  • Microsoft Sentinel Repositories to push CI/CD changes to Sentinel

    With the latest announcement (november 8th, 2021) on Repository support in Microsoft Sentinel, we now have a supported workflow to enable Continoud Deployment integration from Azure DevOps or GitHub: https://techcommunity.microsoft.com/t5/microsoft-sentinel-blog/enable-continuous-deployment-natively-with-microsoft-sentinel/ba-p/2929413

    Out of the box the following content types are supported

    • Analytic rules
    • Automation rules
    • Hunting queries
    • Parsers
    • Playbooks
    • Workbooks

  • Use LogStash to copy SQL table with audit logs data to Microsoft Sentinel

    The goal of this experiment was to get a LogStash instance running in Docker to copy on-premise SQL Server data to Sentinel. If your application is still emitting data only to a SQL table and no other sources are available, this is a trick to get data into Sentinel until a permanent solution has been created.

    This is a first experiment, so no production ready code:

     docker run --rm -it -p5044:5044 --env xpack.monitoring.enabled=false -v /mnt/c/Users/MyUserName/pipeline/:/usr/share/logstash/pipeline/ -d docker.elastic.co/logstash/logstash:7.10.0 sh -c "logstash-plugin install microsoft-logstash-output-azure-loganalytics ; /usr/local/bin/docker-entrypoint"

  • API Management DTAP lessons learned

  • Troubleshooting IIS Client Certificate issues

    IIS has the option to require client certificates, but setting this up requires all settings to be set correctly.
