Theoretical Aspects of Data Confidentiality in Infocommunication Networks

Data confidentiality in information and communication networks is a hot topic in the modern digital world. With the development of infocommunications and global information infrastructure, the volumes of transmitted and processed information have acquired an unpredictable scale. In this context, ensuring data privacy becomes a vital concern. A growing number of cyber threats, including hacking, phishing, data theft and privacy breaches, pose risks to the security and privacy of information transmitted over networks. Known cases of leakage of confidential data, such as personal information, commercial and state secrets, and medical records, demonstrate the need for effective means and methods of protection. In addition, public awareness regarding data privacy and confidentiality is growing. Users are becoming more aware and aware of the risks associated with storing and transmitting their personal data online. This is driving demands for organizations and companies to ensure strong privacy protections for their customers. In recent years, there has been a significant increase in the amount of digital data stored and transmitted through information and communication networks, thanks to new technologies such as the Internet of Things, cloud computing, social networks, e-commerce and other digital technologies that have become an integral part of our daily lives. This creates a need to reliably protect these large volumes of data from unauthorized access and malicious activity. The number of cyber threats is constantly growing, and attackers are constantly developing new methods of attack and cybercrime, which jeopardizes data confidentiality. From hacking attacks, phishing, malware, to identity theft and business disclosure, digital threats are becoming more complex and dangerous. Ensuring data confidentiality is becoming a critical need to avoid financial losses, privacy breaches and other negative consequences.
