Risk = Impact (Severity of threat) X Likelihood (Probability of
the risk)

15. Cost vs. Control
15

16. » 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.

17. 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
