UK firms using Indian IT and back-office facilities are being urged to upgrade their security in the wake of a suspected terrorist attack on Bangalore, the country’s technology hub and a popular offshore destination for Western firms. Indian IT trade group Nasscom said that while the country’s IT sector has implemented many security measures, the incident shows a need to review and upgrade protection. UK firms with Indian sites should ensure they have security provisions such as metal detectors, CCTV, security guards and strict access policies, advised Peter Ryan of analyst Datamonitor.
