Understanding SIEM and SOAR
All cloud providers offer native services for security monitoring, such as Azure Security Center, AWS Security Hub, and Security Command Center in Google Cloud. However, companies are going multi-cloud using Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) from different providers. Enterprises want an integrated view of their security in all these solutions. If an enterprise is truly multi-cloud, it will need an integrated security solution with SIEM and SOAR.
Next, the enterprise needs a unit that is able to handle and analyze all the data coming from SIEM and SOAR systems and trigger the appropriate actions in case of security events. Most enterprises have a Security Operations Center (SOC) to take care of this. In this section, we will explain what the differences are between SIEM and SOAR, why an enterprise needs these systems in multi-cloud, and what the role of the SOC is.
