Increasingly, companies large and small are leveraging the advantages of sharing resources across data centers, partially the result of an explosion in use of virtualization technology. This makes data center connect (DCC) security an even more important business consideration as traffic grows and more enterprise-critical data is passed between data centers.
Until recently, the gold standard for DCC security was encrypting data at rest, then sending it across a fiber optic cable and decrypting on the receiving end. This presented several challenges, however, from encryption key management to processing power, data latency and complexity.
Optical fiber isn’t the armored car it once was believed to be, either, Alcatel-Lucent (News 
- Alert) said in a recent white paper, Alcatel Lucent Delivering Comprehensive Enterprise DCC Security. It notes that a knowledgeable intruder who has access to the optical fiber can now purchase a device to eavesdrop for less than $1,000. Detection is hard to spot because the eavesdropping technology relies on bending the optical fiber until just enough light is leaked to capture the data without drawing attention from the sending or receiving data centers...
