Yet IPSec’s operation can be broken down into five main steps:

  • “Interesting traffic” initiates the IPSec process. Traffic is deemed interesting when the IPSec security policy configured in the IPSec peers starts the IKE process.
  • IKE phase 1.
  • IKE phase 2.
  • Data transfer.
  • IPSec tunnel termination.
