HEALTHCARE SECURITY OPERATIONS
MediSOC provides around-the-clock monitoring and supports analysis, notification, initial response, and continuous improvement within the agreed operating scope.
CURRENT GUIDANCE / 2026
Regulation and threats continue to change. MediSOC helps healthcare providers build the operating discipline needed to keep security measures current.
Following an amendment to the Ordinance for Enforcement of the Medical Care Act, administrators of hospitals, clinics, and other covered healthcare institutions are required to take necessary measures.
MHLW: Cybersecurity in healthcareMHLW updated its Guidelines for the Safety Management of Medical Information Systems to Version 7.0 in June 2026.
MHLW: Guideline Version 7.0The current checklist emphasizes contact structures, backups, recovery procedures, and business continuity planning for cyberattacks.

OPERATING MODEL
Security does not end at deployment. We connect governance, infrastructure, day-to-day operations, and improvement in one operating model.
Understand
Building the groundwork before deployment. From current assessment to policy development.
Prepare
Deploying and configuring the core defense tools and equipment.
Operate
24/7 monitoring and initial response support by security specialists.
Improve
Elevating people and processes to sustain security standards.
COVERAGE MAP
Six capabilities work across three layers: visibility, interpretation, and containment. The exact scope is designed around each healthcare environment.
OBSERVE
Maintain a working picture of assets and vulnerabilities to support better decisions.
Organize PCs, servers, and network equipment so unknown or unmanaged assets are easier to review.
Organizes information on servers, endpoints, and network equipment so changes and unknown devices can be reviewed. Supports the ongoing asset inventory expected by the current checklist.
Review OS and software update status, then organize response priority and patch planning.
Reviews operating system and software update status, then helps prioritize action. Patch planning is shaped around the operational constraints of each healthcare environment.
INTERPRET
Review access and detection data to identify signals that call for action.
Support operating practices for collecting, retaining, and reviewing critical system access logs.
Establishes operating practices for collecting, retaining, and reviewing access logs from critical systems, supporting traceability when an incident must be investigated.
Specialists review detection data, assess priority, and connect relevant signals to notification and initial response.
Combines automated detection with specialist review to assess the nature and priority of a signal, then connect it to the appropriate notification and initial response.
CONTAIN
Operate network and endpoint controls to support actions that limit impact.
Review traffic and defense policies, with continuing support for appropriate configuration changes and updates.
Reviews traffic and defense policies, supporting configuration changes and updates appropriate to the environment. Maintains protection at the network perimeter as an ongoing operation.
Detect suspicious endpoint behavior and support impact review, isolation, and remediation within the agreed scope.
Detects suspicious endpoint behavior and supports initial actions such as impact assessment, isolation, and remediation. Available actions depend on the selected product and agreed operating scope.
RESPONSE PROTOCOL
MediSOC connects signal detection, analysis, notification, containment, verification, and reporting as one operating process.
This scenario illustrates the operating approach. Actual procedures, response times, and actions depend on the contract and each healthcare environment.
Detect
Monitor changes across networks, endpoints, and logs, then surface events that require review.
Analyze
Review the signal, possible false positives, and the potential impact on clinical systems.
Notify
Use the agreed contact route to communicate the situation and recommended initial actions clearly.
Contain
Within the agreed scope, support actions such as traffic restrictions or endpoint isolation.
Verify
Track for additional signals and support the provider's internal decisions about recovery and continuity of care.
Report
Document the event, actions, and remaining issues to support prevention and operational improvement.
OUTCOMES BY ROLE
Management, IT teams, and clinical staff each need a different outcome from the same security operation.
DEPLOYMENT LEDGER
We develop a practical deployment plan while reviewing impact on existing systems and defining responsibilities. Timing varies by scale, architecture, and scope.
Detailed assessment of current systems and security challenges
Requirements analysis, optimal plan and quotation
Engineer visit to verify network and equipment
Equipment installation, configuration, and initial security measures
Transition to monitoring based on the agreed assets, contact routes, and response scope
QUESTIONS / BEFORE WE START
Deployment conditions and operating scope are confirmed after reviewing each provider's environment.
We review network architecture and operating constraints on site, then propose a deployment approach designed to limit impact on clinical systems.
Alongside 24/7 monitoring, we support incident notification and initial actions within the agreed scope. Reporting content and frequency are defined during deployment.
We assess suitability and an appropriate scope based on bed count, endpoint volume, and network architecture. Tell us about your current environment to begin.
We continue to review current MHLW guidance and checklists and recommend necessary changes. The specific scope and any additional work are confirmed according to the engagement agreement.
START WITH VISIBILITY
Your architecture and concerns do not need to be fully organized. We will review the current environment with you and define the security and operating scope that is actually needed.
If available, share your facility scale, approximate endpoint count, and current concerns when you contact us.
