What defines a security incident?

A security incident is defined as an event that compromises the integrity, confidentiality, or availability of information. This definition encompasses a wide scope of potential issues that can arise within an organization and highlights the fundamental aspects of information security.

When we talk about integrity, we're addressing the accuracy and trustworthiness of data; confidentiality refers to the measures in place to protect information from unauthorized access; and availability ensures that data and systems are accessible when needed. A situation that affects even one of these pillars can be deemed a security incident, as it poses a risk to the overall security posture of the organization.

The other options do not capture the completeness of what constitutes a security incident. While a minor breach of data or unauthorized access attempts are concerning, they do not necessarily involve a significant compromise of the broader aspects of information security. Predicting potential threats is part of risk management rather than direct implications of an actual incident. Therefore, understanding a security incident requires a holistic approach that aligns with the definition of compromising the key principles of information security.
