Healthcare Data Security: Challenges & Best Practices

Why Healthcare Is a Prime Cyber Target 

Healthcare systems hold highly sensitive data—patient names, diagnosis records, billing information—all in one place. This makes them ideal targets for cybercriminals. Downtime is costly in healthcare, so attackers know providers are more likely to pay. 

Many organizations are still using outdated systems, which creates vulnerabilities. This is where Trawlii can assist by helping healthcare organizations modernize their digital infrastructure while keeping Electronic Health Record (EHR) security top of mind. 

Regulatory Landscape & 2025 Updates 

HIPAA remains the core framework, but 2025 introduces tighter standards around cloud usage, mobile devices, and breach reporting. Providers are expected to demonstrate continuous compliance—not just check boxes during audits. 

Trawlii helps its clients stay updated with evolving regulatory needs and adopt HIPAA compliance best practices across every layer of their systems, from internal access controls to vendor management. 

7 Biggest Data-Security Challenges in Healthcare 

Let’s take a closer look at the top healthcare cybersecurity challenges you should be aware of in 2025: 

1. Legacy Systems & Outdated Tech 

Older software and hardware are still in use at many healthcare facilities. These systems don’t receive regular security updates, making them an easy target for cyberattacks. 

2. IoMT & Expanding Attack Surface 

The Internet of Medical Things (IoMT) includes devices like smart IV pumps and heart monitors. These tools increase efficiency but also create more points where hackers can try to break in. 

3. Insider Threats & Human Error 

Not all threats come from outside. Simple mistakes—like clicking on a phishing email or mismanaging files—can result in major Protected Health Information (PHI )breaches. 

4. Ransomware & Double-Extortion 

Ransomware has evolved. Today’s cybercriminals don’t just lock your data; they also threaten to expose it unless you pay up—this is called double-extortion. 

5. Cloud Misconfigurations 

A large number of healthcare providers now keep patient data in the cloud. But if those cloud systems aren’t set up securely, they can leave sensitive information wide open to attackers. 

6. API & Interoperability Risks 

Systems use APIs to exchange information and work together. If these are poorly protected, they can expose large volumes of data. 

7. Third-Party Vendor Weak Links 

Healthcare organizations often work with external vendors—billing companies, IT providers, etc. If one of them has weak security, it can put your entire network at risk. 

10 Best Practices to Fortify Patient Data 

To strengthen healthcare data security in 2025, here are ten practical steps every organization should take: 

1. Implement Zero-Trust Architecture 

In a zero-trust healthcare setup, nobody is trusted automatically—not even users inside the system. All users and devices must be authenticated before they can enter the system. 

2. Encrypt & Tokenize PHI 

Encryption scrambles sensitive information, making it useless if stolen. Tokenization replaces sensitive data with harmless placeholders, reducing risk even further. 

3. Enforce MFA Everywhere 

Multi-Factor Authentication(MFA) adds an extra layer of login security. Even if someone steals a password, they can’t log in without the second verification step. 

4. Deploy AI-Driven SIEM 

Security Information and Event Management (SIEM) tools, especially those powered by AI, can catch threats in real-time and reduce response times dramatically. 

5. Run Quarterly Risk Assessments 

Conduct risk reviews every three months to identify new vulnerabilities and ensure your systems stay up to date. 

6. Screen Vendors for SOC 2 / ISO 27001 

Before working with any vendor, make sure they meet security standards like System and Organization Controls 2 (SOC 2) or International Organization for Standardization(ISO) 27001. If they’re not secure, your data isn’t either. 

7. Conduct Ongoing Staff Security Training 

Employees are often the weakest link. Regular security education helps team members spot threats like phishing emails and use safe practices when handling sensitive data. 

8. Maintain Incident-Response Playbooks 

Every organization should have a clear plan for how to respond to a data breach. It ensures timely responses, controls potential damage, and helps maintain compliance. 

9. Monitor Compliance Continuously 

Don't wait for a yearly audit. Use tools that track your Health Insurance Portability and Accountability Act(HIPAA) compliance best practices in real-time and alert you to any gaps. 

10. Map Data Lineage End-to-End 

Know where your data comes from, where it goes, and how it's stored. This visibility helps you spot risks and improves PHI breach prevention. 

Emerging Technologies to Watch 

Innovative tech is reshaping healthcare data security. AI is being used to detect unusual activity early. Blockchain is being tested for secure, tamper-proof patient records. These tools may become essential in the near future.
