Abstract
Techniques are described to provide efficient protection for a virtual private network. In one example, a method is provided that includes obtaining a packet at a first network entity; determining that the packet is a packet type of an authentication type; determining whether authentication content for the packet matches known good criteria for the packet type of the authentication type; based on determining that the authentication content for the packet does not match the known good criteria, performing at least one of dropping the packet and generating an alarm; and based on determining that the authentication content for the packet does match the known good criteria, processing the packet at the first network entity or forwarding the packet toward a second network entity.
