Why Cyber Security :
In this world of interconnected systems and computers the boundary where the digital world begins and ends is often blurred.
a. Is your phone a computer ?
b. How about Amazon Alexa or Google Home and the interconnected lights or security locks at your house ?
c. How about the wireless electricity meter in your house ?
d. How about the new Tesla Roadster parked in your garage ?
All the above are examples of interconnected computer systems which collect, retain and transmit information (data).
Similar to the way houses are protected via fences, alarms , doors and safe designs – computer systems (hardware and software) can be protected from any malicious activities . The art and science of protecting these systems (irrespective of whether they are interconnected or not) is called Computer security or Cyber Security.
