Essential Eight Self-Assessment

The Essential Eight is the Australian government's recommended baseline for cyber defence. Developed by the Australian Cyber Security Centre (ACSC), it provides eight mitigation strategies that, when implemented effectively, make it much harder for attackers to compromise your systems.

Why the Essential Eight matters for small businesses

While the Essential Eight was originally developed for government agencies, the ACSC now recommends it for all Australian organisations regardless of size. Small businesses are particularly vulnerable to cyber attacks because they often lack dedicated IT security staff and have limited budgets for security tools. The Essential Eight provides a practical, prioritised framework that helps small businesses focus their security efforts where they will have the most impact.

The eight strategies explained

• Application Control - Prevents unapproved programs from running on your systems. This stops malware and unauthorised software from executing even if it reaches your devices.
• Patch Applications - Keeps third-party software like browsers, PDF readers, and Office up to date. Unpatched applications are one of the most common entry points for attackers.
• Configure Microsoft Office Macros - Restricts macros, which are commonly used to deliver malware via email attachments. Only trusted macros from approved sources should be allowed to run.
• User Application Hardening - Disables unnecessary features in web browsers and other applications, reducing the attack surface available to attackers.
• Restrict Admin Privileges - Limits who has administrative access to systems. If an attacker compromises a standard user account, the damage is contained.
• Patch Operating Systems - Keeps Windows, macOS, and other operating systems up to date with security patches. Like application patching, this closes known vulnerabilities.
• Multi-Factor Authentication - Requires a second form of verification beyond passwords. Even if a password is stolen, the attacker cannot log in without the second factor.
• Regular Backups - Maintains tested copies of critical data so you can recover from ransomware, hardware failure, or accidental deletion. Backups should be protected from ransomware with immutable snapshots.

Getting started

If your self-assessment revealed gaps, the good news is that most Essential Eight strategies can be implemented incrementally. Start with the highest-impact, lowest-effort items: enabling MFA on all accounts, setting up automated patching, and ensuring you have tested backups. From there, work toward application control, macro restrictions, and privilege management with the help of an experienced IT partner.
