These changes could impact the use of web services from ArcGIS Online or ArcGIS Enterprise/Server.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Next February Esri will be dropping support for TLS 1.1 and earlier. It will only support TLS 1.2 and newer. What is TLS you may ask? TLS stands for Transport Layer Security. It provides data privacy and integrity between applications communicating over a network including the internet. TLS has replaced the older SSL as a more effective and efficient way to securely communicate across a network. TLS does this by having stronger message authentication, key-material generation and other encryption algorithms. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>To learn more about TLS and how it works, check out these links:<o:p></o:p></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l1 level1 lfo3'><a href="https://www.networkworld.com/article/2303073/lan-wan/lan-wan-what-is-transport-layer-security-protocol.html">https://www.networkworld.com/article/2303073/lan-wan/lan-wan-what-is-transport-layer-security-protocol.html</a> <o:p></o:p></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l1 level1 lfo3'><a href="https://en.wikipedia.org/wiki/Transport_Layer_Security">https://en.wikipedia.org/wiki/Transport_Layer_Security</a> <o:p></o:p></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l1 level1 lfo3'><a href="https://youtu.be/VzWqnT5dErI">https://youtu.be/VzWqnT5dErI</a> <o:p></o:p></li></ul><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you are currently using ArcGIS Online services such as basemaps, data layers, web maps and geoprocessing services, then you have been using TLS to access those items.

You will need to install patches that allow ArcGIS to use the newer version of TLS. Esri is working on those patches right now. They should be released soon.
