What does the ProcessBlocked event type signify?

The ProcessBlocked event type signifies that a process creation was prevented by the sensor. This means that the CrowdStrike Falcon platform has identified a potentially malicious or unwanted process attempt and effectively stopped it from executing on the endpoint. This proactive measure helps protect systems from threats such as malware or unauthorized applications that could compromise security.

By blocking the process, the sensor acts as a critical defense layer, preventing potential damage before it can occur. This capability is essential in maintaining security and protecting sensitive data from being accessed or manipulated by harmful entities.

The other event types do not pertain to the blocking of a process. For example, terminating a process does not prevent it from being created, nor does logging out of the system or moving a file to quarantine directly involve blocking process creation. Therefore, the designation of the ProcessBlocked event is distinctly linked to the action of preventing a process from running, highlighting the system’s defensive capabilities.
