Unauthorized data disclosure: The exposure of sensitive or confidential information to unauthorized parties, either intentionally or unintentionally1.
Proactive approach: An approach that anticipates and prevents potential problems or threats before they occur, rather than reacting to them after they happen2.
Incident response plan: A set of policies, procedures, and tools that guide an organization’s actions in the event of a data breach or security incident3.
A proactive approach to minimizing the potential impact of unauthorized data disclosure is to have an incident response plan. An incident response plan helps an organization to:
Detect and contain the incident as quickly as possible
Analyze the scope, cause, and impact of the incident
Eradicate the threat and restore normal operations
Communicate with internal and external stakeholders
Learn from the incident and improve security measures
An incident response plan enables an organization to reduce the damage and disruption caused by unauthorized data disclosure, as well as to comply with relevant laws and regulations that require timely notification and remediation of data breaches3.
The other options are not as effective as an incident response plan in minimizing the potential impact of unauthorized data disclosure, because they do not address the root cause or the response of the incident. Key risk indicators (KRIs), which are metrics that measure the level of risk exposure or the likelihood of a risk event, may help to monitor and manage the risk of unauthorized data disclosure, but they do not prevent or respond to the incident. Data backups, which are copies of data stored in a separate location or medium, may help to recover the data that was lost or corrupted due to unauthorized data disclosure, but they do not protect the data that was exposed or stolen. Cyber insurance, which is a type of insurance that covers the financial losses and liabilities arising from cyberattacks or data breaches, may help to mitigate some of the costs and risks associated with unauthorized data disclosure, but it does not prevent or resolve the incident.
