What is the Essential Eight?
The Australian Cyber Security Centre (ACSC) created a set of cyber security tactics known as the Essential Eight. It was initially created for the government and larger organisations, but because it emphasises doable, affordable measures to protect against the most prevalent cyberthreats, it is now strongly advised for small and medium-sized enterprises.
With ransomware, phishing scams, and data breaches on the rise in 2025, the Essential Eight offers a methodical, simple-to-follow strategy for companies looking to improve cyber resilience without going over budget.
Why the Essential Eight Matters for Small Businesses
Cybercriminals are increasingly targeting small businesses. Many are open to attacks because they lack specialised IT teams. Putting the Essential Eight into practice aids:
- Reduce the risk of ransomware attacks
- Protect sensitive customer and financial data
- Limit the damage if an incident occurs
- Provide a clear, government-backed framework for cyber security maturity
The Eight Strategies Explained
Here’s what the Essential Eight looks like in practice for small businesses in 2025:
1. Application Control
Your devices should only run trusted apps. This aids in stopping harmful software before it has a chance to do damage.
2. Patch Applications
Outdated apps are exploited by cybercriminals. Frequent updates, also known as patching, fix security flaws in office software, PDFs, and web browsers.
3. Configure Microsoft Office Macro Settings
Macros can automate tasks, but they’re also a common malware delivery method. Disabling or restricting macros reduces risk.
4. User Application Hardening
Block Flash, ads, and untrusted Java content. Criminals often use these weaknesses to launch attacks.
5. Restrict Administrative Privileges
For routine tasks, employees do not require administrator rights. To lessen the harm caused by compromised or stolen accounts, restrict administrator access.
6. Patch Operating Systems
Like applications, operating systems must be kept up-to-date. Unsupported systems (e.g., old versions of Windows) are prime hacker targets.
7. Multi-Factor Authentication (MFA)
Require more than just a password for logins. MFA adds a strong barrier against account takeover.
8. Regular Backups
Make sure you can restore the important data you backup every day. To prevent ransomware from encrypting backups, store them offline.
How Small Businesses Can Get Started
- Start with the basics: Enable MFA, update software, and set up backups — the three most critical defences.
- Work towards Maturity Level One: The ACSC recommends businesses aim for at least Level One, meaning your protections are proactive rather than reactive.
- Get expert help: If you don’t have in-house IT staff, work with a cyber security partner like ARANKISH to implement and monitor the Essential Eight effectively.
