Important Security Updates to the ArcGIS Platform

January, 2019

Esri have recently announced upcoming improvements to ArcGIS Online in order to maintain the highest industry standards for data integrity and network security. Starting on 16 April 2019, ArcGIS Online will only accept TLS 1.2 connections for ArcGIS Online services. Some software, like ArcGIS Pro, are already TLS 1.2 enabled. Other Esri software, such as ArcGIS Desktop, uses TLS 1.0—this software requires a patch or configuration change to support TLS 1.2 connections. Esri is releasing patches and instructions to update existing software to support these connections.

What is TLS?
TLS or  “Transport Layer Security” is a widely deployed network security protocol. It provides privacy and data integrity between communicating applications over a network. You use TLS whenever accessing ArcGIS Online services, such as basemaps, geoprocessing services, and the Living Atlas, from ArcGIS Desktop, ArcGIS Enterprise, and other applications.

Who is affected?
Users of most ArcGIS software or custom solutions using Esri technology may be affected by this planned update to TLS protocol v1.2.

What do I need to do to prepare for this change?
Go to the Esri TLS Support page for more information and specific actions you may need to take in advance of this update; or book a consultation with a Technical Support Specialist who can guide you through the update and the appropriate patches for your environment.

How to test or validate the TLS 1.2 Connection to ArcGIS Online?

After you have updated your software or operating system to support TLS 1.2 connections, you can verify the changes by testing the connections to sample ArcGIS Online services.
