WebJan 10, 2024 · According to the SDN structure, we constructed two attack methods [6,7], which achieve illegal access by tampering with flow rules and controlling flow.There are other direct attack scenarios, such as DDos: (i) As shown in Figure 3, the attacker tampers with the flow rule in OpenFlow Switch2, which allows malicious host a to access host c … Webwhich introduces vulnerabilities in the network making the flow rules untrustworthy. Access to data store can only be trusted if the security problems inherent in software-defined networks are resolved. In this paper, we propose an enhanced SOLID - FLOW to improve flow rules database integrity inside the SDN controller.
