Cyber Security and Digital Forensics- What should I learn?Watch
With that out the way:
For the Forensic part. Look at software like Encase (paid) and Autopsy (free) they are software that allow you to securely analyse an image e.g. a hard disk image or usb image etc. Other 'cyber' software. Look at FTK imager and KAPE.
Also look at legislation and the UK legal system. Why? Well, once you done the fun part of digging up the crime on a hard disk. You have to learn how to make write a report with legal information in a non-biased way. Go to a website like Westlaw UK and learn what the abbreviations mean in case titles. Don't use the search bar, learn how to use the filter search functions.
Other things would be just understanding what encryption is, look at cryotpgprahy, and software used for penetration testing. Also get a grasp on using Linux operting systems and running commands from the command line. Kali Linux has a lot of fun preinstalled tools for pen testing. You can run these operting systems virtually with Oracle Virtual Box (google it).
I'm not sure if USW or UoC have databases in their courses but if so certianlly learn the fundamentals of making databaes e.g. design and how to use Oracle SQL. Once you know how a database works you'll know better how to secure it from things like SQL injections among other attacks and security pratice.
You will probably have to do some programming whatever uni you goto. Learn C++. Why C++? Well other than making game engines and operting systems, cyber forensics is the other place its widely used and once you grasp the concepts of programming in C++ you can apply those to other languages with more ease.
