As a consequence of the proliferation of social technologies and the internet use in general, huge collections of data have been created, coming from possible different sources.


1::Botnets
1::Denial of Service
3::Identity Theft

This is not the correct answer. Botnets are network of infected computers that can be used for illegal (e.g. cyber-criminal) activities without their owner’s knowledge. While they are major cyber-threat, they are not related with Big Data. The correct answer among those provided is Identity Theft: the act of stealing someone’s identity information so as to be able to impersonate him/her. It is considered as an emerging attack since the increased discovery of information due to big data facilitates identity theft by malicious attackers. 

For more information, see the ENISA Threat Landscape 2015 Report, available here:

which discusses a number of emerging threats related with Big Data such as the possibility for attackers to better deploy malware, based on information gathered with Big Data (see p. 77-80).

 

This answer is not the correct one. Denial of Service is an attack in which a resource in a network (e.g. a website) is made unavailable for the user. While a Denial of Service is a serious cyber-threat, it is not related with big data. The correct answer among those provided is Identity theft: the act of stealing someone’s identity information so as to be able to impersonate him/her. It is considered as an emerging attack since the increased discovery of information due to big data facilitates identity theft by malicious attackers.

This concentration is called Big Data, and can be analysed with novel techniques for several purposes (e.g. in order to identify trends). However, Big Data can also open the door to cyberattacks and privacy issues.

Which of the following options is considered as an increased threat for general users due to big data?
