We have to connect one site to another using leased fiber ( theoretically it's a dark one ) in order to replace a radio link. All servers are in one site. Both location now have Gigabit networks.

Can you please tell me, beside VPN ( which would require some changing in configuration of our devices and application ) what else can be used in order to have a secure communication:

  • prevet acces to data transmitted via fiber,
  • prevent unauthorized access to our networks through this fiber.

I have searched over Internet and seems that there are some "encryptors" devices ( SafeNet for example ) but the price I have found are high.

Thank you

    Use quantum entanglement. Problem solved. – HopelessN00b Oct 28 '14 at 19:21
  • A VPN is definitely the correct way to do this. – gparent Oct 28 '14 at 19:43

    which would require some changing in configuration of our devices and application - What solution do you believe that you will find that doesn't require changing some configuration? What change specifically are you worried about? – Zoredache Oct 28 '14 at 19:46

I think you're defining VPN too narrowly. IPSec was invented exactly for this sort of situation. Almost all business-grade routers, any modern OS, and a variety of other devices can do IPSec. Take your pick.
