"SIEM" refers to the fusion of the functions of security information management (SIM), that is, the process of collecting, monitoring and analyzing data from automatically generated computer logs (reports), and security event management (SEM), the process of centralizing computer log data from several sources (systems, endpoints, applications and services) to improve the detection of security incidents and the management of these events through a formalized response process.
The evolution of SIEM by adding case automation has spawned a new class of systems that SIEM has essentially outgrown. They called them SOAR. Depending on what underlies this system, it may have different names: Security Operations, Analytics and Reporting (SOAR) or Security Orchestration, and Automated Response. SOAR is a special tool for summarizing information about security threats, which are provided from various sources, and further analyzing this data.
The advantage of SOAR is the complete automation of information security management processes: starting from prioritization and ending with responses to incidents. Unlike the analysis of logs provided by SIEM, SOAR solutions incorporate a whole set of different technologies that support the activity of service centers and monitoring services. The use of SOAR allows for the integration of information coming from different sources about threats to the security system. This is achieved through three main modules.
