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.
