IT Interview Questions:How do I deploy IPSec for a large number of computers? What is IPSec?
IPSec is an encryption protocol designed to work at the IP level. As you might know, Kerberos is the primary Windows authentication protocol. Kerberos and IPSec differ in that Kerberos provides user-to-service authentication. IPSec on the other hand is used to encrypt
and authenticate communications between computers on the network. It is a low-level protocol that has absolutely nothing to do with securing access to data or services on a server. IPSec's main goals are to encrypt communications across an IP-based network (such as the Internet and most private networks) and to guarantee that a transmission has not been tampered with en route.
One simple benefit of IPSec is that it's built into Windows. That means you don't have to buy any additional software and you don't have to worry about compatibility issues when implementing IPSec policies. You also don't have to do anything to deploy IPSec onto the server or client PCs -- you just create an appropriate group policy.
