Abstract
The present invention provides a method, apparatus, and computer instructions for warning of a presence of a person in a zone having an inadequate security clearance. Movement of the person in the zone is detected. A message is broadcast to selected data processing systems associated with the zone, wherein the data processing systems initiate actions to protect data in the selected data processing systems.

A data processing system for warning of a presence of a person in a zone having an inadequate security clearance, the data processing system comprising:
- a bus system;
- a memory connected to the bus system, wherein the memory includes a set of instructions;
- a processing unit connected to the bus system, wherein the processing unit executes the instructions to:
- receive a message by a selected data processing system within a plurality of data processing systems located within the zone, wherein the message indicates the presence of the person entering the zone;
- initiate security actions to protect data displayed on the selected data processing system, wherein initiating the security actions further comprises:
- identifying a security level of each window in a plurality of windows displayed at the selected data processing system;
- selecting at least one window in the plurality of windows on which to perform the security actions to form selected windows, wherein a window in the plurality of windows is selected to form the selected windows if a security level of the window is greater than the security level associated with the person;
- and performing the security actions to protect the data displayed on the selected windows while data displayed in other windows in the plurality of windows remain displayed, wherein the security actions are performed depending on a confidentiality level of the data being displayed at the data processing system;
- and
- monitor for additional messages indicating a presence of an unauthorized person in the zone, wherein the cessation of receiving the messages indicates that the security actions no longer need to be taken.
