The book focuses on applying the data-centric security (DCS) concept and leveraging the unique capabilities of software-defined networks (SDN) to improve the security and resilience of corporate and government information systems used to process critical information and implement business processes requiring special protection. As organisations increasingly rely on information technology, cyber threats to data and infrastructure can significantly affect their operations and adversely impact critical business processes. Appropriate authentication, authorisation, monitoring, and response measures must be implemented within the perimeter of the system to protect against adversaries. However, sophisticated attackers can compromise the perimeter defences and even remain in the system for a prolonged time without the owner being aware of these facts. Therefore, new security paradigms such as Zero Trust and DCS aimto provide defence under the assumption that the boundary protections will be breached.

From one perspective, the rapid development of communication and information networks, systems, and applications contributes to creating new and more effective forms of work organisation and process management. Advanced technological solutions enable government and commercial organisations to increasingly use cloud solutions to obtain on-demand availability of computing and data storage resources, accelerating the development and deployment of applications while improving their manageability and reducing maintenance effort. Using programmable networks reduces long-term costs, improves operational flexibility and transparency, optimises bandwidth and resource allocation, and enables the network to respond to application status and resource requirements. They are increasingly used in various applications on a microscale, such as in a system-on-a-chip and on the macroscale in wired and mobile systems. Advances in the next generation of wireless technologies allow for the implementation of highly interconnected cyber-physical systems, such as Internet of Things (IoT), providing an opportunity for timely and cost-efficient data collection and fusion.

However, as organisations increasingly rely on information technology, threats to the availability, integrity, and confidentiality of data and infrastructure can significantly affect their operations and impact the intended effects. One of the key threats we are seeing is the increasingly sophisticated, complex and growing cyber attacks. These attacks seriously threaten essential ICT systems that are often vital to reliable and safe operations and achieving organisational goals and objectives. Consequently, they can significantly damage critical business processes and the security and resilience of the entire organisation. Furthermore, privacy and data security remain issues that must be addressed to avoid obstacles in adopting new advanced technologies.
