Abstract
Software-Defined Networking (SDN) has become popular in academics and industry, as it allows network administrators to control network services through abstraction of lower level network functionality. SDN provides improved programmability for network operators dealing with infrastructures with potentially thousands of switches. Unfortunately, SDN’s centralized network management makes it an attractive target for malicious users. In order to fully harness the power of SDN and offer a high degree of flexibility and openness in network operations, security and dependability must be ensured. To accomplish this, the first step is to protect the switches in SDN because they are vulnerable yet significant network components for reliable endto-end communications. This paper presents a defense method to address denial-of-service attacks on switches. The proposed method reliably prevents the overflow of the flow table in the switches by monitoring the usage of flow rules in the data plane. Without changing the current switch design, our method mitigates the seriousness of attacks on the switches.
