What Do You Know About IPsec?

Whenever a communication session starts using IPsec protocol, this protocol encrypts all the IP data packets of the session. This protocol also makes sure that a mutual authentication process takes place between the agents before the initiation of the communication and it also make arrangements for the encryption keys to be used in the communication session. IPsec has its encryption being occurred within the kernel with multithreading, which it makes its protocol faster than regular OpenVPN. IPsec has two varieties that it is commonly used by VPN apps: L2TP/IPSec and IKEv2/IPsec.
