Top Highlights

• Governments have long had to protect their most sensitive systems against cyberattacks – often mounted by governments in other countries.
• Their approaches to defending their most critical systems are thus rooted in both critical necessity and practical experience. Those approaches are typically quite different from cybersecurity practices in the private sector.
• ut with increasing political realisation that protecting often commercially-held critical infrastructure and services is today just as important as protecting military and diplomatic secrets, many governments are, in principle, now open to sharing their knowledge.
• Since it sits at the heart of how spies protect themselves from other spies, perhaps this is not surprising.
• Commercial organizations will need to push their government partners to share information about how the latter achieve strong cybersecurity for their most sensitive systems, and they will need to devote time to learning and assimilating unfamiliar material.
