Healthcare Data Security: How to Protect Patient Health Information?

Category: 

IT solutions in the healthcare industry have already simplified life for both doctors and patients. However, the issue of patients’ data privacy remains a sore point.

 

Even security measures in modern medical software can’t guarantee the safety of data from malicious actors and insider threats. In this article, we show statistics of healthcare data breaches, describe the benefits and risks of IT in the healthcare industry, find out why the current approach is troublesome, and define healthcare security vectors to enhance the protection of sensitive data.


Healthcare data breaches: hidden dangers and causes

 

The current situation with healthcare data security is extremely dangerous, as patient health information can be sold or used for crimes such as identity theft and insurance fraud, or to illegally obtain prescription drugs.

 

Outsider threats continue to present new challenges, but hidden insider threats are even more dangerous.

 

Just take a look at the 2019 Data Breach Investigations Report by Verizon. It says that privilege misuse and web applications are responsible for 81% of healthcare-related data incidents. Internal actors are responsible for 59% of all breaches in the healthcare industry.

The cost of healthcare data breaches

 

Knowing the size of the problem, it’s time to calculate its cost.

 

According to the 2019 Cost of a Data Breach Report by the Ponemon Institute, for the ninth year in a row, healthcare organizations have had the highest average cost associated with a data breach at $6.45 million – over 60% more than the global average for all industries.

 

Not only does the healthcare industry suffer from the highest costs for data breaches – it also takes the most time to identify and contain them: on average, it takes healthcare organizations 236 days to identify a problem and 93 days to contain it.

With all these numbers, it’s no wonder that the Health Insurance Portability and Accountability Act (HIPAA) pay lots of attention to unauthorized disclosures of protected health information (PHI), improper disposal of PHI, unauthorized access to PHI by cybercriminals and rogue healthcare employees, and other IT security and privacy breaches.

 

HIPAA has also added a Technical Safeguards section to its Compliance Checklist so that organizations with access to electronic Protected Health Information (ePHI) can ensure software security.

Electronic Health Record systems: benefits and vulnerabilities

 

Knowing that hacking of healthcare organizations is on the rise leads us to the question of what exactly is lacking in healthcare software and how we can protect sensitive data.

 

Almost all healthcare providers use Electronic Health Record (EHR) systems to store and manage sensitive healthcare data, including the following patient records:

 

  • Full name and birth date
  • Bank account information
  • Health data
  • Social Security number
  • Insurance information
  • Contact information
  • History of visits to healthcare professionals
  • Hospitalization records
  • Allergies and immunization status
  • Family history
  • List of prescribed medications
  • Medical images

 

The EHR initiative was born thanks to the Health Information Technology for Economic and Clinical Health Act (HITECH Act).

 

Benefits of EHR systems are enormous:

 

  • Streamline workflows
  • Consolidate all data in one place
  • Improve care coordination
  • Reduce healthcare disparities
  • Automatically update information
  • Share information among offices and organizations
  • Share media like medical images

 

However, EHR systems have several significant downsides when it comes to healthcare data security:

 

  • Consolidated data poses a great security risk. If perpetrators get access to the system, they can get full control over a wide range of personal patient data.
  • Apart from patient records, healthcare software can contain financial information, which attracts cybercriminals.
  • Phishing attacks may cause severe damage to data security if healthcare professionals aren’t taught how to identify them.
  • Malware and ransomware can reach EHR systems via downloads, software vulnerabilities, and even encrypted traffic. This malicious software may cause harm not only by stealing data but also by locking users out of their computers and demanding payment to regain access.
  • In healthcare, insider threats come from medical staff. Employees can cause trouble on purpose (stealing information to sell it) or by accident (disclosing it because of lack of cybersecurity education).

Why the current approach has problems

 


Most data protection solutions in healthcare are focused on establishing and maintaining a security perimeter, but most attacks and security breaches happen from within the system.

 

Perpetrators can be either employees or criminals trying to get access to the system from inside the building – for example, by using a public Wi-Fi connection or a USB device. To protect patient information stored in hospitals and other healthcare organizations from such insider threats, an employee activity tracking solution is required.

 

Almost all popular EHR systems like Cerner, Epic, Allscripts, and CureMD have some user tracking features, allowing you to see who accesses sensitive data. However, such features have their own limitations and vulnerabilities.

 

  • Usually, EHR systems don’t record the actions of users with privileged accounts, such as administrators. This allows those users to carry out malicious activity undetected.
  • Administrators can go undetected when changing the entitlement level of any user, including themselves. Thus, they can circumvent internal system monitoring and access personal patient data.
  • Even if access to sensitive data is recorded, it’s impossible to know how the data was used. Therefore, it’s complicated to detect malicious actions in time and prove violations.

 

To overcome all these drawbacks of EHR systems, it’s essential to use tracking software that monitors all user activity in compliance with the HIPAA audit checklist.

For electronic health record systems, auditing software that provides constant EHR system monitoring can significantly speed up the audit process, lessening your headaches and costs.
