Say “identity management” and what usually comes to mind is LDAP directories, strong authentication and Single Sign-On (SSO) systems. These technologies are used for access to Windows networks, e-mail and other internal applications. Generally, network identity is associated with IP and MAC addresses, VLAN tags and subnets. It also plays a role in security in areas like device authentication, VPNs and IPSEC. ESG believes that the historical differences and separation between application- and network-layer identity no longer make sense. This white paper describes why and proposes a new model for identity-aware networking.
