Cyber incidents in healthcare are no longer rare events. They create a tanglible and immediate risk for patient care, business operations, and compliance outcomes.
Across Australia, clinics, medical practices, allied health providers, and aged care organisations are attractive targets because attackers know that service disruption creates pressure fast. When systems go down, the impact moves well beyond IT. Appointments are missed, teams fall back to manual workarounds, and leadership is forced to make high-stakes decisions quickly.
That is why prevention alone is not enough. Firewalls, endpoint protection, email security, and staff awareness training all matter, but no environment is immune to compromise. A strong cybersecurity posture also requires a practical cyber incident response plan that people can follow under pressure.
In healthcare and aged care, this matters even more. A cyber incident quickly becomes a patient safety issue, a reputational issue, and a governance issue at the same time. Response planning needs to support operational continuity, regulatory obligations, and fast decision-making.
This article explains how to build incident response playbooks that are simple, useful, and aligned with Australian healthcare cybersecurity expectations.
A cyber incident response plan is a documented set of actions that helps an organisation detect, contain, respond to, and recover from a cyber attack.
In practical terms, it tells the business what to do when a serious event occurs. It clarifies who makes decisions, who communicates with staff and stakeholders, how systems are isolated, and how services continue while the issue is being contained.
A good plan should answer simple questions clearly:
If those answers are not clear before an incident, they will not become clear during one!
Healthcare and aged care environments rely on systems that support critical day-to-day operations. That includes clinical applications, medication records, rostering, communication platforms, file storage, finance systems, and connected devices.
When a ransomware attack or email compromise hits, the business often has very little time to respond. Teams need to decide whether systems stay online, whether manual processes can carry the load, and whether external reporting thresholds have been triggered.
This is where a generic incident response document often falls short. Healthcare and aged care providers need scenario-specific playbooks that reflect the way the organisation actually works.
The most common place to start is with:
Starting with these scenarios helps build a response capability around the threats most likely to cause real disruption.
A useful playbook should be short, action-oriented, and easy to use in a stressful situation. It should guide the first 30 to 60 minutes clearly, while linking to deeper technical procedures where needed.
Define what activates the playbook.
For ransomware, this could include:
For email compromise, triggers may include:
Document the first actions that reduce impact.
This may include:
These actions need to be assigned to named roles, not vague teams. Clear ownership reduces delay.
Cyber response in healthcare is not just about technology. It is also about continuity of care and continuity of service.
Your playbook should define:
This section needs to be written in plain language so operational leaders can use it without the need for technical interpretation.
Communication must be clear, deliberate and timely during a cyber incident.
The playbook should outline:
Pre-approved messaging templates save time and reduce avoidable confusion.
Every playbook should define when to escalate and who to contact.
This may include:
In Australia, this process needs to consider obligations that involve the ACSC, the OAIC under the Notifiable Data Breaches scheme, and sector-specific regulators where relevant.
A written plan is only the starting point. It needs to be tested regularly to prove that it works in the real world.
Tabletop exercises are the best place to start. Run them at least twice a year using realistic scenarios that reflect your environment.
Good examples include:
Bring the right people into the exercise. That usually includes operations, leadership, finance, communications, and IT support.
Work through simple questions:
The purpose of testing is not to prove the plan is perfect. The purpose is to identify gaps while the cost of fixing them is still low.
Incident response and recovery planning should work together.
At least once a year, test whether critical systems can be restored from backup within the expected timeframe. Validate recovery time objectives against what is actually achievable, not what is assumed.
Also confirm that staff can work through manual or degraded processes if systems remain unavailable for longer than expected. A documented workaround is only useful if teams know where it is and how to use it.
Healthcare and aged care providers should align their incident response planning with recognised Australian guidance and compliance expectations.
The most common reference points are:
This alignment demonstrates due diligence and supports stronger governance, insurer engagement, and compliance readiness.
A practical cyber incident response capability is more than a document stored in SharePoint. It requires tested processes, working backups, clear ownership, and systems configured to support rapid containment and recovery.
Microsolve works with healthcare and aged care organisations to strengthen their capability through managed cybersecurity, Microsoft 365 security, backup and recovery planning, cloud infrastructure support, and practical incident response readiness as a key team member.
The goal is straightforward. When a cyber incident occurs, the business should know what to do next, who is responsible, and how to keep essential services running safely.
