security event (security incident)

Part of the Security management glossary:

A security event is a change in the everyday operations of a network or information technology service, indicating that a security policy may have been violated or a security safeguard may have failed.

Next Steps

The first indication of an event may come from a software-defined alert or by end users notifying a help desk that network services have slowed down. In some organizations, the term security event is synonymous with security incident. In other organizations, events are so common that they are handled automatically by high-end security information and event management (SIEM) vendor products and only those events that require an IT administrator to take action are classified as “incidents.”
