Short Answer 
The response outlines the steps to address insider threats, starting with identifying potential sources like employees and contractors who may misuse their authorized access. It further explains the nature of data leakage, which can be unintentional or intentional, and emphasizes the importance of distinguishing between insider threats and external threats to enhance organizational security.
Step 1: Identify the Source of Insider Threats
Insider threats can arise from individuals who have authorized access to sensitive information. This includes:
- Employees who work within the organization.
- Contractors who are provided access to data and systems.
These individuals may misuse their access or fail to protect the information adequately.
Step 2: Understand the Nature of Data Leakage
Data leakage can occur in two main ways: unintentionally or intentionally. Key points include:
- Unintentional leaks happen due to errors or negligence while handling sensitive information.
- Intentional leaks occur when individuals intentionally share confidential data with unauthorized entities.
Both scenarios pose significant risks to the organization’s security.
Step 3: Distinguish Insider Threats from External Threats
It’s crucial to differentiate between insider threats and external threats like cybercriminals. Consider the following:
- Insider threats involve individuals who have authorized access to the organization’s systems.
- Cybercriminals and scammers typically operate externally and do not have authorized access.
Recognizing this distinction helps focus security efforts on the right potential risks within the organization.
