What qualifies as a security incident?

A security incident is defined as any event that poses a threat to the confidentiality, integrity, or availability of information or information systems, and may require a coordinated response to mitigate any potential damage. The correct choice notes that a security incident includes any security event that necessitates the engagement of an incident response team.

This is significant because the formation and involvement of an incident response team indicate that the event is serious enough to warrant professional handling due to potential risks such as data breaches, cyber attacks, or unauthorized access. These types of incidents typically require specialized skills and knowledge to resolve and are treated as high priority within organizations.

The other options do not meet the criteria for a security incident. Routine maintenance tasks are standard procedures that are expected and do not typically pose a risk to security. Technical errors might occur, but not all technical errors signify a breach or a significant risk to security; they could simply be resolved through normal troubleshooting without involving an incident response approach. Minor disagreements within a team do not relate to security risks and do not warrant any form of incident response, as they pertain more to interpersonal dynamics rather than technical or security concerns.
