The Australian Cyber Security Centre developed the Essential Eight as mitigation strategies that make it harder for attackers to compromise systems. It is not a one-off product or a simple checklist. Each strategy involves technology, process and evidence, and the maturity model describes increasing levels of implementation.
The eight strategies in plain language
- Application control: limit which applications can run.
- Patch applications: address security weaknesses in software promptly.
- Configure Microsoft Office macros: restrict macros that could deliver malicious code.
- User application hardening: reduce risky browser, PDF and application features.
- Restrict administrative privileges: keep powerful access limited and controlled.
- Patch operating systems: keep operating systems supported and updated.
- Multi-factor authentication: require more than a password for important access.
- Regular backups: protect and test recovery of important data and systems.
What maturity means
Maturity levels are defined sets of requirements, not a percentage score. A business should avoid claiming a maturity level based on a few controls or a tool report alone. Current-state assessment, evidence and the dependencies between controls all matter.
A practical starting process
- Identify important systems, data and business obligations.
- Map the current environment and collect evidence.
- Assess gaps against the relevant target maturity level.
- Prioritise high-impact foundations and dependencies.
- Assign owners, budgets and realistic completion dates.
- Review controls as the environment changes.
Connect the framework to daily IT
Patching, administrator access, MFA and backups depend on consistent day-to-day administration. That makes Essential Eight improvement closely related to managed IT services, Microsoft 365 support and broader cyber security services.
