IPSec Review IPSec is a framework of open standards for encrypting TCP/IP traffic within networking environments. IPSec works by encrypting the information contained in IP datagrams through encapsulating to provide data integrity, data confidentiality, data origin authentication, and replay protection. IPSec uses cryptography to provide authentication, data integrity, and data confidentiality services. Authentication deals with verifying the identity of the computer sending the data, or the identity of the computer receiving the data. IPSec can use digital certificates, the Kerberos v5 authentication protocol, or pre-shared keys as an authentication method. Read More
