Definition

Security Information and Event Management (SIEM) is a comprehensive solution that aggregates, analyzes, and manages security data from across an organization’s IT infrastructure. It provides real-time monitoring and analysis of security alerts generated by applications and network hardware, enabling organizations to detect, respond to, and mitigate security threats effectively. SIEM systems are crucial for compliance reporting and incident management, offering a centralized view of security events and logs.

Secure Settings Example

# Example SIEM configuration for secure log management
log_management:
  retention_period: 365 # Retain logs for one year
  encryption: true # Enable encryption for log data
  access_control:
    - role: admin
      permissions: read, write, delete
    - role: analyst
      permissions: read
  alerting:
    enabled: true
    thresholds:
      - event_type: failed_login
        threshold: 5
        time_window: 10m

Insecure Settings Example

# Example of insecure SIEM configuration
log_management:
  retention_period: 30 # Short retention period may not meet compliance
  encryption: false # Logs are stored in plaintext
  access_control:
    - role: *
      permissions: read, write, delete # Overly permissive access
  alerting:
    enabled: false # No alerting configured
