Network Security Division of NIRS Gwangju initiated wiretapping and illegal filming detection activities on March 12 to prevent information leakage caused by possible RF eavesdropping and secret recording devices.

Audio and video signal transmissions were analyzed at critical places, resulting in that there was none of RF eavesdropping and secret recording devices installed.
NIRS Gwangju will regularly conduct these types of detection activities to be thoroughly prepared against potential information leakage incidents, expecting to ensure the "clean NIRS Gwangju" environment with zero eavesdropping and secret recording.
