Abstract

An attack is detected on a first IP address and a determination is made that the first IP address is associated with a primary digital certificate that is bound with multiple different domains. For each of these domains, a secondary certificate is accessed that is bound only to that domain and that secondary certificate is associated with a unique IP address such that each of the different domains has a unique IP address associated with its secondary certificate respectively. The attack is isolated to the domain the attack follows.
