Campaign planning would depend on what its purpose is. Tactical cyberwar planning would follow war planning in general, although it may be used beforehand to create opportunities for kinetic war to exploit. Strategic cyberwar planning should also follow from the goals that it is trying to achieve, e.g., regime change, a reduction in popular support for the government policies, to enhance the status and prestige of the attacker, etc.

What will be the role of Artificial Intelligence in cyberwar?

AI is likely to be used both by attackers and defenders. For attackers, AI could be used to find vulnerabilities to exploit and to war-game various attack plans to understand their effects. For defenders, AI could be used on a continuous basis to detect system anomalies that point to intrusions. If AI proves as effective as its proponents maintain, it is likely to further tilt the playing field away from talented amateurs and towards professional organisations.
