Internet Protocol Security (IPsec) is a widely used network layer security control for protecting communications. IPsec is a framework of open standards for ensuring private communications over Internet Protocol (IP) networks. IPsec configuration is usually performed using the Internet Key Exchange (IKE) protocol. This publication provides practical guidance to organizations on implementing security services based on IPsec so that they can mitigate the risks associated with transmitting sensitive information across networks. The document focuses on how IPsec provides network layer security services and how organizations can implement IPsec and IKE to provide security under different circumstances. It also describes alternatives to IPsec and discusses under what circumstances each alternative may be appropriate.
