Why the Essential 8 Matters for Australian Businesses

Small to medium businesses (SMBs) remain the most frequent targets of cyber attacks. The Australian Cyber Security Centre (ACSC) developed the Essential 8 to give organisations a clear framework for defending against common threats. Aligning with the Essential 8 reduces risk, builds client trust, and helps ensure compliance with standards such as ISO 27001 and the Australian Privacy Act. This article explains what the Essential 8 are and how your business can implement practical strategies to strengthen its cyber security. Skip ahead: Essential 8-image1

What Is the Essential 8?

The Essential 8 is a set of baseline mitigation strategies designed to make it harder for attackers to compromise your systems. They focus on practical actions across people, systems, and governance.

Mitigation Strategies to Prevent Malware Delivery and Execution

  • 01 Application Control Application Control is a cyber-attack prevention strategy. It involves generating an index of approved applications which are allowed to run in trusted locations on a computer network. In contrast, application deny-listing (also known as blacklisting) is the process of denying certain programs to run. Application Control is a stronger prevention tool as it combats zero-day attacks.
  • 02 Patching Applications Patch Application is the process of installing patches to fix identified vulnerability in software applications. Patches can also provide upgrade of features and extended functionalities. Regular updates can dramatically reduce the risk of cyber-attacks. Find out more.
  • 03 Configure Microsoft Office Macro Settings Configuring Microsoft Office settings can prevent malicious macros installing and running on your computer system. Dangerous macros are often embedded in seamlessly ‘normal’ documents such as Excel or Word files and can be accidentally downloaded via websites or email. Smart configuration of Microsoft Office programs can prevent macros in their tracks. Find out more.
  • 04 User Application Hardening Similar to Application Control, User Application Hardening is the process of deciding what certain applications/programs are allowed to do on a system or network. This is important as applications such as Adobe Flash and Java can sidestep traditional antivirus software to enable malware or exploit kits to be downloaded onto your computer business network. Find out more.

Mitigation Strategies to Limit the Extent of Cyber Security Incidents

  • 05 Restrict Administration Privileges Restricting Administrative Privileges is the practice of only enabling the minimal computer administrative privileges needed by an employee to carry out their daily operational needs. Reducing the number of people who have overarching rights to install programs, run macros and enable applications, reduces the risk that a hacker can access the system. Further, if a system is hacked, it limits the extent of potential damage. Find out more.
  • 06 Patch Operating Systems Patching Operating Systems is a cyber security strategy which can mitigate the risk of cyber-attacks, as well as reduces potential damage. Like applications, the operating system needs to be updated regularly to fix known vulnerabilities. Without patching, hackers can leverage weaknesses in the system. Find out more.
  • 07 Multi-factor Authentication Multi-Factor Authentication is the strategy of establishing multiple sign-in requirements for users to log in to devices and programs. This increases the difficulty of a hacker accessing a user’s system via a vulnerability. Common Multi-Factor Authentication processes involve the user undertaking a standard sign in, and then confirming a code which is sent to an email or mobile phone to verify their identity. Find out more.
  • 08 Daily Backups A Daily Backup offers a last resort, ‘if all else fails’ solution for recovering stolen, hacked, damaged or lost data. The ACSC Essential 8 strategy recommends all backups are stored for at least 3 months in a secure online or offline location that is not rewritable and non-erasable. Hopefully, companies never need to use their backups, but it is good to know they are there just in case. Find out more.

What’s The Real Risk of Falling Short?

According to the ACSC Annual Cyber Threat Report, one cyber crime is reported every six minutes in Australia. Additionally, the latest Australian Government Annual Cyber Threat Report 2024–25 reported that: The Average self-reported cost of cybercrime per report for businesses rose by 50% overall ($80,850)
    • small business: $56,600 (up 14%)
    • medium business: $97,200 (up 55%)
    • large business: $202,700 (up 219%)
Many of these attacks exploit simple weaknesses like outdated software or stolen passwords. The Essential 8 provides guidelines to protect against these common threats, and it’s recognised as starting framework by both government and industry.

Most Common Weak Points for Businesses

  • Unpatched systems: Cyber criminals often exploit vulnerabilities that have known fixes.
  • Weak passwords: Reused or shared passwords are a major risk.
  • Inconsistent backups: Backups that fail or aren’t tested leave data unrecoverable.
  • Admin misuse: Staff with unnecessary access increase exposure if their accounts are compromised.

Building a Culture Around Cyber Hygiene

Technology alone isn’t enough. The Essential 8 works best when combined with strong governance and staff awareness. Regular training, clear access policies, and scheduled audits ensure that controls remain effective long term. A good practice is to include Essential 8 reviews in quarterly IT or risk meetings. Aligning these strategies with your Information Security Management System (ISMS) or business continuity planning helps embed them into your organisation’s routine. ACSC Essential 8 Framework

Things Your Business Can Do Today to Align with the Essential 8

For SME owners in Australia, adopting the ACSC’s Essential 8 is an achievable way to enhance cyber security. Here are practical steps you can take right now to strengthen your defences:
  • Run a quick cyber audit: Start with a short internal review of your systems, passwords, and data protection measures. Document what’s already in place and what’s missing. Use this as your baseline to track improvement over time.
  • Turn on automatic updates: Enable automatic patching on computers, servers, and mobile devices. This includes your browser, antivirus software, and any cloud-based tools. Check monthly that updates are actually running successfully.
  • Set up MFA for key systems: Begin with your email and accounting platforms, then extend MFA to cloud storage and internal systems. For convenience, use authentication apps like Microsoft Authenticator or Google Authenticator instead of relying on SMS codes.
  • Review who has admin rights: Conduct a quarterly audit of user permissions. Remove access for former employees or contractors and separate admin accounts from day-to-day user accounts. This reduces the potential for human error and insider threats.
  • Create an application allow-list: List all the programs your business needs to operate and restrict everything else. You can use endpoint protection software to automate this process. This stops unauthorised software from running, protecting against ransomware and shadow IT risks.
  • Back up and test weekly: Perform regular automated backups of files, emails, and systems. Store one copy offline or in immutable cloud storage that can’t be overwritten. Test a full restore at least once every three months to confirm your backup works as expected.
  • Run a phishing test: Simulate phishing attacks and identify where staff need more training. Discuss the results openly and share examples of real scams to build awareness without blame.
  • Update your cyber policies: Review your acceptable use, password, and remote work policies. Ensure they include details about MFA, data sharing, and personal device use. Store them in an easily accessible place and require staff to acknowledge they’ve read them.
  • Harden devices: Disable outdated or unused features like Flash, macros, and remote desktop access. Encrypt laptops and mobile devices, and apply screen-lock timeouts to all devices used for work.
  • Schedule quarterly reviews: Put cyber security on your business calendar. Each quarter, review your Essential 8 progress, discuss incidents or near misses, and set goals for the next 90 days. Consistent oversight helps keep alignment active and effective.
Implementing even a few of these strategies puts your business on the path to stronger, more reliable cyber protection.
