The rapid growth of the Internet of Things (IoT) has brought new security challenges, making it increasingly important to ensure the security and privacy of connected devices. Network Softwarization and Security Automation theme focusing on addressing this issue and secure deployment of software network. Our team is dedicated to exploring the key research topics in the field of Network Softwarization and Security Automation, with a focus on the use of Network Slicing and Mobile Edge Computing (MEC) for IoT security, offering security as a service through Network Softwarization, Zero Touch security management, and security service migration. We are also investigating the integration of attack detection and mitigation into Network Softwarization, providing real-time monitoring and rapid response to security threats.
