The book explains the modern foundations of auditing work in an easily understandable way. For the first time systematically organized for practical application, it introduces systems of security intelligence, cognitive security, and swarm intelligence. Additionally, the edited volume provides guidance for auditors on handling new topics such as standard data protection models, security audits in industrial production, and IoT environments, as well as managing reports of economic crime and compliance violations in annual financial audits. This enables auditors to address these topics as systematic examinations, tests, and audits.
