Popular Cyber Security & Networking Acronyms

Thanks in part to IBM, no field uses acronyms like computer science. Recently I was asked to pick up product management responsibility for an evolving new line of cybersecurity products. To be relevant one needs to be current with the trendy lingo, as such here are some of the must-know acronyms. So if you’re a budding cyber security student, or hacker in training see how many of these you know off the top of your head. Note, every one of these has been checked, and the full expansion of the acronym links to the appropriate Wikipedia page.  Good luck, and enjoy.
