What does the term "security incident" encompass?

The term "security incident" broadly encompasses any attempted or actual unauthorized access, use, disclosure, modification, or destruction of information. This definition is comprehensive, covering a wide range of security issues that can compromise the integrity, confidentiality, and availability of data.

For instance, a security incident can include scenarios where an unauthorized user attempts to access sensitive information but is thwarted, as well as cases where data is successfully accessed and altered without permission. Recognizing the full spectrum of potential incidents is crucial for effective security measures and incident response strategies, as even attempted access can indicate vulnerabilities that need to be addressed.

The correct choice highlights the necessity for organizations to be vigilant not only about breaches that result in loss but also about attempts that may hint at existing weaknesses in their security posture.
