In this edition of Between Two Nerds Tom Uren and The Grugq discuss the UK’s National Cyber Force’s recently published “Responsible Cyber Power in Practice” document. The Grugq thinks he’s been plagiarised, while Tom wonders whether the NCF’s “doctrine of cognitive effects” highlights the limits of cyber operations. It’s a good document and will be influential in shaping how people discuss offensive operations (those that disrupt, degrade, destroy etc).
