What is considered a 'security breach'?

A 'security breach' specifically refers to an incident in which unauthorized individuals gain access to confidential information, which can include personal data, financial records, or any sensitive corporate information. This unauthorized access can lead to significant consequences for individuals and organizations, such as identity theft, financial loss, and damage to reputation.

In the context of security and data protection, a breach typically implies that security measures have been compromised in such a way that the integrity, confidentiality, or availability of information is at risk. This makes option B the most accurate definition of a security breach compared to the other options, which do not capture the essence of unauthorized access to confidential information.

While property damage and interactions with law enforcement may involve security concerns, they do not specifically define a breach of security protocols or systems. Similarly, a minor violation of security policy does not rise to the level of a significant breach since it might not necessarily involve unauthorized access to sensitive information. Thus, the focus on unauthorized access in the correct answer clearly delineates what constitutes a security breach in the broader context of data and information security.
