In Azure Data Factory under the Settings options of "Networking", we have to disable the "Public Network Access", under the "Network access" option. If the public network access is "Enabled" then it is Open to Internet, which states that - "All Networks, including Internet can access Data Factory". And this is more threat of exposing the Data Factory to internet. For which we need a powershell/AZ CLI command which will help us to disable the 'Public Network Access".
