Description
To prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types); organizations must disable or restrict unused or unnecessary physical and logical ports/protocols on information systems.
Use of IKEv2 leverages denial of service (DoS) protections because of improved bandwidth management and leverages more secure encryption algorithms.
