I think we should have international, legal community studies of cybersecurity and necessary laws, and countries should be encouraged to adopt these laws through the United Nations just like they adopt laws to prevent the abuse of children and protect human rights.
There needs to be a multidimensional, multilayered and multi-azimuth defense. That is, defense has to look in all directions. When you're talking about cybersecurity, you're talking about being able to protect your points. It's not directed against a country, but to secure your points of access or specific end points or network access. It's not as though you're arming yourself against a specific threat - you're simply undertaking all aspects of protection.
