Description

Introduction of SIEM for Security Monitoring

Security Information and Event Management (SIEM) is a critical component in modern cybersecurity operations, enabling organizations to collect, analyze, and respond to security threats in real time. This course introduces the fundamentals of SIEM, covering key concepts, use cases, and best practices for implementing an effective security monitoring strategy. Participants will gain insights into log management, threat detection, correlation rules, and compliance requirements.

Prerequisites

• Basic knowledge of networking and cybersecurity concepts.
• Familiarity with security logs and event monitoring is helpful but not mandatory.
• Understanding of common security threats and incident response practices.
