A piece in The Japan Times just pointed out a big change: AI is starting to break down the very basis of deterrence that we have relied on in cyberspace and other areas. For a long time, deterrence was all about being able to find out who’s responsible for attacks and then being able to threaten them with a counterattack. But with AI, even very small groups or single people can have access to disruptive capabilities which were previously only available to the big powers of the world.<\/p>

The piece hints that because of new AI tools, “almost anyone” can gain the power to coerce, thereby shaking to the foundations our ideas about security. This opening up of offensive power to everyone means that deterrence – which is based on the idea of punishing a retaliatory attack – will lose its grip when the attackers cannot easily be found, and when the cost of carrying out attacks is drastically lowered.<\/p>

It’s clear that deterrence is giving way to continuous defense. Rather than counting on the threat of retaliation, organizations have to really think about getting attacked and how they can reduce the damage when it happens.<\/p>

This is consistent with the general direction of the industry. AI is not only becoming a common weapon in cyberattacks but also a protective measure, resulting in a constantly changing “AI vs AI” scenario in cybersecurity. Those who are able to use AI defensively will be at a great advantage.<\/p>

A piece in The Japan Times just pointed out a big change: AI is starting to break down the very basis of deterrence that we have relied on in cyberspace and other areas. For a long time, deterrence was all about being able to find out who’s responsible for attacks and then being able to threaten them with a counterattack. But with AI, even very small groups or single people can have access to disruptive capabilities which were previously only available to the big powers of the world.The piece hints that because of new AI tools, “almost anyone” can gain the power to coerce, thereby shaking to the foundations our
