The first step in creating your DDoS mitigation plan is deciding which technologies to employ. Most enterprises create a layered defense using complementary technologies. For example, pairing an overprovisioned infrastructure for small attacks with a third-party scrubber to mitigate larger and more persistent ones.

A remotely triggered black hole simply dumps all traffic from across the internet for a particular destination, using BGP to send it to a non-routable address space. Despite this major drawback, remotely triggered black holes are a commonly used DDoS mitigation technology.

Businesses's online assets are expanding at a dizzying rate, creating an ever larger and increasingly tempting attack surface for bad actors to target with distributed denial-of-service attacks.
