What is IPsec (Internet Protocol Security)? - TechTarget

WebMar 9, 2024 · IPsec is the short acronym for Internet Protocol Security. The “IP” stands for Internet Protocol, which is the main routing protocol used on the Internet for sending data to its destination using IP addresses. The “sec” stands for secure, as it provides encryption and authentication to the data transmission process, making it more secure. WebIPsec operates in one of two modes—transport or tunnel. When both ends of the tunnel are hosts, you can use either mode. When at least one of the endpoints of a tunnel is a security gateway, such as a Junos OS router or firewall, you must use tunnel mode. Juniper Networks devices always operate in tunnel mode for IPsec tunnels. WebJul 30, 2024 · IPSec uses two modes of operation; tunnel mode and transport mode.
