How to Strengthen Your Cybersecurity Using the Essential 8 Framework
If you’ve ever tried patching the roof during a storm, you’ll understand the value of preparation. The same principle applies to cybersecurity. Waiting for a cyberattack before putting controls in place is like fixing leaks when it’s already bucketing down. That’s where the Essential Eight Framework comes in: a proactive, structured approach to protect your business from the most common types of cyber threats.
What Is the Essential Eight?
Developed by the Australian Cyber Security Centre (ACSC), the Essential Eight is a set of baseline strategies designed to help businesses mitigate cybersecurity incidents. Think of it as a toolkit tailored for Aussie organisations to keep systems secure and operations humming along.
The framework is broken into eight key mitigation strategies:
- Application control
- Patch applications
- Configure Microsoft Office macro settings
- User application hardening
- Restrict administrative privileges
- Patch operating systems
- Multi-factor authentication (MFA)
- Daily backups
Let’s Break It Down
1. Application Control
This one’s about making sure only approved software runs in your environment. It’s like having a security guard at the door vetting who gets in. Blocking unauthorised applications reduces the risk of malware sneaking its way in.
We’ve covered this in more depth in our post Mastering Application Control.
2. Patch Applications and Operating Systems
Ever had a mate tell you to update your phone, and you ignore it until something breaks? Same goes for business systems. Unpatched software is one of the easiest ways for attackers to get in. Regular patching plugs those gaps before they’re exploited. It’s boring, but it works.
3. Configure Microsoft Office Macro Settings
Macros can automate tasks, but they can also be used to deliver malware. Disabling them for unfamiliar documents or running them in a controlled mode adds a layer of safety without compromising productivity.
4. User Application Hardening
This involves reducing the attack surface of your apps. Disable unnecessary features like Flash (remember that?), ads in browsers, or Java content unless absolutely needed. It’s like childproofing your home – you keep the essentials but remove the risks.
5. Restrict Admin Privileges
Not everyone needs the keys to the castle. Limiting admin access to only those who really need it, and only when they need it, reduces the damage someone can do if their account is compromised.
6. Multi-Factor Authentication (MFA)
Passwords alone just don’t cut it anymore. MFA adds another layer – something you know (password) plus something you have (like your phone). It’s simple and effective, and something we talked about in Tech Talk: What is MFA?
7. Daily Backups
Backups are your safety net. If all else fails, you can restore your systems and data. But make sure you test them – a backup that doesn’t restore properly is about as useful as a chocolate teapot. For more on this, check out 3 Catastrophic Consequences of Data Loss.
How to Get Started
Start by assessing your current security posture. You don’t need to implement all eight strategies at once, but even adopting a few will significantly reduce your risk. The ACSC provides maturity models you can use to identify gaps and track progress.
At Gray Area Consulting, we help businesses apply the Essential Eight in a way that suits their size, industry and budget. Whether you’re just starting or looking to mature your security posture, we’re here to lend a hand.
Why It Matters
Cyber threats aren’t just a problem for big corporations. Small and medium businesses are prime targets because attackers know they often don’t have the same resources or defences. Implementing the Essential Eight gives you a fighting chance and helps you stay compliant with industry standards and expectations.
