In computing, Internet Protocol Security ( IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs). IPsec includes protocols for establishing mutual authentication ...
WebIPsec can also be used to provide authentication without encryption -- for example, to authenticate that data originated from a known sender. Encryption at the application or the transport layers of the Open Systems Interconnection (OSI) model can securely transmit data without using IPsec.
