Information support and corporate security technologies within the integrated ecosystem of economic and legal governance of enterprises and IT clusters

The article substantiates the ecosystem approach to information security and enterprise security as a fundamental condition for effective economic and legal management in the context of digitalization. It is emphasized that modern enterprises operate in an environment of high dynamics of digital transformations, growth in data volumes, intensification of cyber threats and strengthening of regulatory requirements, which determines the need for a comprehensive approach to the protection of information resources. It is substantiated that information security should be considered not as a purely technical function, but as a strategic component of the management system, which affects the stability of business processes, financial stability, reputation and trust of stakeholders. The role of modern information technologies, in particular DLP, SIEM, VPN, IDS/IPS, in ensuring the CIA triad (confidentiality, integrity, availability), as well as in timely incident detection, access control, event monitoring and prevention of critical data leaks, is determined. It is shown that the effectiveness of technological solutions is significantly increased if they are coordinated with internal regulations, access control policies and legal liability mechanisms within the framework of economic and legal management. An integrated model of information flow protection based on the IDEF0 methodology has been developed, which combines technical means with organizational policies, control procedures and legal norms, ensuring the systematicity and manageability of security processes. A mathematical tool for assessing the probability of information security and an economic criterion for minimizing costs have been proposed, which allows justifying the feasibility of investments in security taking into account risks and potential losses. It has been proven that the integration of security technologies into the overall management strategy contributes to compliance control, reducing economic and legal risks and increasing the competitiveness of business in the digital environment.
