Key Takeaway
Starting point: 42% compliance score, no encryption, shared passwords, no incident plan. End result: 87% compliance score in 30 days with minimal disruption to patient care. Cost: S$15,200/year after PSG grant. Less than one ransomware attack would cost.

The Practice: XYZ Dental

CharacteristicDetails
LocationCentral Singapore
Staff3 dentists, 5 assistants, 2 admin
Years operating15+
Active patients~3,000
Starting compliance score42/100

Think of it Like This
Like many established practices, XYZ Dental's technology had grown organically—functional but never audited for security. Think of it like a clinic that's been operating for years but never had a full compliance review of their sterilisation procedures.

The Wake-Up Call

Dr. Lim, the practice owner, attended a dental association seminar on HIB compliance. What he learned disturbed him:

What He Discovered

Important
Critical gaps found:
  • Patient records on aging server with no encryption
  • Backups manual and inconsistent (sometimes weeks between)
  • All staff using shared login credentials
  • No incident response plan
  • Minimal audit logging—couldn't track who accessed what
  • With HIB enforcement approaching, Dr. Lim needed to act fast—but couldn't shut down for weeks to fix everything.

    Week 1: Discovery

    Our Assessment Process

    AreaMethod
    Technical infrastructureSystem scans, configuration review
    Policies & proceduresDocument review, gap analysis
    Staff practicesInterviews, observation
    Data flowsMapping where patient data lives and moves
    Risk assessmentThreat modelling, vulnerability prioritisation

    The Findings

      Critical (Must Fix Immediately):
    • Server vulnerable to ransomware (no endpoint protection)
    • Backups on same network as primary data (ransomware encrypts both)
    • No multi-factor authentication
    • All staff could access all patient data (no role-based restrictions)
      Moderate (Fix Soon):
    • Outdated software on workstations
    • No formal access control policy
    • Incomplete audit logging
    • Security training last done: never
      Minor (Address When Possible):
    • Password policy not enforced
    • Screen timeout set to 30 minutes (should be 5)
    • Some paper records on open shelves

    Starting Score: 42/100

    Good to Know
    Passing threshold for HIB compliance: 80/100

    Gap to close: 38 points in 30 days

    Week 1-2: Planning

    Prioritisation Logic

    Pro Tip
    Our approach: Fix the highest-risk items first. If a ransomware attack hit during our work, we wanted critical defences in place.

    PriorityItemsTiming
    ImmediateEndpoint protection, backups, MFA, loggingWeek 1-2
    Short-termAccess controls, network segmentation, updates, trainingWeek 2-3
    OngoingPolicies, incident plan, monitoring, validationWeek 3-4

    Resource Reality

    ResourceRequirement
    Dr. Lim's time3 hours total (kick-off, mid-point check, final review)
    Staff time2 hours (training session)
    DowntimeLess than 2 hours total (after-hours work)
    BudgetS$4,000 setup + S$2,200/month
    After PSGS$2,000 setup + S$1,100/month

    ---

    Week 2: Foundation Work

    Monday-Tuesday: Endpoint Protection

    • Deployed enterprise-grade antivirus/anti-malware on all 12 devices
    • Configured real-time threat monitoring
    • Updated all operating systems and software patches

    Wednesday-Thursday: Backup Overhaul

    Good to Know
    The 3-2-1 implementation:
  • 3 copies: Server, local backup, cloud backup
  • 2 media types: Physical drive + cloud storage
  • 1 offsite: Cloud backup isolated from clinic network
    • Implemented automated daily cloud backups
    • Tested restoration (successfully recovered test files)
    • Encrypted local backup copies

    Friday: Access Security

    • Enabled MFA for all user accounts
    • Created individual accounts (eliminated shared logins)
    • Configured comprehensive audit logging

    ---

    Week 3: Access & Network

    Monday-Tuesday: Role-Based Access

    RoleAccess Level
    DentistsFull clinical records
    Dental assistantsClinical records for assigned patients
    Admin staffScheduling, billing—no clinical notes

    Wednesday-Thursday: Network Segmentation

    • Clinical systems isolated from guest Wi-Fi
    • Firewall rules preventing lateral movement
    • Staff personal devices on separate network

    Friday: Staff Training

      2-hour session covering:
    • Why these changes matter (HIB requirements)
    • New login procedures (individual accounts, MFA)
    • Recognising phishing attempts
    • What to do if something seems wrong
    • Quick reference guides distributed

    ---

    Week 4: Documentation & Validation

    Monday-Tuesday: Policy Creation

    • Data protection policy
    • Information security policy
    • Acceptable use policy
    • Incident response plan

    Wednesday-Thursday: Testing

    Pro Tip
    The real test: We ran a simulated incident response exercise. Could the team notify MOH within 2 hours? Answer: Yes.
    • Tabletop exercise for breach scenario
    • Validated all technical controls
    • Tested backup restoration again

    Friday: Final Assessment

    New Score: 87/100

    Good to Know
    ROI Perspective:

    Average ransomware attack cost: S$100,000+

    Annual protection cost: S$15,200

    One prevented attack pays for 6+ years of service.

    Lessons Learned

    What Worked

    FactorWhy It Mattered
    Clear communicationStaff understood the "why," not just the "what"
    After-hours workZero disruption to patient care
    Phased approachManageable changes, not overwhelming overhaul
    Quick wins firstEarly improvements built momentum and confidence

    What We'd Do Differently

    Pro Tip
    Dr. Lim's advice to other clinic owners:

    "Start earlier. We got it done in 30 days, but it was tight. With 2-3 months, we could have been more thorough and less stressed. Don't wait until you're worried—by then you're already behind."

    Dr. Lim's Experience

    > "Before this, I was constantly worried about compliance and security. I knew we had problems but had no idea where to start or what to prioritise. > > The Synexo team made it seamless. I spent maybe 3 hours total on this—everything else happened in the background. The staff training was practical, not theoretical, and my team actually understood it. > > Now I have one less thing keeping me up at night. I can focus on what I actually trained to do: taking care of my patients."
