I cannot get my news.
Like many news junkies, I use the Feedly RSS service to aggregate my news. But Feedly has been all but crippled in recent days as hackers have compromised the company’s network with repeated distributed denial-of-service (DDoS) attacks. I wonder how long I can hold out before I have to change how I get my news. I also am concerned as to how long Feedly will stay in business unless they repulse their attackers definitively in the near future.
Since most companies rely on their network to a greater or lesser degree, the threat of DDoS attacks is a real one for more than just firms that offer a customer-facing cloud service. Every business that uses a data center should worry about DDoS.
Recently Alcatel-Lucent (News - Alert) (ALU) issued an application note, “SDN Analytics for DDOS Mitigation: Solving Real World Enterprise Problems Today,” that as the title states, shows an effective way to help combat DDoS attacks: SDN analytics.
Ad context for those who may not be familiar, Software Defined Networks (SDN) is an industry initiative to bring virtualization to networking infrastructure. Just as virtualization has revolutionized the data center and delivered both cost benefits and added flexibility, SDN does much of the same for the network. Among its benefits, SDN can bring application fluency to enable better networking, and automation for automatic provisioning of networking infrastructure.
But, how can SDN help mitigate the risks of DDoS?
The answer lies in the fact that SDN delivers a continuous stream of measurement data that helps the network adjust in real-time. This is ideal for being used to quickly spot and adjust to DDoS attacks and mitigate the damage from them. With SDN, DDoS can be spotted and the networking infrastructure can adjust on-the-fly to combat such attacks.
“The key making this solution scale is the use of hybrid port OpenFlow,” noted the application note. “The solution uses an OPEN (News - Alert) SDN Controller to leverage the standard sFlow and OpenFlow capabilities of existing network hardware to provide a scalable, automated, cost effective solution that allows Enterprise networks to effectively mitigate flood attacks.”
Unfortunately, this solution might be too late for Feedly. But, hopefully other businesses can put SDN into practice for better DDoS mitigation.
