According to Arbor Networks’ latest Worldwide Infrastructure Security Report, the amount of Distributed Denial of Service (DDoS) attacks on data centers has been on the rise over the past year, increasing from under 50 percent in 2012 to a shocking 70 percent in 2013. Other alarming statistics include Data Center owners reporting that more than twice the number of DDoS attacks had surpassed the total data center bandwidth compared to 2012 with ten percent reporting more than 100 attacks per month.
Not only did the number of DDoS attacks grow, but the size of the attack as well - most notably with the Spamhaus reflection attack. This attack made people aware of the vulnerability of their datacenters, with attacks of over 100Gbps becoming increasingly common. Datacenters tend to rely on firewalls and IDS/IPS systems to take on these attacks through closing ports or filtering specific types of traffic. While this method can work in some instances, it also stops useful applications from working.
A different method that ensures availability for legitimate users and useful applications, while blocking bad traffic, is through DDoS mitigation technology. Juniper Networks offers a solution called Junos DDoS Secure, which is specifically designed to provide comprehensive DDoS protection for the data center. Junos DDoS Secure uses its unique CHARM algorithm to learn which IP addresses can be trusted, and then responds intelligently and in real time by dropping suspect or noncompliant packets when the optimum performance from critical resources starts to degrade.
