The paper presents a novel paradigm of software-defined network that is significantly different from previous traditional networks and enables new opportunities in the architecture and implementation of security solutions. The analysis of network environments will compare traditional networks and software-defined networks and emphasize significant differences. A survey of the existing research includes vector attacks and troubleshooting using the capabilities of SDN with an emphasis on access control, detection, and prevention of attacks. This paper uses previous research and results to obtain information that will be used in improving critical system network protection and compares it with the existing conventional approach as well as implements it through a hybrid software-defined network.
