“The latest challenge on the security front isn’t necessarily an exotic new threat vector: it’s the attackers themselves. They’re organized, well-resourced and patient. And there’s no silver technology bullet to effectively combat them.”
This is a very important point, and one that I have seen at other security conferences for the last 5 years or so. However, attacks are possible because there is a lack of confidentiality and integrity of the data held within the systems under attack. So the system becomes the week point.
