What is SIEM?

Definition: SIEM combines Security Information Management (SIM) and Security Event Management
(SEM).

Purpose: Detect, analyze, and respond to security threats in real-time.

Key Benefit: Provides visibility into network activity to identify and respond to potential cyberattacks.

Evolution: Now uses AI for smarter, faster threat detection and incident response.

How SIEM Tools Work

Collects, aggregates, and analyzes real-time data from applications, devices, servers, and users.

Uses predetermined rules to define threats and generate alerts.

Goal: Detect and block attacks in real-time.
