This week we've been talking a lot about security, and especially security for video applications. One challenge facing everyone -mobile, cloud, video -is Distributed Denial of Service (DDoS) attacks.

Three key points -

1. Attacks are getting bigger. We're now seeing volumetric attacks of up to 400 Gigabits per second.
2. DDoS attacks are getting more frequent -even daily.
3. The latest DDoS attacks are becoming more sophisticated and multi-vector. Not just one mechanism is being used, which makes them harder to defend against.

Worse of all is that DDoS is being used to cover-up other threats. While you're distracted fighting off a Denial-of-Service attack your content could be in the process of being stolen. With the right protection however, DDOS attacks can be squashed at the edge of the network, before any firewall or other device gets overwhelmed.

We recently caught up with Tom Bienkowski of Arbor Networks to hear what's going on in DDoS -both trends and mitigation techniques.

Arbor and Cisco have teamed together to develop an integrated solution that combines technologies from both companies to mitigate DDoS attacks at the edge of the network.
