Introduction to SIEM
SIEM(Security Information & Event Management)
SIEM (Security Information & Event Management) systems combine Security Information Management (SIM) and Security Event Management (SEM), to form a complete system for tracking, detecting, and responding to cyber threats. Through data collection, analysis, and response steps integrations; SIEM systems provide real-time insights that allow security teams to respond more swiftly and efficiently when threats emerge - SIEM systems have become essential tools in modern cybersecurity as they can handle large volumes of information while uncover threats traditional tools might overlook.
