Startling statistics from the Office for Civil Rights (OCR) reveal that in the first half of 2023, the healthcare sector endured no less than 295 breaches, casting a long shadow over the data security landscape. These breaches compromised the personal information of over 39 million individuals. What's even more concerning is the financial toll on healthcare organizations, as each breach incurred an average cost of $10.1 million in 2022. This represents a substantial 9.4% increase from the previous year, significantly higher than any other sector's data breach expenses.
Healthcare data breaches are the unauthorized access, use, disclosure, disruption, modification, or destruction of protected health information (PHI). PHI is any information that can be used to identify an individual and that relates to their past, present, or future physical or mental health condition, the provision of health care to them, or the payment for their health care.
Healthcare data breaches can happen in a number of ways, including:
Hacking: Hackers may gain access to hospital computer systems through phishing attacks, malware infections, or other vulnerabilities.
Physical theft: Laptops, smartphones, and other devices containing PHI may be stolen from hospital employees or patients.
Human error: Hospital employees may accidentally misplace or email PHI to the wrong person.
Healthcare data breaches can have serious consequences for patients. If their PHI is compromised, they could be at risk of identity theft, medical fraud, and other forms of harm. For example, a criminal could use a patient's stolen PHI to open fraudulent credit accounts in their name or to obtain prescription drugs.
There are a number of things that Hospitals can do to prevent data breaches, including:
Implementing strong security measures, such as firewalls, intrusion detection systems, and data encryption.
Educating employees about cybersecurity best practices, such as phishing awareness and password management.
Having a plan in place for responding to a data breach if one does occur.
Patients can also help to protect their own data by being careful about what information they share online and taking steps to protect their devices from malware. For example, patients should only share their PHI with trusted healthcare providers and they should use strong passwords and two-factor authentication for all of their online accounts.
Threat modeling can help hospitals to:
Identify potential threats: This includes both internal threats, such as malicious employees, and external threats, such as hackers and cybercriminals.
Assess the likelihood and impact of threats: This information can then be used to prioritize security resources and focus on the most critical threats.
Identify and mitigate vulnerabilities: Once vulnerabilities have been identified, hospitals can take steps to mitigate them, such as implementing security patches or changing policies and procedures.
Threat modeling can be used to protect all aspects of healthcare data, including patient records, financial data, and intellectual property.
Here are some additional tips for preventing Healthcare data breaches:
- Use strong passwords and two-factor authentication for all online accounts.
- Be careful about what information you share online. Only share your PHI with trusted healthcare providers.
- Keep your devices up to date with the latest security patches.
- Use a firewall and antivirus software on your devices.
- Be aware of phishing scams and other social engineering attacks.
- Report any suspicious activity to your healthcare provider immediately.
Overall, threat modeling is a valuable tool that can help hospitals to prevent healthcare data breaches. By identifying and mitigating potential threats and vulnerabilities, hospitals can protect their patients' data and reduce the risk of a breach.
