SIEM
SIEM (Security Information and Event Management) is a cybersecurity tool that collects, analyzes, and correlates security event data from various sources across an IT infrastructure. It provides real-time monitoring, threat detection, and incident response capabilities by aggregating logs and alerts from network devices, servers, applications, and security systems. SIEM systems help organizations comply with regulations, identify security incidents, and improve overall security posture through centralized visibility.
Developers should learn SIEM systems when working in security-focused roles, such as DevSecOps, cloud security, or application security, to monitor and protect applications and infrastructure from threats. It is essential for detecting anomalies, investigating security breaches, and ensuring compliance with standards like GDPR, HIPAA, or PCI-DSS in industries such as finance, healthcare, and e-commerce. Using SIEM helps in proactive threat hunting and automating responses to security events in complex environments.
