Singapore's national cyber security strategy has 4 pillars: 1) Protect critical infrastructure through assessments, information sharing, and security by design. 2) Combat cybercrime through education, law enforcement capabilities, and partnerships. 3) Develop a professional cybersecurity workforce and support startups to extend Singapore's advantage. 4) Forge international cooperation to counter cyber threats through ASEAN initiatives and host exchanges on cyber norms. The strategy aims to secure essential services, respond to threats, and establish Singapore as a trusted hub through a whole-of-nation approach.
