Prior to leaving for an extended vacation, Joe uses his mobile phone to take a picture of his family in the house living room. Joe posts the picture on a popular
social media site together with the message: “Heading to our two weeks vacation to Italy.” Upon returning home, Joe discovers that the house was burglarized.
Which of the following is the MOST likely reason the house was burglarized if nobody knew Joe’s home address?

A.
Joe has enabled the device access control feature on his mobile phone.

B.
Joe’s home address can be easily found using the TRACEROUTE command.

C.
The picture uploaded to the social media site was geo-tagged by the mobile phone.

D.
The message posted on the social media site informs everyone the house will be empty.

Explanation:
Geo-tagging is the process of embedding the GPS coordinates in image files and images taken using a smartphone or a digital camera. The geotagged information
accompanying the image allows anyone to discover the precise location where the image was taken.

Incorrect Answers:
A: Device access control is the process of controlling which users have access to a device. This is accomplished through the use of screen locks that require the
user to enter a password or pin after a period of inactivity.
B: TRACEROUTE is a network diagnostic tool used to trace the path from a client to a host machine. It cannot be used to determine the physical location of a
house.
D: The message posted on the social media site does inform everyone the house will be empty but it does not disclose the location of the hose. An attacker would
still need to determine the location of the house.
