"While there is currently no suggestion that systems within NI have been targeted, we remain conscious that we must act to ensure the integrity of cyber networks and take appropriate action to reduce the threat posed by cyber criminals."
An investigation's underway to find the hackers behind the cyber attack which crippled telephone and computer systems around the world.
It hit organisations in at least 99 countries.
The software used is said to be well known in the cyber security community.
