Enhanced SDN security using firewall in a distributed scenario

Software Defined Network (SDN) attract much attendance from research and industrial area; reason behind is the open interface, user controlled management and lower operating cost for data/flow handling rules that implements on software module rather than embedding in hardware with greatly improve performance. Network with the high security demanding higher in this generation. New service and products provide advanced technology and flexible architecture but changing in network landscape can introduce new security issues. SDN simplifies hardware, software and management of network device but faces many forms of attack. SDN or TNA (Traditional Network Architecture) has same uses firewall to manage legacy network traffic. This paper introduce firewall for SDN infrastructure to secure network attached device from suspicious and malicious traffic regarding to attack and access control to enhancing SDN security by distributing system.
