Windows Security Event ID 4740 records the condition “A user account was locked out.” Consequently, a detection that counts EventCode 4740 events and aggregates them by user is specifically measuring repeated account-lockout activity. The appropriate detection is therefore Detect Excessive User Account Lockouts .
From a detection-engineering perspective, a useful analytic would establish a baseline or threshold and then aggregate by the affected account, for example conceptually using stats count by user. A high number of lockouts may indicate password spraying, credential-stuffing activity, an incorrectly configured service using stale credentials, or an automated process repeatedly authenticating with an invalid password. Context such as source workstation, account type, time window, and historical frequency would improve fidelity.
The distractors represent different telemetry classes. Excessive successful or failed logins normally involve authentication events such as 4624/4625 rather than 4740. Network-connection detections require network or endpoint connection telemetry, and AWS security scanning is unrelated to Windows account-lockout auditing.
The supplied material presents EventCode 4740 specifically in this detection-selection context on page 3.
