National Cyber Security Agency (NACSA)

The National Cyber Security Agency, known by its acronym NACSA, is the Malaysian federal agency designated as the national lead body for cyber security matters. Established in February 2017 and originally placed under the National Security Council, NACSA was later realigned under the Ministry of Digital. Its mandate covers the coordination of cyber security policy, the protection of Critical National Information Infrastructure (CNII), cyber crisis management, and the development of national capability. The agency has emerged as the principal Malaysian government actor on the cyber-security implications of artificial intelligence.

Mandate and structure

NACSA is responsible for developing and implementing national-level cyber security policies and strategies, protecting CNII, undertaking strategic measures to counter cyber threats, leading cyber security awareness and capacity-building programmes, formulating the strategic approach to cyber crime, advising agencies on cyber risk management, optimising shared resources across the public sector, and fostering regional and global cyber security partnerships.

The agency operates from Cyberjaya and works closely with related bodies including CyberSecurity Malaysia (the operational arm under the same ministry), the Malaysian Communications and Multimedia Commission (MCMC), the Royal Malaysia Police's commercial crime investigation department, and Bank Negara Malaysia for the financial sector. NACSA also represents Malaysia in ASEAN cyber forums and in bilateral cyber dialogues with partners including Singapore, Japan, the United Kingdom, Australia, and the United States.

Cyber Security Act 2024

The Cyber Security Act 2024, which came into force in 2024, gave NACSA statutory powers for the first time. Prior to the Act, NACSA operated under administrative authority. The Act establishes a formal regime for the designation of National Critical Information Infrastructure sectors, mandates incident reporting, empowers NACSA to direct audits and risk assessments, and creates licensing obligations for managed cyber security service providers operating in Malaysia. The Act applies to eleven CNII sectors including banking and finance, transportation, energy, water, health services, government, defence and national security, emergency services, food and agriculture, trade and industry, and information and communications.

Cyber Security Strategy 2025–2030

NACSA is finalising Malaysia's next national Cyber Security Strategy, covering the period 2025 to 2030. The strategy, which succeeds the Malaysia Cyber Security Strategy 2020–2024, explicitly incorporates emerging technologies including artificial intelligence, generative AI, and the cyber-security threats they enable. Public statements from the Ministry of Digital have confirmed that the strategy will address AI-enabled phishing, deepfake fraud, autonomous offensive cyber tools, and the security of AI supply chains used by Malaysian government systems.

AI security committee

In parallel with the strategy refresh, the Ministry of Digital has announced the formation of a national AI security committee under NACSA's coordination. The committee draws members from across the public sector, academia, and industry, with the remit of assessing AI technology against national security and ethical standards. Its work is intended to complement the broader Malaysia AI Governance Framework being developed by MDEC and the Ministry of Digital, and to ensure that AI systems used on CNII meet appropriate assurance levels.

Operational programmes

NACSA runs several recurring national exercises. The X-Maya cyber drill series tests CNII operators against simulated attacks across multiple sectors. The agency also coordinates the Malaysia Cyber Defence Operations Centre (MyCDOC) and contributes to the ASEAN Computer Emergency Response Team network. National cyber security awareness campaigns under the CyberSAFE programme, run by CyberSecurity Malaysia in coordination with NACSA, are extended to schools, universities, and small and medium enterprises across the country.
