Cyber Security Checklistfor Small Businesses
Cyber threats aren't just for big corporations. In fact, 43% of cyberattacks in Australia hit small businesses. A single mistake — a weak password, a lost laptop, or a phishing email — can cost you tens of thousands.
Is your business secure enough to protect customer data?
This Cyber Security Checklist covers the essential, practical steps every small business in Melbourne & Sydney should have in place.
Tick off what you already do
If you're missing items, don't panic — we can help. Most cyberattacks on small businesses are cheap to prevent but expensive to recover from.
The Checklist
Eight essential security measures that will protect your business from the most common cyber threats.
1. Strong Access Controls
Secure authentication and account management
Why it matters: Most breaches start with a weak or reused password. MFA stops 99% of account hacks.
2. Email & Phishing Protection
Protect against email-based attacks
Why it matters: 67% of breaches in Australia come from human error — mostly phishing.
3. Device Security
Secure laptops, phones, and mobile devices
Why it matters: A stolen laptop with unencrypted data is a privacy breach under law.
4. Secure Networks
Protect your business network infrastructure
Why it matters: Hackers often exploit poorly secured Wi-Fi or default router settings.
5. Data Backups & Recovery
Ensure business continuity and data protection
Why it matters: Ransomware can lock you out — backups are your lifeline.
6. Software & Updates
Keep systems patched and secure
Why it matters: Most cyberattacks exploit outdated software.
7. Staff Training & Policies
Build a security-aware culture
Why it matters: Technology alone won't save you — people are your first line of defence.
8. Incident Response Plan
Be prepared for security incidents
Why it matters: A clear plan avoids panic and cuts downtime if something goes wrong.
If you're missing items, you're exposed
