This presentation addresses the escalating challenges in modern cybersecurity, where traditional Security Operations (SecOps) are overwhelmed by increasing threat actor activity , rising complexity , and the weaponization of generative AI by cybercriminals. It details Google's vision for transforming security from a reactive, alert-driven model to a proactive, threat-centric cyber defense posture leading to AI security, addressing both runtime protection for generative AI applications and the integrity of the underlying AI/ML supply chain. A comparison of historical application security failures and modern AI vulnerabilities. It introduces Google's Model Armor solution and the unique security challenges of the AI software supply chain. Ultimately, the presentation advocates for a holistic security strategy that combines robust runtime defenses with a secure supply chain to enable confident and responsible AI adoption.
