These days in the media it is not uncommon to hear that organisations and companies have suffered from cyber-attacks.


1::Ethical hacking
1::Trolling
3::Insider Threat

This is not the correct answer. Ethical Hacking is actually a positive practice and an ethical hacker is a professional who helps organisations improve their cyber defences (e.g. via trying to get unauthorized access into protected systems for assessing security).

The correct answer is Insider Threat. While it is common to think that cyber-attacks come from external sources, often attacks come from the inside. The insider threat – for example an employee - might obtain access to the computer systems or networks of an organisation, and then conduct harmful or criminal activities against the organisation. However a significant amount of insider threats stem from unintentional user errors/mistakes.

For more information about the insider threat and the current level of risk this has you can consult the ENISA Threat Landscape Report, and in particular the section 3.8, available here: https://www.enisa.europa.eu/publications/etl2015

 

This is not the correct answer. In the Internet Jargon a troll is a person that disseminates information, for example on online forum or Social Network Websites, to upset people or for causing disruption of an online conversation. The correct answer is Insider Threat. While it is common to think that cyber-attacks come from external sources, often attacks come from the inside. The insider threat – for example an employee - might obtain access to the computer systems or networks of an organisation, and then conduct harmful or criminal activities against the organisation.

The popular image is that these attacks are carried out by so-called malicious hackers that are external to an organisation. However several observations show that many of these attacks are carried out by organisation employees/officers or former employees.

What is the common name which is given to this latter type of threat?
