Today’s trend of increased use of virtual and cloud networks has proven to offer new cost effective opportunities for organization and data centers, but on the other hand, has opened organizations to vulnerability from sophisticated outside attackers.
The need for backup, business continuity and data transport between multiple data center sites has grown. In addition, today’s enterprise networks have extended from on-premise to remote cloud virtual networks, thus forming high bandwidth optical transport network to connect between the remote sites over increasing distances . Therefore the data transport networks today are exposed to security holes previously not encountered. This situation has made traditional premise security devices insufficient for today’s needs.
Transport Protection Options for remote data centers and disaster recovery connectivity as well as for cloud and virtual networks, fiber optic infrastructure has been widely used. With WDM solutions, multiple data rates can be multiplexed together and be transported across the network with ultra low latency. The fiber infrastructure also offers huge capacity, with up to 96 wavelengths of 100G transported over a single fiber.
Until recently, fiber optic cable was considered more secure than other transport mediums, and virtually immune to data hacking. However, recent studies proved that even fiber can be hacked by using different methods and relatively simple tools. This raised a need for transport security measures over fiber networks as well. Just owning your own dark fiber infrastructure is no longer guarantee for data security.
In order to provide secured fiber optic link, a combination of physical premise protection, secured management protocols, with encryption method and with optical power level monitoring should be used. The combined method provides the network administrator the set of tools that help to prevent, detect, isolate and counter any potential or occurring data hacking attempt.
