My book - Offensive Cyber Operations - is now back in stock in both the UK and US!
If you're interested in a practical approach for how countries can employ cyber-attacks for national security needs, check it out! I cover both a broad perspective on what makes an Offensive Cyber Operation tick (and succeed) and how different countries apply them uniquely.
In particular, I have four chapters dedicated to the United States, Russia, China, and Iran - each with their own strengths and weaknesses in using cyber ops.
