-
AI Threat to Critical Infrastructure: As operational technology (OT) becomes more connected, critical infrastructure like hospitals and power grids are increasingly targeted by cyberattacks, making artificial intelligence a both defensive necessity and risk factor.
-
Increased Ransomware Targeting: Ransomware groups and nation-state actors are focusing their efforts on the telecommunications and education sectors, which account for nearly half of global ransomware activity combined.
-
AI-Assisted Adversaries: Cybercriminals increasingly employ AI-assisted attacks, which are often designed for stealth rather than immediacy, allowing them to cause maximum impact when they eventually attack.
-
AI-Driven Network Security: Given the speed and scale of AI-assisted attacks, AI-driven defense measures are necessary to match the advanced tactics used by adversaries.
-
Security Challenges with Unmanaged Devices: Many critical infrastructure devices lack the capability to install traditional network security software, leaving them vulnerable and necessitating AI-driven network security for comprehensive monitoring.
-
Role of AI in Digital Infrastructure: The rise of digitalization in critical infrastructure has created a massive scale of interconnected networks, making manual monitoring impossible and highlighting the need for AI-driven solutions.
-
Examples of Cyber Incidents: Recent attacks, such as those on the U.S. water and wastewater sector, demonstrate the vulnerabilities of digital-physical infrastructure and the prolonged recovery times involved.
-
Building Digital Trust with AI: While deploying AI in critical infrastructure’s defense also brings risks, notably from agentic AI, AI remains crucial for bridging talent gaps, automating defense, and ensuring digital trust for ongoing modernization and service delivery.
-
Government Guidance on Agentic AI: Agencies like CISA emphasize the need for security controls to protect critical infrastructure from the risks associated with the deployment of agentic AI systems in operational contexts.
