The field of modern networks and advanced technologies is witnessing rapid development, posing increasing challenges to cybersecurity, particularly with the proliferation of Software-Defined Networks (SDN) and Network Function Virtualization (NFV), as well as the growing reliance of organizations on cloud computing and critical digital services. Protecting these networks from cyberattacks has become an urgent necessity to ensure service continuity and information integrity. SDN and NFV are essential tools for enhancing network flexibility and efficiency, yet they also introduce new avenues for cyber threats. This makes cyber risk analysis in cloud networks a critical step in identifying vulnerabilities and implementing effective preventive measures. In this context, artificial intelligence (AI) plays a key role in detecting and preventing cyberattacks by analyzing patterns and predicting threats before they occur, thereby enhancing the technical teams’ ability to respond efficiently. These technologies are particularly vital in securing military and critical communication networks, where any breach or tampering could have serious implications for national security and critical operations. Moreover, integrating modern technologies with cybersecurity strategies contributes to building a secure and reliable communication environment, ensuring service continuity while minimizing risks, and enhancing the capability for immediate response to any potential threat or attack.
