Study Notes

Introduction to Health Information Systems (HIS) Security

HIS security is crucial for trust and confidence in digital health information.
- Breaches in HIS security can lead to reputational and financial harm, harm to patients, and vulnerability of patient information.

The CIA Triad of Information Security

Confidentiality: Protecting patient's personal health information from unauthorized disclosure.
- Promotes a trusting environment for patients to seek healthcare.
- HIPAA requires institutions to implement policies protecting the privacy of patients' electronic information.
Integrity: Ensuring the accuracy and reliability of healthcare data.
- Only authorized users should access patient data.
- Data should not be altered or destroyed.
Availability: Making the HIS accessible for end users.
- Proper hardware maintenance, system upgrades, communication bandwidth, and disaster recovery are essential.

Security Threats in Health Care

Security threats target valuable organizational information and aim to disrupt normal operations.
Attackers exploit system vulnerabilities using various methods and tools.
System administrators must understand security aspects to develop protective measures and limit vulnerabilities.

Human Threats

Malicious threats: Deliberate acts to harm or disrupt an organization.
- Insiders: Disgruntled or malicious employees with knowledge of security measures.
- Outsiders: Hackers seeking to disrupt services or steal information.
Non-Malicious threats: Unintentional errors by untrained employees who are unaware of security threats and vulnerabilities.
- Data entry errors: Mistakes in data entry can lead to loss, damage, or alteration of valuable data.
- Programming errors: Errors in code can crash systems or create vulnerabilities.

Natural Disasters

Natural disasters like earthquakes, hurricanes, floods, and fires can severely damage computer systems.
Potential consequences include loss of information, downtime, and damage to hardware.
Disaster recovery plans and contingency plans are crucial for preparedness.
Terrorist attacks and riots, though human-caused, are classified as natural disasters due to their disruptive nature.
