Breezing through the terminology won't help, it might be difficult for them to recall all the terms and they might not truly understand the importance without seeing practical examples. And if it is the first time it will be done, I suspect it should go well, with good review and grades. If they're not CS students, I would say you need to keep it simple. I would go with basics such as:
- email security - spamming, phishing, scams;
- physical security - dumpster diving, tailgating;
- social engineering and how it can be used;
- passwords/ passphrases and only high level hashing maybe;
- OWASP, STRIDE, CIA triad, AAA (triple a);
- browser security - such as how can they know if something they download is secure or not, certificates - not technical details, but basics so they can know if a site is secure, http vs https;
- digital signing and encryption (not in depth, maybe its importance and something like caesar cipher they can play with so it will be fun for them, not complex stuff) and so on.
But for each of these topics, I wouldn't stick with the terminology, I would try to show them examples using images/ demos.
If it makes sense, let me know and maybe I can provide help or online resources where you can look for these kinds of topics.
There is a security certification meant to cover the basics, it's called CompTIA Security+. Of course, you don't have to take the certification. But if you look for its requirements, you will find a list of topics that might be of interest for you. It has a wide range of modules, from absolutely zero knowledge to basics for CS people. You don't have to cover the ones that seem more technical, for your purpose. The resources to learn for this certification for sure contain what you need. The best resources I can recommend you are the following:
- Dariil Gibson's book - Get Certified Get Ahead,
- Professor Messer videos (this one is free),
- Pluralsight website - CompTIA Security+ the 501 Path (if your University provided you access to Pluralsight; or if you have Microsoft Student Partner organization at the University they might be able to provide you free access, though I cannot guarantee).
You don't have to cover all of them. I found the videos more easy going, and the Pluralsight ones more structured and concise. If you prefer to read a book, that one should be helpful.
