The Journal of Communication and Network Security (JCNS) is a peer-reviewed open-access journal dedicated to addressing the evolving security challenges at the intersection of advanced communication technologies and modern network infrastructures. In an era defined by the rapid deployment of 5G/6G networks, the Internet of Things (IoT), satellite communications, and cloud-edge systems, securing these complex, interconnected environments has become paramount. JCNS serves as a vital platform for publishing high-quality research works that advances the theory, design, and implementation of robust security solutions for current and next-generation communication and network systems.
