Key Takeaway
After assessing dozens of Singapore clinics, we see the same security gaps repeatedly: weak passwords, poor backups, delayed updates, flat networks, and undertrained staff. None require massive budgets to fix. This article shows you exactly what to do.
The Reality Check
These five mistakes appear in the majority of clinics we assess. They're not exotic vulnerabilities requiring expensive solutions—they're basic gaps that attackers exploit every day.
Good news: Fix these five issues, and you're ahead of most practices in Singapore.

Mistake #1: Weak Password Practices
What We See
Important
In the average clinic assessment, we find:
"clinic123" or "password123" as actual passwords
One login shared among all staff
Passwords on sticky notes attached to monitors
Same password for clinic system and personal email
Departed staff's passwords still working
Why Attackers Love This
Think of it Like This
Weak passwords are like leaving your clinic unlocked overnight with a sign saying "drugs inside." You're not just vulnerable—you're inviting trouble.
- Once inside with a password, attackers can:
- Download all patient records
- Install ransomware silently
- Read emails and steal more credentials
- Access anything that user could access
The Fix
| Change | Implementation |
| Length | Minimum 12 characters (longer = stronger) |
| Complexity | Mix of uppercase, lowercase, numbers, symbols |
| Uniqueness | Each staff member has their own account |
| MFA | Add a second factor (phone app or SMS) |
| Departures | Password changed within 24 hours of any resignation |
Pro Tip
Password managers (like 1Password or Bitwarden) let staff use strong, unique passwords without memorising them. Cost: ~S$5/user/month. Value: Enormous.

Mistake #2: Inadequate Backup Procedures
What We See
- "We back up... sometimes"
- Backup drive sitting next to the server (ransomware encrypts both)
- Backups never tested—assumption they work
- No encryption on backup data
- USB drives used for backup, easily lost or stolen
Why This Destroys Practices
Important
Ransomware scenario without backups:
Monday: Attack encrypts all files Tuesday-Friday: Trying to negotiate with criminals Week 2: Realising data is gone forever Month 2: Still manually reconstructing records Month 6: Practice closure
Same scenario with tested backups:
Monday: Attack encrypts files Tuesday: Restored from yesterday's backup Wednesday: Back to normal operations
The Fix: 3-2-1 Rule
| Number | Meaning |
| 3 | Three copies of your data |
| 2 | On two different storage types |
| 1 | One copy offsite/cloud |
- Critical requirements:
- Daily automated backups (don't rely on humans remembering)
- Backups encrypted
- At least one backup not connected to your network
- Monthly restoration tests (untested backups are useless)
Good to Know
The test is crucial. We've seen clinics discover their "backups" were empty files only when they needed them. Test by actually restoring files—not just checking that the backup ran.

Mistake #3: Delayed Security Updates
What We See
- Windows 7 still running (support ended 2020)
- "Remind me tomorrow" clicked for years
- Dental software from 2015 never updated
- "Updates break things" as an excuse
- No patch management process
Why This Matters
Important
WannaCry ransomware (2017) devastated hospitals globally. It exploited a vulnerability Microsoft had patched two months earlier.
Every affected organisation had the fix available. They just hadn't applied it.
Think of it Like This
Ignoring security updates is like ignoring recall notices on medical equipment. The manufacturer has identified a safety issue and provided a fix. Using unpatched software puts your patients at risk.
The Fix
| Priority | Timeline | Examples |
| Critical security | Within 7 days | Anything marked "critical" or "emergency" |
| Regular updates | Monthly cycle | Standard Windows, software updates |
| End-of-life | Plan replacement | Windows 7, Office 2010, unsupported systems |
- Enable automatic updates where possible
- Schedule monthly "update day" for manual updates
- Replace end-of-life systems—they cannot be secured

Mistake #4: No Network Segmentation
What We See
- Everything on one flat network:
- Patient records system
- Billing computer
- Staff personal phones
- Guest Wi-Fi
- Digital X-ray machine
Why This Is Dangerous
Think of it Like This
Imagine your clinic had no walls—just one open space where waiting room, consultation rooms, surgery, and storage were all connected. Anyone entering the waiting room could walk directly to your medication cabinet.
That's a flat network. One breach anywhere = access everywhere.
The Fix
| Network Segment | What's On It |
| Clinical | Patient records, medical devices |
| Administrative | Billing, email, general work |
| Guest | Patient/visitor Wi-Fi |
| Staff personal | Staff phones, personal devices |
Pro Tip
Implementation: Modern routers support VLANs. Your IT provider can set this up in a few hours. Cost: Usually just configuration time, no new hardware.

Mistake #5: Insufficient Staff Training
What We See
- One training session at hiring, never repeated
- Generic corporate training not relevant to healthcare
- "Click here to complete training" videos nobody watches
- Senior doctors exempt ("I don't need this")
- No testing to verify understanding
Why Staff Are Your Biggest Risk—And Asset
Important
90%+ of successful breaches start with a human action: clicking a link, opening an attachment, sharing a password.
Your technical controls are bypassed the moment someone clicks a phishing email.
What Effective Training Looks Like
| Component | Details |
| Frequency | Annual full training + quarterly refreshers |
| Relevance | Healthcare-specific scenarios, not generic corporate examples |
| Practical | Simulated phishing emails, hands-on exercises |
| Testing | Quiz at end—if staff can't pass, retrain |
| Universal | Everyone from cleaner to clinic director |
Pro Tip
Quick win: Send a simulated phishing email monthly. Track who clicks. Train those who do. This single practice dramatically reduces actual phishing success.

Bonus: 5-Minute Security Wins
These take almost no time or money:
Quick Checklist
1. Screen locks — Set auto-lock to 5 minutes maximum
Screen positioning — Angle monitors away from patient view
Paper security — Locked cabinet, not open shelf
Quarterly access review — Does everyone still need their access level?
Enable logging — Turn on audit logs in your clinic system
---
Your Next Steps
Good to Know
Prioritise by impact:
Passwords + MFA — Highest impact, stops most attacks
Backups — Ensures recovery if other defences fail
Updates — Closes known vulnerabilities
Network segmentation — Limits damage from any breach
Training — Strengthens your human firewall
None of these require enterprise budgets. They require attention and follow-through.
