How does DSAC Annex B define "adverse impact"?

The definition of "adverse impact" in DSAC Annex B specifically refers to negative effects on data security that can result in the loss, damage, or compromise of information. This understanding is critical because it emphasizes the seriousness of potential risks in data management and security.

Identifying adverse impacts is essential for organizations to accurately assess vulnerabilities and implement appropriate countermeasures. For instance, if an organization does not recognize negative effects as adverse impacts, it may overlook significant risks that could lead to data breaches or loss of sensitive information, ultimately impacting operational integrity and trustworthiness.

The other choices do not align with this definition. Positive changes enhancing security, irrelevant consequences, or minor manageable risks fail to capture the gravity and significance that "adverse impact" represents in the context of data security and the protective measures organizations need to consider. Thus, the correct choice reflects a critical understanding of the threats and challenges that can affect an organization’s information security posture.
