Enhancing Network Security by using SDN Algorithm in Cloud Computing

Key Points

Network topology poisoning attacks compromise the security of SDN implementations, leading to significant vulnerabilities.
The analysis indicates that all major SDN controllers, including Floodlight and Open Daylight, face risks from these attacks.
These attacks can lead to severe outcomes such as authorized data theft and man-in-the-middle scenarios.
Effective intervention requires understanding how SDN's operational differences from legacy networks influence vulnerabilities.

Abstract

Software Defined Networking (SDN) gives controllers and their applications the unmatched capacity to have thorough association detectable quality and versatile association programmability, thus enabling new developments in network shows and applications. One of the key benefits of SDN is its consistently assembled control plane, which provides the entire association with recognisable quality and is what different SDN applications rely on. We provide additional attack routes that are novel for the composition and unique to SDN, which seriously undermine this basis. Our new assaults are essentially the same as parodying attacks in legacy associations (such as an ARP hurting attack), but with significant differences in how current SDN operates significantly differently from legacy associations. The association geology data, a key building component for focus SDN sections and topography cautious SDN applications, can be successfully damaged by the productive attacks. The upper-layer OpenFlow controller organisations and applications may be completely duped by the harmed organisation detectable quality, leading to authorised taking, organisation rejection, or man-in-the-middle assaults. Our analysis demonstrates that every major SDN controller in use today— including Floodlight, Open Daylight, Beacon, and POX—is vulnerable because they depend on Network Topology Poisoning Attacks.
