What does IPsec stand for?

IPsec stands for Internet Protocol security. It is a suite of protocols that helps secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet within a communication session. IPsec operates at the network layer of the Internet Protocol Suite, providing protection for data as it moves across the network. It ensures confidentiality, integrity, and authentication of the data, making it a critical component in securing Virtual Private Networks (VPNs) and establishing secure direct connections over the internet. Understanding IPsec and its application is essential for anyone working with network security, as it enables secure communication in various contexts, from internet browsing to corporate intranets.
