US: GTFS real-time - Secure Internet (ITS)

Description

This solution is used within the U.S.. It combines standards associated with US: GTFS real-time with those for I-I: Secure Internet (ITS). The US: GTFS real-time standards include upper-layer standards required to implement real-time, public, transit-related communications. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Includes Standards

Level	DocNum	FullName	Description
Mgmt	IETF RFC 3411	An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks	This standard (RFC) defines the basic architecture for SNMPv3 and includes the definition of information objects for managing the SNMP entity's architecture.
Mgmt	IETF RFC 3412	Message Processing and Dispatching for the Simple Network Management Protocol (SNMP)	This standard (RFC) contains a MIB that assists in managing the message processing and dispatching subsystem of an SNMP entity.
Mgmt	IETF RFC 3413	Simple Network Management Protocol (SNMP) Applications	This standard (RFC) includes MIBs that allow for the configuration and management of remote Targets, Notifications, and Proxys.
Mgmt	IETF RFC 3414	User-based Security Model (USM) for version 3 of the Simple Network Management Protocol (SNMPv3)	This standard (RFC) contains a MIB that assists in configuring and managing the user-based security model.
Mgmt	IETF RFC 3415	View-based Access Control Model (VACM) for the Simple Network Management Protocol (SNMP)	This standard (RFC) contains a MIB that supports the configuration and management of the View-based access control model of SNMP.
Mgmt	IETF RFC 3416	Version 2 of the Protocol Operations for the Simple Network Management Protocol (SNMP)	This standard (RFC) defines the message structure and protocol operations used by SNMPv3.
Mgmt	IETF RFC 3418	Management Information Base (MIB) for the Simple Network Management Protocol (SNMP)	This standard (RFC) defines the MIB to configure and manage an SNMP entity.
Mgmt	IETF RFC 4293	Management Information Base for the Internet Protocol (IP)	This standard (RFC) defines the MIB that manages an IP entity.
Security	IETF RFC 5280	Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile	This standard (RFC) defines how to use X.509 certificates for secure communications over the Internet.
Security	IETF RFC 8446	The Transport Layer Security (TLS) Protocol	This standard (RFC) specifies Version 1.3 of the Transport Layer Security (TLS) protocol. The TLS protocol provides communications security over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.
ITS Application Entity	GTFS Realtime	General Transit Feed Specification Realtime	This document defines a feed specification that allows public transportation agencies to provide real-time updates about their fleet to application developers. It is an extension to GTFS (General Transit Feed Specification), an open data format for public transportation schedules and associated geographic information. GTFS Realtime was designed around ease of implementation, good GTFS interoperability and a focus on passenger information.
Facilities	IETF RFC 7230	Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing	This standard (RFC) defines the main Application Layer protocol used for the world-wide web.
Facilities	ISO 21320-1	Information technology — Document Container File — Part 1: Core	ISO/IEC 21320-1 specifies the core requirements for 1) document container files, and 2) implementations that produce and/or consume document container files. It normatively references the Zip File Format Specification version 6.3.3 of PKWARE(R) Inc. Document container files are conforming Zip files as specified by that document.
Facilities	IETF RFC 4180	Common Format and MIME Type for Comma-Separated Values (CSV) Files	This standard (RFC) documents the format used for Comma-Separated Values (CSV) files and registers the associated MIME type "text/csv".
TransNet	IETF RFC 2460	Internet Protocol, Version 6 (IPv6) Specification	This standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng.
TransNet	IETF RFC 4291	IP Version 6 Addressing Architecture	This standard (RFC) defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses.
TransNet	IETF RFC 4443	Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification	This standard (RFC) defines the control messages to manage IPv6.
TransNet	IETF RFC 793	Transmission Control Protocol	This standard (RFC) defines the main connection-oriented Transport Layer protocol used on Internet-based networks.
Access		Internet Subnet Alternatives	A set of alternative standards that includes any Subnet Layer method of connecting to the Internet.

Readiness: High-Moderate

Readiness Description

One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
