Preventing unauthorized access involves implementing security measures to protect systems, data, and physical assets.
Understanding unauthorized access
Unauthorized access is any attempt to use or retrieve information from healthcare systems without proper authorization. This can be via:
- Cyberattacks like hacking or phishing.
- Insider threats, where employees misuse their access.
- Physical breaches, such as theft of devices or access to restricted areas.

Strategies to prevent unauthorized access
Strengthen digital security measures
- Use multi-factor authentication (MFA): Multi-factor authentication requires users to verify their identity through two or more methods, such as a password and a biometric scan, significantly reducing the risk of unauthorized logins.
- Implement role-based access control (RBAC): Restrict access to sensitive information based on employee roles, so that only authorized personnel can view or edit critical data.
- Encrypt data: HIPAA’s Security Rule considers encryption an “addressable specification;” however, encrypting patient records ensures that even if data is intercepted, it cannot be read without the decryption key.
- Regularly update systems and software: Outdated software often contains vulnerabilities that cybercriminals can exploit. Regular updates and patches can close security gaps.
Enhance physical security
- Secure workstations and devices: Ensure that all computers and portable devices are password-protected and locked when not in use. Employ screen privacy filters in shared spaces.
- Control access to physical spaces: Use key cards, biometric scanners, or PIN codes to restrict entry to sensitive areas like server rooms or medical records storage.
- Monitor and log visitor access: Maintain a log of all visitors and their purpose for being in secure areas.

Foster a culture of security awareness
- Employee training: Educate staff on the importance of protecting patient data and recognizing security threats like phishing emails or suspicious behavior.
- Enforce policies: Establish clear guidelines on data access and usage. Regularly audit compliance with these policies.
- Encourage reporting: Create a system where employees can report potential security risks without fear of retaliation.
Monitor and audit systems continuously
- Real-time monitoring: Use advanced monitoring tools to detect and respond to unauthorized access attempts in real time.
- Conduct security audits: Regular audits help identify vulnerabilities and ensure compliance with regulations like HIPAA.
- Log access: Maintain detailed logs of who accessed what information and when to trace sources of potential breaches.

Develop a robust incident response plan
Even with preventive measures, breaches can occur. A well-defined incident response plan ensures quick action to mitigate damage, such as:
- Isolating affected systems.
- Notifying relevant stakeholders.
- Conducting a post-incident review to prevent future occurrences.

FAQs
What should I do if I suspect unauthorized access has occurred?
- Immediately lock accounts or systems that may have been compromised.
- Notify relevant stakeholders and authorities.
- Investigate the breach, determine its scope, and take corrective action.
- Document the incident for future analysis and to prevent recurrence.
What are some signs of unauthorized access?
Look for these warning signs:
- Unusual login locations or times.
- Unexpected changes in system settings or files.
- Missing or corrupted data.
- Unrecognized devices connected to the network.
- Login attempts with locked accounts.

How can organizations secure remote workers against unauthorized access?
- Require VPN usage for secure connections.
- Implement device management tools to monitor and control access.
- Use cloud-based security measures like CASBs (Cloud Access Security Brokers).
- Conduct cybersecurity training tailored for remote environments.
