Definition
The Cyber Trust Mark is a government-backed certification that operators of critical infrastructure (power, telecom, finance, etc.) must obtain, and Singapore has now made it mandatory to specifically cover AI security practices. It works like a safety label — proof that the organization's AI systems have met a baseline government-verified security standard.
Why it matters
This is one of the first times a government has turned a voluntary AI security label into a binding legal requirement for critical infrastructure, signalling where other regulators are likely to head next.
