Also with the ever evolving threat landscape, most cloud platforms are always enhancing and updating their services to be able to detect / block new forms of attacks. The biggest security issue with public cloud is not the lack of functionality but how to implement and operate the different security services that the platform provides.

Within Microsoft Azure there are many different security services as part of the portfolio.

  • Azure Security Center – Threat detection service. Also works as an recommendation engine to check enviroment according to best-pratices. Uses data from the Microsoft Intelligent Security Graph to detect abornal traffic / activity and attacks. Works against IaaS and PaaS services. Also has an built-in integration with Qualys to provide in-guest software vulnerability scanning.
  • Azure Sentinel – SIEM/SOAR Service, built upon Log Analytics to provide analytics and hunting rules against data that is collected into Log Analytics. Also provides integrations with data sources and threat integillence services.
  • Microsoft Defender ATP – EDR Service. Collects data from endpoints and servers that are enabled with Azure Security Center. Collected information about process and network traffic.
