Security policies

Connection security involves the authentication of two computers before they begin communications and the securing of information sent between two computers. Windows Firewall with Advanced Security uses Internet Protocol security (IPsec) to achieve connection security by using key exchange, authentication, data integrity, and, optionally, data encryption.

NoteUnlike firewall rules, which operate unilaterally, connection security rules require that both communicating computers have a policy with connection security rules or another compatible IPsec policy.
