Cost vs. Control

15

» The possibility of occurrence of a security event is inversely proportional to the expenditure justified for ISMS control. » Sensor Networks forms the base of a smart city.» Software patch management for sensor networks is a daunting task.» IDS/IPS as a first line of defense for sensor networks is challenging.

16

Conclusion: Cyber-attacks , Malware and Availability are the major threats for a smart city Applying controls to the network and communication technologies is the most cost intensive countermeasure strategy Smart energy is most vulnerable with most of the threats posing high risk to the assets
