AI vs. Cybersecurity: Unpredictable Systems Break Models

AI's unpredictable and dynamic nature is breaking traditional cybersecurity models. This is because modern security programs were built on the assumption of predictable systems. What's interesting is that previous technology shifts, like the internet and cloud computing, also created new security problems. However, AI differs because it challenges this foundational assumption of predictability. Historically, security teams operated in environments where systems behaved deterministically. Applications executed the same way, and infrastructure changed slowly. Even cloud transformation allowed familiar security models to be applied. But AI changes these assumptions. Agentic systems make dynamic decisions, and large language models generate different outputs based on context. AI systems interact in ways developers can't always predict. The bottom line is that when systems stop behaving consistently, the traditional "keep bad things out" approach to cybersecurity starts to break down. Prevention still matters, but it's not enough when risk continuously evolves at runtime. This means cybersecurity leaders need to shift their focus to real-time runtime visibility.
