This log data provides the following information:

  • Security ID
  • Account Name
  • Account Domain
  • Logon ID
  • Task Name
  • Task Content

Why does event ID 4699 need to be monitored?

  • This should be monitored particularly on critical computers and devices, as malware uses schedules tasks to stay in the system after a reboot.
  • Scheduled tasks created by malware can be found in the Task Scheduler Library root node. Deletion of these tasks is a sign of malicious activity.
  • Critical tasks should never be deleted, so the Task Name field of this event must be monitored.
