What are "internal security measures" designed to protect against?

Internal security measures are specifically designed to protect against threats that originate from within an organization. These measures address risks posed by employees or other individuals who have access to the organization's resources. Internal threats can include actions like sabotage, fraud, data leaks, or other malicious activities carried out by individuals who may have insider knowledge and access.

By implementing various internal security protocols, such as background checks, monitoring systems, access controls, and employee training programs, organizations can mitigate the risk of harm caused by those within their ranks. This strategic focus on safeguarding against internal threats is crucial as they can often be harder to detect and can inflict significant damage on an organization’s operations, reputation, and assets.

Other options focus on external threats or specific scenarios outside the internal structure of the organization, which would not fall under the scope of internal security measures. For instance, measures aimed at external thefts and break-ins or cybersecurity breaches typically concentrate on outside threats, while addressing employee incompetence involves different management strategies not necessarily categorized as internal security measures. Thus, "internal threats to an organization" is the most fitting description of the purpose of internal security measures.
