In Dec 2022, Yum Shoen Yih became Head of Special Projects at the Cyber Security Agency (CSA) of Singapore after 7 years being Director of Cyber Security Programme Centre (CSPC) where he was responsible for securing classified government networks and systems and to implement security programmes to enable a resilient nation and safer cyberspace. This also coincided with his retirement from Singapore Ministry of Defence (MINDEF) after nearly 50 years of defending the country. Much of his SAF (RSN) career was doing OpsTech integration to achieve more effective SAF warfighting capabilities, which contributed to his development of cybersecurity concepts to deal with sophisticated cyber-attacks. For the last 20 years, he focussed on securing Singapore cyberspace with special interest to secure non-government entities because they lack cybersecurity expertise and resources. Thus, he curated a costeffective solution using Singaporean security companies to implement a holistic and integrated solution (Asset Based Cyber Defence/ ABCD) to secure businesses/entities and our way of life on the Internet. In 2025, he was inducted to the Hall of Fame of The Cybersecurity Award for his contributions in securing Singapore’s cyberspace. He is frequently requested to speak at international and local conferences on cybersecurity.
