How does IPsec work? IPsec connections include the following steps: Key exchange: Keys are necessary for encryption; a key is a string of random characters that can be used to "lock" (encrypt) and "unlock" (decrypt) messages. IPsec sets up keys with a key exchange between the connected ...
IPsec is a suite of protocols and services that provide security for IP networks. It ensures secure transmission of IP packets on the Internet.
PPTP –Point-to-Point Tunneling Protocolis an older VPN protocol some providers still use. It is fast but has known security vulnerabilities. L2TP/IPSec –Layer 2 Tunneling Protocolis often used with IPSec to provide encryption. It is less secure than other VPN protocols but is widely supported...

and replay protection. Because IPSec is integrated at the Internet layer (layer 3), it provides security for almost all protocols in the TCP/IP suite, and because IPSec is applied transparently to applications, there is no need to configure separate security for each application that uses TCP/...
Layer 2 Tunneling Protocol is a VPN protocol that does not provide any form of encryption, but it is commonly paired with IP security standard RFC 2401-2412, which defines how a VPN can connect securely across IP networks. The IPsec framework provides confidentiality, integrity and origin authent...
