3 Ways to Defeat DDoS Attacks

In 2012, a number of DDoS attacks hit Bank of America, JPMorgan Chase, Wells Fargo, U.S. Bank and PNC Bank. These attacks have since spread across most industries from government agencies to local schools and are showing an almost yearly evolution, with the most recent focus being the Internet of Things (IoT).

In 2016, compromised cameras, printers, DVRs and other IoT appliances were used in a large attack on Dyn that took down major websites including Amazon, Twitter, Netflix, Etsy and Spotify.

Inside Distributed Denial-of-Service Threats

Although these large attacks dominate the headlines, they’re not what most enterprises will deal with day to day. The most common attacks are in the range of 20 to 30 Gbps or less, while larger attacks have been reported at 1.2 tbps.

Creating DDoS Defense

Security technology is becoming more sophisticated, but so are hackers, which means attacks can be much more difficult to mitigate now than in the past. Enterprises must be knowledgeable and prepared with mitigation techniques as the attacks continue to evolve.

DDoS mitigation comes in three models:

Scrubbing Centers

The most common DDoS mitigation option for enterprises is to buy access to a scrubbing center service. During an attack, traffic is redirected to the security provider’s network, where the bad traffic is “scrubbed out” and only good traffic is returned to the customer. This option is good for multi-ISP environments and can be used to counter both volumetric and application-based attacks. For added protection, some providers can actually place a device in your data center, but this is not as cost-effective as the cloud-based option.

ISP- Clean Pipes Approach

With the rise of DDoS attacks, many ISPs have started their own scrubbing centers internally, and for a premium will monitor and mitigate attacks on their customers’ websites. In this scenario, ISPs operate as a one-stop-shop for bandwidth, hosting and DDoS mitigation. But some ISPs are more experienced at this than others, so customers must be sure to thoroughly test and research the quality of the service offered by their ISPs.

Content Delivery Network Approach

The distributed nature of content delivery networks (CDNs) means that websites live globally on multiple servers versus one origin server, making them difficult to take down. Large CDNs may have over 100,000 servers distributing or caching web content all over the world. However, CDN-based mitigation is really only a good option for enterprises that require core CDN functionality, as porting content to a CDN can be a time-intensive project.
