Explanation:
Connection Security Rules
Connection security rules are a special type of rule that deal with authenticated and encrypted traffic. You can use connection security rules to manage how communication occurs between different hosts on the network. You use the New Connection Security Rule Wizard, to create connection security rules. Connections can be authenticated using the Kerberos V5 protocol requiring a domain computer and user account or a domain computer account. If you select advanced properties, connections can be authenticated using NTLMv2, computer certificates from a particular certificate authority (CA) or using a pre-shared key.

Connection Security Rules and IPSec policies
The relationship between connection security rules and IPSec policies is similar to the relationship between AppLocker and Software Restriction Policies. Both sets of rules do similar things, but the ones that you use depend on the operating systems used by the client computers in your organization. All editions of Windows 7 and Windows Vista support connection security rules, but Windows XP does not.
