3. Discuss openflow protocol (Q3 image) and please discuss the details of the protocol such as any security concerns or vulnerabilities. (75words)
Answer preview
Open Flow protocol enables servers to give instructions to network switches to send different data packets. Switches that use the Open Flow protocol can easily separate data paths from their original control path hence managing and directing traffic among switches and routers. Open Flow protocol is vulnerable to attack where maliciously configured switches can be connected to a controller, which requires no authentications (Alshanqiti et al., 2019). An attacker can use this chance to cause denial-of-service making the controller unable to have access.
