It's imperative we defend against the cyber criminals
The worldwide cyber attack at the weekend is a shocking example of the ruthlessness of those people who can cripple so many computer systems and create havoc on a wide scale.
So far the main corporations and institutions in Northern Ireland seem to have been unscathed, but perhaps it is only with the return to work today that we will understand the full nature of the damage.
This has been a strong warning to everyone that they must take every step to protect themselves from such attacks.
Certainly, our local companies and business and other organisations must defend themselves urgently in the face of such major threats.
