This new networking model is recent, but now it is a high-value target for attackers. As discussed before, we said that a single point of control is a huge threat for assets. SDN comes with a single point of control; that is why great power comes with great responsibility. If an attacker succeeds in compromising a SDN, they will control the entire network. Another attack vector is SDN applications; in the end, they are programs and, as such, any software malfunction or badly written code could lead to a system compromise. DDoS attacks and sniffing are also real threats to SDNs that can damage the entire network. The following illustration describes some attacks in the different model layers:
