+====== External Network Connection ======
+[[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
+===== Discussion =====
+An External Network Connection establishes a communication path between a system or environment under organizational control and a network outside the applicable control boundary.
+The term identifies the connection rather than the external network, the communication protocol, or a service reached through the connection.
+An organization governs an External Network Connection through applicable authorization, configuration, security, monitoring, and recording controls. A [[public:99_annexes:annex-b-terms-and-definitions:c:connected_environment|Connected Environment]] contains one or more authorized External Network Connections.
+===== Definition =====
+//a communication path between a system or environment within an organizational control boundary and a network outside that boundary//
+===== Source =====
+Adapted from the National Institute of Standards and Technology (NIST) definition of **external network**:
+[[https://csrc.nist.gov/glossary/term/external_network|NIST Computer Security Resource Center, “external network”]]
+===== Note =====
+The word **external** refers to the applicable organizational control boundary. It does not depend upon geographic location, ownership of the physical infrastructure, or use of the public Internet.
+An External Network Connection does not imply unrestricted access. Authorization and security controls determine the permitted endpoints, protocols, traffic, direction, duration, and purpose of the connection.
+An External Network Connection provides a communication path. An [[public:99_annexes:annex-b-terms-and-definitions:e:external_service|External Service]] provides functionality through or beyond the applicable control boundary.
+===== Example =====
+A DIDO-TE Connected Environment uses an authorized HTTPS connection to retrieve a software dependency from a repository outside the environment’s control boundary. The HTTPS communication path constitutes an External Network Connection.
