What can result from a security breach?

The selection of unauthorized access or disclosure of sensitive information as the correct answer highlights a key consequence of a security breach. When a security incident occurs, it often leads to individuals gaining access to information that they should not have, whether it be due to exploitations of vulnerabilities or weaknesses in security controls. This unauthorized access can result in severe implications, including the exposure of personal data, intellectual property, or proprietary business information. Such breaches can compromise the confidentiality, integrity, and availability of information, severely impacting an organization’s reputation, financial status, and compliance with legal obligations.

The other options do not accurately reflect consequences of a security breach. Improved system performance and increased employee productivity typically arise from effective systems management, enhancements, or upgrades, rather than as a result of a breach. Similarly, enhanced user experience usually stems from well-designed user interfaces or system optimizations, rather than from experiencing a security incident. Thus, the focus on unauthorized access or disclosure underscores the critical risks associated with breaches and emphasizes the importance of robust security measures to protect sensitive information.
