Abstract

In one embodiment, a distributed denial of service attack on a network is identified. In response to the distributed denial of service attack, a script to request a short term certificate is executed. The short term certificate is generated by a certificate server and received either directly or indirectly from the certificate server. An instruction to redirect traffic using the short term certificate and private key is sent to a distributed denial of service attack protection service that is operable to filter or otherwise mitigate malicious traffic involved in the distributed denial of service attack.
