Death by a Thousand Paper Cuts
Denial of service attacks against the DNS have continued to grow in scope, volume and sophistication. A recent type of denial of service attack targets the DNS application itself, sending attack packets to consume the CPU and other resources within the server.

This mini-white paper describes the exclusive Secure64 Overload Defense which blocks PRSDs and is available in the Secure64® DNS Cache server.
