to be a technical specialist within the cyber security field, which is very high on the food chain.
Another qualification that I can say would be good is to do independent research and try to obtain cyber security certifications. This will allow one to say in an interview that they know how to Pen Test a device, or even the process of pen testing and just be somewhat knowledgeable about the subject, and with an ECE background of knowing the ins and outs of embedded systems, it will be hard not to offer the candidate a job. But, if ECE isn't your thing, I would recommend CompSci or information systems, although with an IS degree you'll need to have a broad cyber security knowledge beforehand.
