Canadian Health Information Management Association Practice Exam

What is the most common type of security threat to a health information system?

1. Computer viruses

2. Environmental in nature

3. External to the healthcare entity

4. Internal to the healthcare entity

The correct answer is: Internal to the healthcare entity

The most common type of security threat to a health information system is internal to the healthcare entity. This type of threat often arises from individuals within the organization, such as employees, contractors, or third-party vendors who have access to sensitive data and systems. Internal threats can occur due to various reasons, including human error, negligence, or malicious intent, such as data theft or sabotage. Employees may inadvertently compromise security protocols by mishandling data or failing to follow established policies. Moreover, those with authorized access can intentionally exploit their privileges for personal gain or to harm the organization. This highlights the importance of not only providing robust technical defenses but also implementing strong access controls, regular training, and a culture of security awareness within the organization. While computer viruses, environmental threats, and external threats are significant concerns, the prevalence and impact of internal threats make them a leading security risk in health information systems. By addressing internal vulnerabilities, organizations can greatly enhance their overall security posture.
