Sometime OS-level encryption is just not enough, from time to time all of us need to copy a VM to a non-encrypted external disk or a flash drive. Then, after the copy is made, all the hard work and all the security measures go out the window, that’s because when copied, our sensitive data is free to access for anyone who can get hands on that drive. What can be done to create an extra layer of security and help us in this situation? That’s right, you’ve guessed it, it’s VM Encryption, let’s have a quick look at how you can enable it in VirtualBox.
Recently I had to create a new VM with CentOS on it and thought that I could write these things down to help myself in the future. Hopefully, these notes will help you too 🙂
