This is a really elementary question… anyway, I’ve been lobbed into teaching some elementary cybersecurity, about which my knowledge tends to be mostly theoretical (I’ve written a book about cryptography, for example). The students, most of whom use Windows, will be running Kali Linux in a virtual environment such as VirtualBox. I need the easiest possible way of making a site available to them so that they can have a go at experimenting with SQL injection attacks in an ethically appropriate manner. What’s the best way of doing this? I’m looking for something as simple and as fool-proof as possible – given that I anticipate much confusion. What is the recommended approach here? Many thanks.
