Built as a native SDN application, Radware's DefenseFlow provides DDoS protection services and equips network operators with the following key advantages when adding DDoS protection into their infrastructure:
Attack detection is always performed out of path; during attack period only suspicious traffic is diverted through the mitigation device
DefensePro mitigation devices can be placed in any location, DefenseFlow diverts the traffic to the nearest mitigation device
Against all type of network DDoS attacks
In addition to the many advantages associated with moving to an SDN-based network, SDN-based DDoS detection enables more accurate and fast detection of DDoS attack than traditional network statistics methods.
One of the key requirements for security operations is for the security control system to be flexible enough to integrate within any environment and enable integration of different systems, network elements and applications. Some of these may already exist in the environment and others may be new. On the other hand, this requirement, when interpreted in a trivial manner, comes in contrast to maintaining a simple system which enables low engagement from operatives and high levels of automation.
DefenseFlow aims to tackle this conflict by being flexible enough to be deployed within any environment while keeping things simple to operate and abstracting many of the underlying complexities.
Legacy DDoS protection services that make use of scrubbing centers are costly because they need hardware detectors in every network location, BGP for traffic diversion, and GRE tunnels to forward the traffic to its designated network object. With SDN, a DDoS protection solution turns into a software application that adds intelligence to the network. There is no need for additional hardware, BGP or GRE operations, which is a great cost reduction opportunity for operators.
