This indicates whether a particular log-reading job reads security logs or administrative audit records from its source, log or audit. This distinguishes a job feeding SmartEvent's security-incident correlation from one feeding its administrative or audit-trail reporting, which matters when only audit-related dashboards, not security incidents, seem to be missing recent data. For example, a job with data type audit going offline would specifically stop administrator-action tracking from updating, while security-event correlation from other log-type jobs continues unaffected.
