What are the cybersecurity requirements under Australia’s Essential Eight?
TL;DR: The Essential Eight is a prioritized set of mitigation strategies from the Australian government that helps organizations defend against cyber threats—mapping directly to core cybersecurity domains like patching, access control, and secure configuration.
According to the 6clicks expert guide Mastering the Cybersecurity Domain in 2025, the Essential Eight (E8) is a practical, risk-driven framework created by the Australian Cyber Security Centre (ACSC). It provides guidance on implementing foundational cybersecurity controls that can prevent up to 85% of targeted attacks.
Unlike broader frameworks like ISO 27001 or NIST CSF, the Essential Eight is designed to be prescriptive and tactical, particularly for government and critical infrastructure sectors. It is widely used across both public and private organizations in Australia.
The eight mitigation strategies:
-
Application control
Prevent unauthorized executables from running (whitelisting). -
Patch applications
Fix software vulnerabilities quickly—especially for internet-facing systems. -
Configure Microsoft Office macro settings
Block malicious macros that can launch payloads. -
User application hardening
Disable features like Flash, ads, and Java not required for business. -
Restrict administrative privileges
Enforce least privilege and tightly control elevated access. -
Patch operating systems
Update OS regularly to close known security holes. -
Multi-factor authentication (MFA)
Add an extra layer of protection for logins and access. -
Regular backups
Ensure secure and restorable backups are available to recover from incidents.
How Essential Eight maps to core domains
-
Asset security – via patching and application control
-
IAM – via MFA and admin restrictions
-
Security operations – through monitoring and response
-
Software development security – indirectly through hardening and secure configuration
-
Risk management – via tiered maturity model (Levels 1–3)
Organizations are expected to assess themselves against these maturity levels to guide improvements and demonstrate resilience.
