The Bangalore Chamber of Industry and Commerce(BCIC) and the National Association of Software and Services Companies have termed the terrorist attack on IISc as ‘‘a wake up call to Bangalore’’.In a release, BCIC President Anant R Koppar, however, said that the attack would not dislodge people’s confidence on Bangalore.‘‘The attack has woken up Bangalore, which is considered one of the peaceful cities in the country. It was the responsibility of every individual, corporate and society to tighten up vigilance,’’ he said.‘‘We can fight terrorism only through stringent security measures at sensitive locations and by creating greater awareness among people, especially those in the technology sector. It has become extremely important that companies invest in monitoring individuals who work directly or indirectly in organisations and invest in intelligence system in their premises,’’ he added.NASSCOM President Kiran Karnik, while expressing shock over the incident, said that IT companies had tight security in place. ‘‘But we will work with the government on what additional steps we need to take to further tighten security,’’ he said.At IISc, an uneasy calm prevailed, only those connected with the institute were allowed in. Even courier delivery boys were stopped at the gates and asked to come the next day.
