As cyber-attacks and data breaches become more advanced, many businesses across the globe are turning to cyber security frameworks to help them stay ahead. In Australia, the ACSC Essential 8 is one of the most popular – and for good reason. While many businesses understand the basics, few take the time to build upon the fundamentals for more comprehensive security and compliance.
What is the ACSC Essential 8?
The Essential 8 is a cyber security framework developed by the Australian Cyber Security Centre (ACSC) to help businesses protect themselves from threat actors. It identifies eight mitigation strategies designed to prevent and reduce the impact of cyber-attacks. They are categorised into three main objectives.
- Preventing Malware Delivery and Execution
- Limiting the Extent of Cyber Incidents
- Recovering Data and System Availability
Why Essential 8 Compliance Matters
Compliance with this cyber security framework is valuable for several reasons:
- Reduced Risk of Cyber Incidents: Essential 8 strategies significantly mitigate risks such as ransomware attacks, data breaches, and phishing schemes.
- Regulatory and Industry Standards: For Australian businesses, complying with the Essential 8 framework helps ensure alignment with government-mandated cyber security requirements.
- Enhanced Business Resilience: With robust measures in place, businesses can recover more effectively from potential cyber disruptions.
Breaking Down the Essential 8
To achieve compliance, businesses must implement the following strategies:
1. Application Control: Restrict execution of unapproved applications to reduce exposure to malicious software.
2. Patch Applications: Regularly update software to close vulnerabilities.
3. Configure Microsoft Office Macros: Secure macro settings to limit potential exploitation.
4. User Application Hardening: Prevent browser-based threats by disabling Flash, Java, and other risky features.
5. Restrict Administrative Privileges: Limit administrative access to only those who require it, reducing insider and outsider threats.
6. Patch Operating Systems: Ensure all operating systems are up-to-date.
7. Multi-Factor Authentication (MFA): Add an extra layer of security by requiring multiple forms of verification to access accounts.
8. Daily Backups: Regularly back up critical data to support recovery in the event of a cyber-attack.

Building on the Basics of the Essential 8
Cyber threats change regularly. Conduct regular risk assessments to identify vulnerabilities, and adapt strategies to address new challenges.
Even the most advanced cyber security measures can fail if employees are not equipped to recognise threats. Incorporate training on phishing, social engineering attacks, the Essential 8, and secure password practices.
Manual processes can leave room for error. Automating tasks like patch management, backup scheduling, and user monitoring ensures consistency and efficiency.
Leverage available tools to track progress. Regularly review policies, procedures, and technical controls to identify gaps and ensure alignment with the framework.
The Essential 8 cyber security framework is designed to be scalable, so that it can grow with businesses. As IT needs change, it is best to adopt more stringent versions of previously adopted measures. This will ensure that defences remain effective in the long run.
Overcoming Essential 8 Compliance Challenges
Adopting and maintaining the Essential 8 comes with challenges, but these can be overcome with the proper planning.
- Resource Limitations: Small to medium-sized businesses (SMBs) may lack the resources for full compliance. Partnering with managed IT providers can bridge this gap.
- Complex IT Environments: Large organisations with sprawling networks may struggle to implement uniform policies. Establishing clear governance structures and facilitating communication between departments can simplify this process.
- Resistance to Change: Staff or leadership may be reluctant to adopt new protocols. Education and emphasising the cost of inaction can build confidence.
The ROI of Essential 8 Compliance
Beyond minimising risks, the benefits of Essential 8 compliance include:
- Cost Savings: Avoiding data breaches and downtime saves significant financial resources.
- Customer Trust: A secure business instills confidence among clients and partners.
- Operational Continuity: With preventive measures in place, businesses can maintain continuity even during cyber incidents.
