Preventative tools like anti-virus and IDS, have not kept pace. Not by a long shot. This is a problem, because if we are not going to make any progress at all in defending against cyber attacks we will need both automation and artificial intelligence to help win the fight. For far too long, the key strategy in defending networks has been prevention, or not allowing bad things to happen in the first place. This strategy involves defending every single ingress and egress point and protecting against all threats to these points at all times. This strategy is far too complicated for most companies to ever get right. It involves addressing every possible vulnerability while the attacker only needs to find the single problem that was missed. Factor in a company's third and even fourth party vendors, cloud and mobile technologies and the complexity of implementing this defense immediately goes well beyond the capabilities of today's already over-stressed security teams. Security and IT teams operate with limited budgets and staffing and will likely continue to do so for some time as competing business priorities and the talent shortage continue with no end in sight. A relatively new approach to scaling information security defense involves replacing people with computers capable
