Identification and monitoring of event sources

Critical
High
Normal
Low

The organization shall determine what security events it monitors and in what ways.

Security events should be monitored from a variety of sources to identify important potential incidents that require a response. Information can be obtained e.g. directly from the management system, external partners, or logs generated by the organization’s equipment.

Examples of security incidents that can be monitored include:

  1. Slow server performance
  2. Recurring login errors
  3. Unknown login attempts
  4. Abnormal network traffic
  5. Out of storage
  6. Changes in code projects
  7. Configuration changes in the firewall
  8. Access changes to critical systems / servers / databases
  9. Large database downloads
  10. Unauthorized software installations on endpoint devices
  11. Traffic from IP addresses known to be malicious
