Life today is impacted by the cyber sphere in many ways, whether through emails, social media, video conferencing, data transmission, cloud storage, digital finance, or internet searches. Cyber risks and cyber security breaches abound – a global information technology (IT) disruption due to a cyber attack can bring the entire business world to a standstill; scams, hacking, and phishing cause serious losses. In the face of these risks and threats, heightened vigilance, acute awareness, and strong cyber security systems are crucial in protecting all sectors of society. This book delves into Malaysia’s legislative response to increasing digital threats. It provides a clear understanding of the newly enforced Cyber Security Act 2024 (CSA 2024), analyses cyber security governance, and considers the protection of national critical information infrastructures in the cyber security ecosystem. Various frameworks and best practices to manage cyber security incidents are studied. The book further reviews the licensing of cyber security service providers pursuant to the CSA 2024, giving a clear appreciation of how the regulations operate to enhance consumer protection, promote industry standards, and bolster Malaysia’s cyber security ecosystem. This book will be valuable to legal professionals, IT security practitioners, compliance officers, business owners, and students in navigating the complexities of cyber security law.
