Description
Lack of authentication enables anyone to gain access to the network or possibly a network element that provides the opportunity for intruders to compromise resources within the network infrastructure. By identifying and authenticating non-organizational users, their access to network resources can be restricted accordingly. Non-organizational users will be uniquely identified and authenticated for all accesses other than accesses explicitly identified and documented by the organization when related to the use of anonymous access. Authorization requires an individual account identifier that has been approved, assigned, and configured on an authentication server. Authentication of user identities is accomplished through the use of passwords, tokens, biometrics, or in the case of multifactor authentication, some combination thereof. This control applies to application layer gateways that provide content filtering and proxy services on network segments (e.g., DMZ) that allow access by non-organizational users. It focuses on authentication requests to the proxied application for access to destination resources and policy filtering decisions rather than administrator and management functions.
