Gartner: DDoS defenses have been backsliding but starting a turnaround

Tim Greene | June 16, 2016
After a surge by attackers, DDoS defenders are battling back.

Many businesses have multiple ISPs, so they should do the math to see if it makes sense to use this option, he says. Some ISPs he mentions: AT&T, CenturyLink, Level 3 and Verizon.

Content-delivery networks can also help mitigate DDoS attacks, he says, by virtue of their architecture. CDNs distribute customer Web content around the world so it’s as close as possible to end users. That distribution makes it harder for attackers to find the right servers to hit and diffuses their capabilities.

This option isn’t for everyone, he says. It’s not as effective as the others and it doesn’t make sense unless a business needs a CDN anyway to boost its response time.

Web application firewalls can help mitigate those DDoS attacks that seek to disrupt use of Web applications. They can be deployed on premises with gear owned by the customer, but internet-hosted and cloud-based WAF services are emerging, Orans says. Cloud-based WAF is fastest growing for mobile devices that must be deployed quickly, he says.
