Why is SIEM important?
Combining security information management (SIM) and security event management (SEM), security information and event management (SIEM) offers real-time monitoring and analysis of events as well as tracking and logging of security data for compliance or auditing purposes.
Put simply, SIEM is a security solution that helps organizations recognize potential security threats and vulnerabilities before they have a chance to disrupt business operations. It surfaces user behaviour anomalies and uses artificial intelligence to automate many of the manual processes associated with threat detection and incident response and has become a staple in modern-day security operation centres (SOCs) for security and compliance management use cases.
Over the years, SIEM has matured to become more than the log management tools that preceded it. Today, SIEM offers advanced user and entity behaviour analytics (UEBA) thanks to the power of AI and machine learning. It is a highly efficient data orchestration system for managing ever-evolving threats as well as regulatory compliance and reporting.
How does SIEM work?
At the most basic level, all SIEM solutions perform some level of data aggregation, consolidation and sorting functions in order to identify threats and adhere to data compliance requirements. While some solutions vary in capability, most offer the same core set of functionality:
