Most information security guidance is written for IT departments, not for the person actually running a clinic. The Australian Digital Health Agency's foundational guide for small healthcare businesses is the exception — it's five short, practical habits, no technical background required. Here they are, in plain language for an Australian specialist clinic.
1. Privacy — know your obligations
Every health service provider in Australia, regardless of size, is bound by the Privacy Act 1988 to take "reasonable steps" to protect the personal and health information it holds. What counts as reasonable isn't left to guesswork — the Office of the Australian Information Commissioner (OAIC) publishes guidance on exactly this. If your practice ever has a suspected data breach, notification to affected patients and the OAIC is mandatory, not optional — so it's worth knowing your obligations before you need them, not during an incident.
2. Passphrases — longer beats cleverer
A password made of four or more random, unrelated words is both easier for a person to remember and harder for a machine to crack than a shorter password stuffed with substitutions ("P@ssw0rd!" is not as clever as it feels). Aim for at least 12–14 characters, mix in numbers and symbols, and never reuse the same passphrase across multiple systems — one compromised login shouldn't be able to unlock everything else.
Where remembering unique passphrases for every system gets impractical, a reputable password manager solves the problem — staff only need to remember one very strong master passphrase, plus their computer login. Turn on multi-factor authentication everywhere it's offered; it's the single biggest upgrade available for the effort involved.
3. Network and device security — patch, filter, isolate
Unpatched software is one of the most common ways attackers get in — most successful attacks exploit vulnerabilities that already have a fix available, just not yet applied. Set operating systems and applications to update automatically wherever possible, and run antivirus software on every device that touches your network.
Treat any Wi-Fi network your practice doesn't control — cafés, shared buildings, public hotspots — as insecure by default. If staff need to work from one, at minimum it should require a password, and ideally traffic should run through a VPN.
4. Backups — the difference between an incident and a disaster
If ransomware locks up your patient records tomorrow, the only reliable way back is a clean backup taken before the infection. A backup that's still plugged into the same network as the system it's protecting isn't a real backup — it's just another thing ransomware can encrypt.
Keep backups frequent, stored off-site or disconnected from the live network, and actually test that you can restore from them. A backup nobody has ever tried to restore from is a hope, not a plan.
5. Awareness — the habit that catches what technology misses
No firewall or antivirus product catches everything — a meaningful share of successful attacks still start with a staff member clicking a link they shouldn't have. Building a "stop and think before you click" reflex across the practice, and making it normal to ask "is this what it looks like?" before acting on an email or message, closes a gap no software can.
It also means knowing when to bring in outside help. If you're already paying for an IT provider, make sure you actually understand what security measures they provide — not just what's in the invoice.
A few extra habits worth adopting
Beyond the five basics, a handful of small configuration choices go a long way:
- Restrict administrator-level access to only the staff who genuinely need it, and don't use admin accounts for everyday email and browsing.
- Encrypt the disk on any computer that stores patient information, in case it's lost or stolen.
- Change every default password — especially on your router/modem — to a long passphrase.
- If your practice offers Wi-Fi, use WPA2 (or newer) with a long passphrase, not an open network.
- Only install the software your practice actually needs. Fewer applications means fewer things that can go wrong and fewer things to keep patched.
Where to start
None of this requires a security budget or a technical background — just five habits, applied consistently. If you're not sure where your practice currently sits against these basics, that's exactly what a Clinic IT Health Check is for.
