What are the steps that can be taken to prevent flow-modification attacks on an SDN controller? The attack would look as follows(As seen by the image): enter image description here

Does OpenDaylight or any other controller have measures to prevent such an attack?

As with any network management or control scheme, you need to secure access to your SDN controller and between the controller and the hardware (authentication, dedicated VLAN, etc.). Of course, if your controller gets hijacked the attacker can do anything.

  • Are there any in-built security mechanisms in SDN controllers, such as OpenDayLight or Ryu to prevent this type of attack? To secure the controller being hijacked via an app through the northbound interface? I googled extensively but could not find a lot about flow-modification in SDN controllers. – Deepal Mar 23 at 13:53
