We could expect increased security in places like malls, restaurants, and college/high school sports events. Any event where crowds of people are gathered will experience an all-new type of crowd control. Increased airport-like security, with scanners and strict control of all entrances and exits, would be aimed at establishing good crowd control and minimizing any chance of terrorist attacks.
An increase in cyber security
We are also likely to see an increase in cyber security, following the major data breaches like Equifax and the earlier Yahoo and Target breaches. In the Equifax case, the privacy of millions of customers was violated.
This shed light on the need for protection of privacy for consumers whose data is collected by companies. Cyber attacks are likely to continue to increase and better security is needed if consumers are to have the privacy they desire.
Any firms who are up to date on the latest technology who are at the forefront of contributing to security in public places and at large events will be in great demand. Those who contribute to cyber and credit card security are also likely to experience a boom.
