Amid criticism over the delay in implementing Internet separation in the public healthcare sector — which would have prevented the recent SingHealth cyber attack — doctors and other employees told TODAY their routine work has been significantly disrupted after they have had to delink their computers from the Web starting last Friday (July 20).

Dr Bilveer Singh, who is an adjunct senior fellow at the Centre of Excellence for National Security at the S Rajaratnam School of International Studies, criticised the selective implementation of the Internet separation policy.

“If you have a policy, carry it out through the length and breadth. No use talking after the fact and say ‘it should have been’,” he said. “I think it is a no brainer issue… there have been attacks for the last 10 years already. (This is) nothing new.”
