Cyber attacks are on the rise, with criminals constantly searching for vulnerabilities in business IT systems and exploiting human error.
If you think your business is too small to be targeted, think again: Recent research from the Actuaries Institute shows that 44% of small business owners are not being proactive about cyber security because they believe it’s too complex to tackle, yet worryingly, 63% of small and medium enterprises (SMEs) have experienced a cyber security incident.
This article explains what you need to know to protect your business.
The real cost of cybercrime in Australia
Data from the Annual Cyber Threat Report 2023-2024 tells a concerning story:
- A cybercrime is reported every 6 minutes (that’s over 87,400 reports annually)
- The average cost per cybercrime for small businesses is $49,600, $62,800 for medium businesses, and $63,600 for large businesses.
- The top 3 self-reported cybercrime types for businesses are email compromise (20%), online banking fraud (13%) and business email compromise with financial loss (13%).
Why cyber security is everyone’s business
Cyber security is more than an IT issue – it’s a business risk that affects every level of your organisation. All organisational leaders need to be well informed about cyber security risks and mitigation – relying on the IT department or an outsourced IT provider is no longer enough.
And while technical solutions are important, human error remains a significant factor in security breaches, whether through:
- Stolen credentials
- Clicking on phishing emails
- Accidental data exposure.
So, cyber security is everyone’s business, and staff at all levels need to be aware and informed.
Plenty of resources are available for businesses, some of which we’ll explore below.
Common cyber threats to watch out for
1. Phishing scams
These are fake emails or messages trying to trick you into:
- sharing passwords
- sharing confidential details
- clicking malicious links.
They often look legitimate but contain suspicious links or urgent requests.
2. Malware
Malware is malicious software designed to cause harm that can infect your devices and
- delete or corrupt your files
- stop your devices from working properly
- give others access to your private data.
3. Ransomware
A particularly nasty type of malware that locks up your files and demands payment to release them.
Practical steps to protect your business
Cyber security for small businesses
1. Use software tools:
- Set up automatic updates: Regular software updates will help you close any security gaps.
- Back up your data daily: This ensures you can recover your data in the event of a cyberattack.
- Use multi-factor authentication (MFA): To prevent unauthorised access to systems and data.
2. Focus on people and procedures:
- Control access levels: Make sure you know who in your business has access to what, and limit data access to necessary people only.
- Use strong passwords: Choose a password manager app for your business (like Keeper, LastPass, or 1Password) and use it to generate and securely store strong passwords.
- Train your team: See the small business resources below for training opportunities to share with your employees.
Cyber security for medium and large businesses
Consider implementing the Essential Eight framework from the Australian Cyber Security Centre. Although this may require technical support, implementing these essential mitigation strategies will make your business more robust against cyber attacks.
The essential eight mitigation strategies are:
- Application control: Control which applications can run on your systems
- Patch applications: Keep all software up to date
- Configure Microsoft Office macro settings: Prevent macros from running automatically and potentially executing malicious code.
- User application hardening: Set up protective browser and email settings
- Restrict administrative privileges: Prevent unauthorised changes to systems and data.
- Patch operating systems: Update operating systems with the latest security patches to prevent known vulnerabilities from being exploited.
- Use multi-factor authentication (MFA): To prevent unauthorised access to systems and data.
- Back up your data daily: This ensures you can recover your data in the event of a cyberattack.

Cyber security for large organisations
Larger organisations are going to require more in-depth cyber security controls and may consider applying the following:
- ISO 27001: International standards focused on information security.
- Information Security Manual: An Australian-based cyber security framework that organisations can apply, using their risk management framework, to protect their information and systems.
