National resilience is an indicator of the reliability of the national security and defense system, mutual coherence of its components, which confirms their capabilities and resource potential to fulfill obligations and perform their main functions in conditions of instability of the internal and external environment. National resilience includes military capabilities and civil readiness, reflects society's ability to resist and quickly recover from the specified threats and their consequences.

Legal mechanisms include further improvement and harmonization of the regulatory framework, formation of relevant legal norms, state policy in the field of national security and international cooperation. Organizational measures are directed to expansion and further development of a single network of situational centers to increase the efficiency of information and analytical support for management decision-making.

The unity of the network of situational centers will contribute to increasing the reliability and effectiveness of condition monitoring of national security from more than 20 directions, in order to effectively coordinate the activities of state bodies. 374Volodymyr Pylypenko et al.
