Cyberattacks on Australian small businesses surged by 14% last year, with the average cost of a data breach reaching $4.03 million (IBM, 2024). Yet most SMEs still operate with minimal security controls. Here are 8 essential protections every business should have in place.
1. Multi-Factor Authentication (MFA)
Enable MFA on every business account: email, banking, cloud storage, and accounting software. MFA blocks over 99% of automated account compromise attacks.
2. Keep Software Updated
Enable automatic updates for operating systems, browsers, and applications. Most ransomware exploits vulnerabilities that have already been patched — delayed updates are your biggest risk.
3. Regular Encrypted Backups
Follow the 3-2-1 backup rule: 3 copies of data, on 2 different media, with 1 offsite (cloud). Test your backups quarterly by actually restoring from them.
4. Staff Security Awareness Training
Phishing attacks account for 90% of data breaches. Regular training that includes simulated phishing tests dramatically reduces click-through rates on malicious emails.
5. Password Manager
Deploy a business password manager (1Password Teams, Bitwarden Business) to eliminate password reuse and ensure every account has a unique, strong credential.
6. Cyber Liability Insurance
Cyber insurance covers breach response costs, legal liability, and business interruption. For Australian SMEs handling client data, this is increasingly a client contractual requirement.
7. Network Segmentation
Separate your guest Wi-Fi from your business network. Use VLANs to isolate IoT devices (printers, cameras) from your core business systems.
8. Incident Response Plan
Document a step-by-step plan for what to do when (not if) a breach occurs: who to call, how to isolate affected systems, and your obligations under the Notifiable Data Breaches (NDB) scheme to notify the OAIC and affected customers.
