What does data compromise refer to?

Data compromise refers specifically to instances where data has been disclosed or modified without authorization. This can happen through various means such as hacking, insider threats, or accidental leaks. The essence of a data compromise is that the integrity and confidentiality of the data are breached, resulting in unauthorized individuals accessing or manipulating sensitive information.

The correct answer focuses on the most critical aspect of what constitutes a data compromise. When data is disclosed, it means that sensitive information is accessed by someone who should not have it, which can lead to serious repercussions for individuals or organizations. Additionally, if data is modified, the trustworthiness of that information is undermined, potentially causing misinformation and further security concerns.

The other options address different scenarios related to data but do not capture the essence of data compromise. Loss of access pertains to denial of service rather than unauthorized access. Unintentional data sharing relates to data leaks but does not emphasize the unauthorized modification aspect of a compromise. Loss of storage capacity is unrelated to access or integrity issues typical of a data compromise. Thus, the most accurate description in the context of data compromise is related to its unauthorized disclosure or alteration.
