    Set Up HTTPS Log Forwarding to Microsoft Sentinel

    Forward HTTPS logs from Cortex Data Lake to Microsoft Sentinel.
    1. Log in to your Microsoft Azure account, and create a log analytics workspace in your Sentinel.
    2. Create and deploy an agent web app to decompress data from Cortex Data Lake.
      1. Install Visual Studio Code version 1.64.1 or a later version.
      2. Install the Azure Tools and Azure App Service extensions in Visual Studio Code.
      3. Obtain the agent web application’s code from GitHub.
        git clone https://github.com/PaloAltoNetworks/cdl-decompress-proxy-sentinel-ingest.git
        Download and extract the ZIP folder if you did not install Git.
        https://github.com/PaloAltoNetworks/cdl-decompress-proxy-sentinel-ingest/archive/refs/heads/master.zip
      4. Open the
        cdl-decompress-proxy-sentinel-ingest
         folder in Visual Studio Code.
        If you downloaded and extracted the ZIP folder in 2.c, ensure to navigate to the final folder in the extract called
        cdl-decompress-proxy-sentinel-ingest-master
         when you open the folder in Visual Studio Code.
      5. Click the Azure icon and sign in to Azure.
