Science Ministry issues cybersecurity rules for AI used in critical infrastructure
Published · Updated
What happened
The Ministry of Science and ICT announced new regulations on 2026-09-25 requiring stronger cybersecurity controls for AI systems used in critical infrastructure, including periodic security audits and alignment with international standards.
Why it matters
The announcement creates a new compliance obligation for infrastructure operators, AI vendors, and auditors. It can change procurement, deployment timelines, liability exposure, and certification requirements for AI systems in regulated sectors over the next several days and weeks.
On 2026-09-25, the Ministry of Science and ICT released regulations that impose cybersecurity requirements on AI systems deployed in critical infrastructure. The rules require regular security audits and compliance with international standards, adding a concrete compliance layer for operators and vendors working in sectors such as energy, transport, communications, and public services. The immediate policy question is how quickly regulators enforce the rules and how operators sequence upgrades without disrupting essential services.
