The Essential 8: A Practical Guide for SMBs to Strengthen Cyber Security
Safeguarding the data and operations of your business has never been a more critical concern, no matter your size. For small and medium-sized businesses (SMBs) in Australia, the greater challenge lies in the frequency and sophistication of attacks targeting perceived vulnerabilities. The Australian Cyber Security Centre (ACSC) has developed the Essential Eight cyber security strategies to help organisations, especially SMBs, hold a better defensive stance against these evolving threats.
However, despite these best practices, recent data from The Commonwealth Cyber Security Posture in 2024 highlights ongoing challenges. In 2024, only 15 percent of government entities reached overall Maturity Level 2 across the Essential Eight strategies, a decrease from 25 percent in 2023. This underscores the pressing need for Australian SMBs to prioritise these proven strategies and reduce their exposure to cyber risks.
From application control to daily backups, our most recent blog covers the complete suite of Essential Eight mitigation strategies, highlighting why each is crucial and how they bolster your overall security stance. For businesses seeking a guided approach, Simple Biz is equipped to help implement each of these measures effectively.

What Is the Essential Eight in Cyber Security?
A set of eight strategies forms the ACSC’s cohesive set of cyber protections, known as The Essential Eight. This framework aims to assist organisations in safeguarding against multifarious cyber threats. These strategies are focused on mitigating the delivery and execution of malware, controlling the scale of cyber security incidents, and enhancing the security posture. The framework makes it markedly challenging for attackers to breach systems.

Why is the Essential Eight important for Australian SMBs?
The Essential Eight provides a framework to help SMBs build effective cyber security protections. While Maturity Level One is a starting point, recent data shows that reaching Maturity Level Two is increasingly important. Level Two helps SMBs move beyond basic compliance by actively applying and maintaining security controls. It significantly improves resilience and reduces the risk and impact of cyber incidents.

Breaking Down the Essential Eight Strategies
Here’s a closer look at each of the Essential Eight strategies and how they can fortify your business’s cyber security posture:
- Application Control: Restricting the execution of unapproved applications reduces the risk of malicious software compromising systems. Implementing application control ensures that only trusted applications are allowed to run.
- Patch Applications: Regular application updates address known vulnerabilities, preventing attackers from exploiting outdated software. Timely patching is crucial for maintaining security.
- Configure Microsoft Office Macro Settings: Properly configuring macro settings is essential to reduce the risk of macro-based malware infections. Disabling unnecessary macros and only allowing vetted macros reduces the risk of macro-based malware infections.
- User Application Hardening: Securing applications by disabling unnecessary features and functionalities minimises potential attack vectors. Hardening applications strengthens overall system security.
- Restrict Administrative Privileges: Limiting administrative access to only those who require it reduces the potential impact of compromised accounts. Implementing the principle of least privilege enhances security.
- Patch Operating Systems: Keeping operating systems up to date ensures that known vulnerabilities are addressed, reducing the risk of exploitation. Regular OS patching is a fundamental security practice.
- Multi-Factor Authentication: Implementing Multi-Factor Authentication (MFA) adds an extra layer of security, making it more difficult for attackers to gain unauthorised access to systems and data. MFA is a critical component of secure authentication.
- Regular Backups: Regular backups of essential data ensure that information can be restored during data loss or a cyber incident. Secure and tested backups are vital for business continuity.
Implementing these measures in a coordinated and well-managed way can be challenging. Simple Biz simplifies this process with a Total Security service offering that aligns directly with the Essential Eight strategies.

How can small businesses implement the Essential 8?
Small businesses can implement the Essential Eight by assessing their security posture, developing a practical plan, engaging staff in security awareness, monitoring progress, and seeking expert guidance. These steps strengthen defences and ensure alignment with proven cyber security practices.
These are five practical tips to help strengthen your business:
- Assess Current Security Posture: Evaluate existing security measures to identify gaps and areas for improvement.
- Develop a Plan: Create a roadmap for implementing the Essential Eight strategies, prioritising them based on risk and resources.
- Engage Staff: Educate employees about cyber security best practices and their role in maintaining security.
- Monitor and Review: Regularly assess the effectiveness of implemented strategies and make necessary adjustments.
- Seek Expert Assistance: Consider partnering with cyber security professionals to guide implementation and provide ongoing support.
