Cyber security and data management are among the biggest issues facing business and other organisations today. The law faces huge challenges to keep up with the rapid development of technology which provides opportunities for the misuse of computers for commercial gain or other reasons. This new work covers the vast spectrum of law, both civil and criminal, as it applies to data control, data management and cyber issues.
