Don Murdoch How do you gain defender skills? Do you know exactly how the offense should inform defense? Are you learning on the job in the heat of the moment? How to you measure outcomes and ensure success? Blue Team Cyber Operations skill development depends on reusable, repeatable, and measurable scenarios that reflect complex networks to pit the blue team against a modern attacker. It isn’t enough to take a class and run through a lab. Attackers and Red Teams have dozens of options (including your network), and so does the Blue Team. On a Cyber Range can get you there, but it’s much more than a few virtual machines. It’s about achieving a real outcome: a trained operator, armed with tools, techniques, and practices that so they can get in the hunt. This presentation will introduce you to a modern range, survey best of breed tools and capabilities, and highlight how a range can support skill development for the Blue Team operator.
