In a general context, an event is something that happens or takes place, particularly something of importance. In computing and IT, an event often refers to an action or occurrence recognized by software that may be handled by the system or by user code. Events can include user inputs, system signals, or messages from other programs. In terms of cybersecurity, an event can be any observable occurrence in a system or network, including potential security incidents. Event management is a key part of system monitoring, and cybersecurity event logs are critical for incident response and forensic analysis. It is just a change to a system or data, it is not positive or negative, just an observable change.
