This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. In relation to the regional focus of the book, Asia, especially East Asia including Japan, China and South Korea, is an area of booming economies and also thriving communities of hackers. Managing the risk of cyber threat and attack is central to the book as many of the technological-based solutions are inadequate to deal with the ever-increasing volume of such attacks and all their many permutations. It becomes clear from the subsequent analyses that effective internal company-based risk management must be multidisciplinary including in-house legal departments, finance, sales, traders in the banking sector and underwriters in the insurance sector. Human resources input could also be invaluable in finding the disgruntled or revenge-bound employee or the employee with financial problems or a taste for luxury that their salary will not afford them.
