As EOFY approaches, South Australian small businesses are busy wrapping up accounts, chasing invoices, and preparing for the new financial year. But there’s one critical area that’s easy to overlook: Cybersecurity!

Tax time is a great opportunity for scammers to target busy owners with fake invoices, phishing emails, and ransomware. 

For small teams in retail, hospitality, or services, one breach can mean lost data, downtime, thousands in costs and quite possibly their entire business. 

The good news? You don’t need a big IT budget to make your business much safer. Here are 10 practical tasks you can tackle in the next couple of weeks to keep on track and in control of your risks.

10 Practical EOFY Cybersecurity Tasks

1. Update All Devices and Software

Ensure your computers, phones, tablets, routers and business software are fully updated as software updates often contain important security fixes.

2. Remove Old User Accounts

Review staff access to your systems, email accounts and applications. Identify and remove access for former employees, contractors or suppliers who no longer need it.

3. Turn On Multi-Factor Authentication (MFA)

Enable MFA on email, banking, accounting software and cloud systems, providing you with one of the simplest and most effective security measures available.

4. Review Your Passwords

Avoid reusing passwords across systems. Use strong passwords and consider a password manager for your business.

5. Test Your Backups

Confirm your important business data is being backed up properly and that backups can actually be restored if needed.

6. Train Staff on Scam Emails

Phishing emails remain one of the biggest risks for small businesses. Remind staff to be cautious with unexpected invoices, payment changes and links.

7. Audit Business Devices

Make a list of all devices connected to your business. Remove unused devices and ensure work devices are protected with passwords and screen locks.

8. Review Payment and Invoice Procedures

Introduce a simple verification process before changing bank account details or making unusual payments.

9. Review Customer Data Storage

Ensure your customer/​client data is securely stored and with appropriate access controls in place. Check where your data is held and delete information that is no longer required or covered by retention rules.

10. Create a Simple Incident Plan

If your systems were hacked tomorrow, what would you do first? Even a one-page response plan can save you valuable time during an incident.

Quick Wins You Can Do This Week

  • Turn on MFA
