What to Do After a Data Breach: Medical Clinic Guide

Home » What to Do After a Data Breach: Medical Clinic Guide

Any incident that results in personal information being lost, accessed or disclosed without authorisation should be taken seriously.

For healthcare providers, the stakes are particularly high because patient health information is considered sensitive information under Australian privacy law.

Step 1: Contain the breach

The first priority is to stop the incident from getting worse.

This may include:

• Disconnecting affected devices from the network.
• Disabling compromised user accounts.
• Changing passwords.
• Blocking unauthorised access.
• Contacting your IT provider immediately.

The faster the breach is contained, the greater the chance of reducing its impact.

Avoid deleting evidence or making unnecessary system changes until the cause has been investigated.

Step 2: Assess what happened

Once the situation is stable, determine:

• What information was involved?
• How did the breach occur?
• Who has been affected?
• Has the information been copied, stolen or simply exposed?
• Is the breach ongoing?

Good record keeping during this stage is important, particularly if regulators or insurers become involved.

Step 3: Determine whether the breach is notifiable

Under Australia’s Notifiable Data Breaches (NDB) scheme, organisations covered by the Privacy Act must notify affected individuals and the Office of the Australian Information Commissioner (OAIC) if an eligible data breach is likely to result in serious harm. The OAIC recommends completing a reasonable and expeditious assessment within 30 days where there are reasonable grounds to suspect an eligible breach may have occurred.

Not every incident is automatically reportable, but every breach should be assessed carefully.

Healthcare providers should have a documented process for evaluating incidents and understanding their notification obligations.

Step 4: Notify the right people

If the breach is determined to be an eligible data breach under the NDB scheme, the organisation must notify the OAIC and affected individuals as soon as practicable after completing the assessment. The notification should explain what happened, what information was involved and the steps individuals can take to protect themselves.

Open and timely communication helps maintain trust and allows patients to take appropriate action where necessary.

Step 5: Learn from the incident

Once the immediate response is complete, the clinic should review what happened and identify ways to reduce the risk of future incidents.

Questions to consider include:

• Did the attack start with phishing?
• Was multi-factor authentication enabled?
• Were staff adequately trained?
• Were backups working?
• Were software updates current?
• Did security monitoring identify the issue quickly?
• Are policies and procedures still appropriate?

A data breach should become a learning opportunity, not just a recovery exercise.

Prevention is better than recovery

The most effective way to reduce the impact of a data breach is to lower the likelihood of one occurring.

Practical measures include:

• Multi-factor authentication (MFA)
• Regular staff cyber awareness training
• Strong password policies
• Secure email filtering
• Endpoint protection
• Routine software updates
• Reliable backup and disaster recovery planning
• Role-based access controls
• Ongoing security monitoring

Cybersecurity works best when multiple layers of protection are combined.

FAQs

What is a data breach?

A data breach occurs when personal information is lost, accessed, disclosed or altered without authorisation.

Does every data breach need to be reported?

No. Under Australia’s Notifiable Data Breaches scheme, only eligible data breaches that are likely to result in serious harm must be notified to the OAIC and affected individuals. Each incident should be assessed on its own circumstances.

How quickly should a clinic respond to a data breach?

Immediately. The first priority is to contain the incident, protect systems and begin assessing what has occurred.

What is the most common cause of data breaches?

Common causes include phishing emails, stolen credentials, human error, ransomware, lost devices and accidental disclosure of information.

Can Medic Cloud assist after a data breach?

Yes. Medic Cloud provides healthcare-focused cybersecurity, incident response assistance, backup solutions, disaster recovery planning and ongoing IT support to help clinics reduce risk and recover more effectively.
