The Cable Guy article for October: Portions of this column discuss a prerelease version of Windows Server 2008. Those details are subject to change.
Windows Vista and Windows Server 2008 (now in beta testing) both support Authenticated Internet Protocol (AuthIP), an enhanced version of the Internet Key Exchange (IKE) protocol. Both AuthIP and IKE are protocols used to determine keying material and negotiate security parameters for communications protected using Internet Protocol security (IPsec). AuthIP provides simplified IPsec policy configuration and maintenance in many configurations and offers additional flexibility for IPsec peer authentication. This article describes the protocol details of AuthIP and coexistence behaviors between IPsec peers that support either both AuthIP and IKE or only IKE.
