Dear Patrick,

I will recommend you to go through the Internet of Things (IoT). As they said:

"By 2020, More Than 25% of Cyberattacks Will Involve IoT Devices".

There are too many challenges facing IoT technology, you can initiate your research on these challenges.

Good luck (:

Privacy Preserving Identification/Authentication...

Threat analysis and dynamic protection strategies

Cost of damage estimation and adapted protection reinforcement

Many research/survey indicates that attacks are easier due to poor awareness about the basic security mechanisms among the network users. Hence, we should do the needful to provide training to the untrained/unaware people; which makes their surfing more safe over network.

Please Recommend our answer, Thanks:
