The present disclosure describes computer-implemented methods, computer program products, and computer systems, for role-based plants unattended premises occupancy monitoring, mapping, and events logging. One computer implemented method includes unlocking a mechanical door controllable by a computing device upon successfully validating login information input by an occupant, performing an occupancy footprint mapping (OFM) by periodically calculating the occupant's location using a triangulation process, determining an identity of the occupant based a received RFID signal, identifying a job role for the occupant based on the occupant's identity, identifying a normal OFM associated with the occupant's job role, calculating a deviation between the OFM and the normal OFM, sending a security event including the OFM to a Syslog server and an object linking, and sending an embedding for process control alarm to a human machine interface if the deviation exceeds a predetermined deviation tolerance threshold.
