Encrypting data so deep in the network has a few benefits:
First, it works on a wide variety of internet traffic types: including Ethernet, Fibre Channel, OTN, SONET, and SDH, which is a limitation with protocol-specific encryption.
Second, it is transparent and takes place at wire-speed. In other words, the encryption process does not slow down the signal, nor does it modify the data in any way.
Third, by encrypting traffic just before it enters the fiber, it can work on data generated by or delivered to any application or device: important in the cloud and app-driven BYOD era.
Encryption at the optical layer during transport provides a strong and effective safeguard, offering an additional level of protection to enable rigorous end-to-end network security. The best approach is to take a holistic security view and adopt a solution that will safeguard the network from end to end, protecting data on-premise as well as in-flight. When choosing a security partner and solution for 2016, enterprises must cover the three-point checklist of server security, at-rest data encryption and in-flight data encryption.
