What is a security incident?

A security incident is defined as any event that compromises the integrity, confidentiality, or availability of information systems or data. This includes situations where unauthorized access occurs, data breaches happen, or systems are disrupted in a way that may expose sensitive information. Understanding this definition is crucial, as it captures the essence of threats that organizations must address to maintain a secure environment.

The option indicating a routine audit of security policies does not qualify as a security incident, as audits are proactive measures aimed at identifying and mitigating potential risks rather than events that compromise security. Similarly, scheduled maintenance of IT systems is a planned activity that helps ensure the optimal functioning of systems but does not represent an incident that jeopardizes security. Finally, enhancing the security posture of an organization is a positive outcome but does not describe an incident that threatens security. Thus, the correct identification of a security incident is vital for an organization to effectively respond to and mitigate risks associated with information security.
