SDN is a modern model that has attracted many researchers in the networks since its inception. Since this model was mainly based on separating the control level and the data level which set within the same equipment in the old networks. With the suggestion of the feature of separating control from data transmission and the possibility of programming and adding features as needed in a flexible manner, the SDN architecture has a promising future in the world of networks. Despite the many advantages offered by SDN networks, we cannot ignore the security problem associated with SDN since its inception, which has attracted many researchers to work hard to fill these security gaps and reach a secure infrastructure for SDN networks. So, this research will be divided into parts that include the basic properties of the SDN network and its general structure, and the most important problems and attacks that may affect the structure of network and a review of previous research in this field. The best attempts made to find appropriate security solutions for SDN networks will be discussed. Also, the research will mention the most important attempts to design an integrated security design for SDN, and the future needs to reach a completely secure SDN network. |
