Which of the following is an example of a security incident?

A security incident is typically defined as an event that could compromise the integrity, confidentiality, or availability of an organization’s information or IT assets. Malware attacks directly fall within this definition, as they involve malicious software designed to disrupt, damage, or gain unauthorized access to computer systems.

In contrast, employee training sessions, software updates, and regular maintenance checks are proactive measures aimed at enhancing security and preventing issues. These activities are part of a strategy to mitigate potential risks but do not represent incidents themselves. Therefore, identifying malware attacks as a security incident highlights the importance of recognizing and responding to threats that can negatively impact IT security and organizational operations.
