HONG KONG ISSUES CODE OF PRACTICE UNDER THE PROTECTION OF CRITICAL INFRASTRUCTURES (COMPUTER SYSTEMS) ORDINANCE

Summary from the TLDR InfoSec newsletter

Hong Kong's Office of the Commissioner of Critical Infrastructure issued a Code of Practice on January 1 that translated the Protection of Critical Infrastructures Ordinance into specific compliance requirements for critical infrastructure operators. The CoP establishes criteria for Critical Computer System designation (including SCADA and industrial control systems), defines material change notification triggers, mandates security audits and management plans, and clarifies incident reporting timelines—12 hours for serious incidents affecting service levels or causing data breaches, and 48 hours for other security incidents. Critical infrastructure operators should treat the CoP as the operative compliance benchmark and implement structured governance programs aligned with its technical baselines, security audit requirements, and incident response protocols to meet supervisory expectations.
