Mohs Surgery Suite Security Risk Assessment Guide: Step-by-Step Checklist

Security Risk Assessment Purpose

The goal of a Mohs surgery suite security risk assessment is to protect patients, staff, specimens, and systems while meeting Security Compliance Regulations. You identify threats, evaluate existing safeguards, and prioritize improvements that reduce the likelihood and impact of security incidents.

Objectives

• Safeguard protected health information (PHI) through strong Electronic Health Record Protections and Data Encryption.
• Prevent unauthorized entry and theft with robust Access Controls and Surveillance Systems.
• Preserve clinical continuity and specimen integrity by hardening critical equipment and workflows.
• Formalize Security Incident Reporting and Incident Response Plans that are timely, tested, and role-based.
• Demonstrate alignment with applicable Security Compliance Regulations and internal policies.

Expected Outcomes

• A documented risk register with likelihood, impact, and risk ratings for each finding.
• A prioritized remediation roadmap with owners, resources, and timelines.
• Metrics and monitoring methods to verify control effectiveness over time.

Pre-assessment Preparation

Start by defining scope, assembling the right team, and gathering evidence. Clear preparation ensures consistent, defensible results and faster remediation.

Checklist

• Form a cross-functional team: Mohs surgeon, nursing lead, histotechnician, practice manager, IT/security, facilities, and privacy/compliance.
• Define scope and boundaries: check-in, changing areas, lab/cryostat room, procedure rooms, server/network closets, EHR workstations, storage, and waste streams.
• Collect artifacts: floor plans, key/badge lists, camera maps, visitor logs, policies, device inventory, network diagrams, vendor contracts, and recent incident reports.
• Set evaluation criteria: risk scales, acceptance thresholds, and mapping to Security Compliance Regulations.
• Plan methods and schedule: interviews, walkthroughs, control testing, and tabletop drills for Incident Response Plans.

Physical Security Evaluation

Assess how people enter, move, and work in the suite, and how critical assets are protected. Focus on layered barriers that deter, detect, delay, and respond.

Access Controls

• Verify badge-only entry to procedure and lab areas; disable generic badges; enforce least privilege and timely offboarding.
• Harden doors, hinges, and strike plates; use door position sensors and alarms for critical rooms.
• Implement visitor management: government ID verification, badges, escorts, and visitor logs retained per policy.

Surveillance Systems

• Confirm camera coverage of entrances, corridors to the lab, drug/chemical storage, and server closets; minimize blind spots.
• Check retention periods, time synchronization, and secure storage of recordings; restrict access to footage with audit trails.

Specimen, Equipment, and Environment

• Use locked, labeled storage for slides, blocks, reagents, and controlled substances; document chain-of-custody.
• Secure cryostats, microscopes, and imaging devices; disable default accounts and unauthorized USB ports.
• Protect power, HVAC, and flood sensors for areas housing equipment and records; maintain maintenance logs.

Information Security Assessment

Evaluate controls that protect data confidentiality, integrity, and availability across EHRs, endpoints, and networks. Emphasize Electronic Health Record Protections and Data Encryption.

Electronic Health Record Protections

• Enforce unique IDs, MFA, and role-based access; enable automatic logoff and session timeouts at shared workstations.
• Turn on audit logging and routine review for access anomalies and “break-the-glass” events.

Data Encryption and Endpoint Security

• Use full-disk encryption on laptops and workstations; encrypt removable media or disable it via policy.
• Require TLS for EHR, email, imaging, teledermatology, and VPN; block legacy ciphers and insecure protocols.
• Harden endpoints with EDR/antimalware, patching SLAs, screen privacy filters, and kiosk mode where appropriate.

Network and Identity Controls

• Segment clinical, administrative, and guest networks; restrict lateral movement with firewalls and ACLs.
• Secure Wi‑Fi with strong authentication and modern standards; rotate keys and monitor for rogue APs.
• Apply least privilege and just-in-time elevation; enforce rapid account deprovisioning for staff and vendors.

Resilience and Vendor Management

• Define backup RPO/RTO; keep at least one immutable or offline copy; test restoration regularly.
• Assess cloud/EHR vendors and device manufacturers; confirm incident notification terms and secure data handling.

Staff Training and Awareness

People are your first line of defense. Build practical, role-based training that turns policies into daily habits.

Program Essentials

• Onboarding and annual refreshers covering PHI handling, clean desk, secure messaging, and device use.
• Phishing simulations, privacy rounds, and short microlearnings tailored to the Mohs workflow.
• Clear Security Incident Reporting: what to report, how to report, and required timelines.

Role-Specific Focus

• Front desk: identity verification, visitor control, and secure printing.
• Clinical/lab: specimen labeling, camera/phone restrictions, workstation locking, and chain-of-custody.
• Leads/managers: approval of Access Controls, remediation tracking, and Incident Response Plans activation.

Risk Identification and Analysis

Translate observations into discrete risks, then rate and prioritize them. Use consistent criteria to ensure fairness and transparency.

Build the Risk Register

• Document threats such as tailgating, lost devices, ransomware, misconfigured EHR permissions, or camera blind spots.
• Record affected assets, existing controls, and evidence (photos, logs, ticket numbers).

Scoring and Prioritization

• Score likelihood and impact, derive overall risk, and distinguish inherent vs. residual risk.
• Flag high-risk items that require immediate containment or compensating controls.

Risk Mitigation Strategies

Choose targeted controls that reduce the most risk with the least friction. Balance physical, administrative, and technical safeguards.

Quick Wins

• Rekey or reprogram doors; remove shared accounts; enforce MFA and workstation lock policies.
• Add privacy screens, adjust camera angles, and label/secure portable media and devices.

Strategic Controls

• Implement centralized identity governance, network segmentation, and automated patching.
• Strengthen Data Encryption standards and certificate management across all clinical systems.
• Formalize Incident Response Plans with detection, containment, eradication, recovery, and lessons learned.
• Integrate business continuity and disaster recovery testing with clinical downtime procedures.

Governance and Measurement

• Assign control owners, budgets, and deadlines; track progress in a living remediation plan.
• Monitor KPIs: time to remediate, encryption coverage, patch compliance, and training completion.

Documentation and Reporting

Clear documentation proves due diligence and accelerates improvement. Report findings in ways clinicians and leaders can act on.

What to Produce

• Executive summary, scope, and methods; detailed findings with evidence; risk heat map and register.
• Action plan with milestones, dependencies, and required resources; acceptance or exception records where needed.

Security Incident Reporting

• Define thresholds for immediate escalation; document who to notify, how, and within what timeframe.
• Capture root cause, corrective actions, and tracking to closure; feed insights back into training and controls.

Conclusion

A disciplined, repeatable assessment protects patients and operations while aligning with Security Compliance Regulations. By tightening Access Controls, enhancing Surveillance Systems, strengthening Electronic Health Record Protections, and validating Incident Response Plans, you reduce risk and sustain trust.
