Goal
Detects when multiple failed logins are seen from the same IP address, indicating a potential brute force attack is occurring.
Strategy
Monitoring of Windows event logs where @evt.id is 4625 and grouping by @network.client.ip.
Triage & Response
Verify if {{@network.client.ip}} is expected to be attempting to access the network. It is possible for this detection to be triggered by services and applications attempting to authenticate with recently-expired credentials.
