Common SRA Findings in Neurology Practices
Unencrypted DICOM Network Communications
Many DICOM networks transmit imaging data without encryption. This allows potential interception of neuroimaging data during network transmission.
Inadequate Access Controls on Imaging Archives
DICOM archives may allow broad access to all imaging studies. Role-based restrictions should limit viewing to clinicians involved in patient care.
EEG System Network Integration Without Segmentation
EEG systems connected to clinical networks may lack proper segmentation, creating risk of compromise from other network systems.
Unattended Clinical Workstations With Active Sessions
Neurology workstations displaying patient neuroimaging may remain unlocked, allowing unauthorized viewing of sensitive imaging data.
Weak Authentication for Telemedicine Platforms
Remote consultation systems may use single-factor authentication, increasing risk of unauthorized access to neuroimaging and patient data.
Insufficient Audit Logging of Imaging Access
Some imaging systems lack comprehensive audit logs showing who accessed which images and when, limiting breach detection capability.
Portable Device Data Not Encrypted
EMG and portable diagnostic devices may store patient neurological data without encryption, creating exposure if devices are lost or stolen.
Inconsistent Image Data Retention Practices
Neuroimaging data may be retained beyond clinical necessity on workstations or portable devices, increasing breach risk.

Frequently Asked Questions
Your SRA should address DICOM security standards including DICOM PS3.15 (Security and System Management Profiles), which specifies encryption requirements and secure communication standards. The SRA should verify that DICOM storage systems implement user authentication, secure access controls, audit logging, and encrypted communications. Additionally, ensure compliance with NIST cybersecurity standards and FDA guidance on medical device security. Your SRA should include assessment of DICOM archive access controls, encryption of DICOM files at rest and in transit, and secure DICOM network configuration.
Real-time EEG monitoring systems require comprehensive security measures. Implement network segmentation to isolate EEG systems from general clinical networks. Use encrypted wireless protocols for data transmission if systems are wireless-enabled. Implement access controls restricting viewing of real-time EEG data to assigned clinical staff. Ensure audit logging of all EEG data access and system modifications. For portable EEG monitoring, devices should have automatic screen locks, encryption of stored data, and secure deletion procedures. Regular firmware updates and vulnerability assessments of EEG equipment should be included in your security program.
Your telemedicine security assessment should evaluate encryption of video and audio communications, multi-factor authentication for provider and patient access, secure data transmission when sharing neuroimaging or EEG waveforms, audit logging of all remote consultations and data access, access controls preventing unauthorized consultation viewing, automatic session timeouts, and verification of device security for remote devices. Assess whether telemedicine platforms use HIPAA-compliant video conferencing with end-to-end encryption. Verify that screen sharing of patient data uses secure methods with proper access controls. Regular penetration testing of telemedicine platforms is recommended to identify vulnerabilities.
For legacy neuroimaging equipment lacking native security features, implement compensating controls. Network segmentation can isolate older systems from general networks. Use a dedicated DICOM gateway with encryption and access controls to secure communications. Implement network access control (NAC) to restrict connections. Deploy intrusion detection to monitor for unusual activity. Increase physical security and monitoring of legacy systems. Work with equipment vendors to determine if firmware updates or security patches are available. Document the risk acceptance for equipment where remediation is not feasible, including business justification and planned replacement timelines.
