Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.
Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems  or  
weaknesses that prevent malicious attacks.
To answer this question, think of a time when you experienced any one of these. For example, personally, I was once an unfortunate victim of a general malicious attack that took advantage of a weakness in my anti-virus software. After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer.  This was a malicious attack.
However, sometimes people can be specifically targeted to steal their data or monitor their activities.

The correct answer is  geo fencing.
<h3>
what is geo fencing?</h3>
A geofence is a fictitious geographic boundary that can be entered or exited by a mobile device or RFID tag. Geofencing is a location-based service in which an app or other software programme uses radio frequency identification (RFID), Wi-Fi, GPS, or cellular data to trigger a targeted marketing action (such as a text, email, social media advertisement, or app notification).
There are three ways to use this technology to target customers: geotargeting, geofencing, and beaconing. You can track a consumer's location using GPS, Bluetooth, and beacons.
