Essential 8 Overview 

Since 2010 the Australian government has disseminated information to improve cybersecurity and better protect our nation’s digital assets. The “Essential-8” is the latest iteration that began with the Defence Signals Directorate’s (DSD now ASD) “Top 35” mitigation strategies. Over the ensuing decade little has changed with poor patching still posing the most insidious risk to organisations. The ASD have distilled more than a decade of analysis into the Essential-8 analysis that will help organisations of every size validate their existing safeguards and prioritise their security requirements  based on cold, hard data from an independent source.

  • Delegate access across the Enterprise
  • Monitor and record sessions for analysis or forensic auditing
  • Enforce least privilege compliance across the Enterprise
 

Flexera Patch Management

Software patching still poses one of the gravest security threats to organisations. Flexera’s Software Vulnerability Manager’s “Vendor Patch Management” solution identifies, prioritises and remediates gaps in application and operating system patching. Flexera’s Secunia Research division provides Enterprise class security research that captures data from software vendors and enables IT administrators to keep abreast of patching threats. 

Snapshot

  • Leverage the capabilities of a dedicated application designed to ensure patches are applied in a timely manner
  • Limit the risk of attack and breach using published vulnerabilities as an attack vector
  • Prioritise patching based on business risk and not chronology
  • Mitigate a risk identified by Australia’s DSD as one of the most virulent and avoidable IT security threats faced by system administrators

Sécurité Partner – Airlock Digital

2. Patch Applications

Patch Applications e.g. Flash, web browsers, Microsoft Office, Java and PDF viewers. Patch/mitigate computers with ‘extreme risk’ vulnerabilities within 48 hours. Use the latest version of applications.

Sécurité Partner – Flexera

3. Configure Microsoft Office macro settings

Configure Microsoft Office macro settings to block macros from the internet, and only allow vetted macros either in ‘trusted locations’ with limited write access or digitally signed with a trusted certificate.

4. User Application hardening

User application hardening. Configure web browsers to block Flash (ideally uninstall it), ads and Java on the internet. Disable unneeded features in Microsoft Office (e.g. OLE), web browsers and PDF viewers

Secure Smarter, Operate Better

Essential 8 : Strengthen Your Cyber Defences with the Essential Eight

A proven framework from the Australian Signals Directorate to reduce your risk of cyber threats.

Developed by the Australian Signals Directorate (ASD), the Essential Eight is a set of prioritised mitigation strategies designed to help organisations strengthen their cybersecurity posture against a wide range of threats. These strategies focus on protecting internet-connected IT networks and represent the most effective measures from ASD’s broader Strategies to Mitigate Cyber Security Incidents framework.


While the Essential Eight is specifically tailored for IT environments, its underlying principles can also inform cybersecurity approaches in enterprise mobility and operational technology networks—though different or additional measures may be required in those contexts.
To guide implementation, ASD has released the Essential Eight Maturity Model, first published in 2017 and regularly updated. This model reflects ASD’s deep expertise in cyber threat intelligence, incident response, penetration testing, and hands-on support for organisations deploying these strategies.

Why the Essential 8 Matters

Cyber threats continue to grow in sophistication, frequency, and impact—making it critical for organisations to adopt proactive security measures. The Essential Eight offers a proven, cost-effective foundation to:

  • Significantly reduce the likelihood and impact of common cyberattacks
  • Strengthen organisational resilience across user, system, and data layers
  • Align with government and industry-recognised cybersecurity best practices
  • Support compliance with internal policies or external regulatory frameworks


By implementing the Essential Eight, organisations can measurably reduce their exposure to ransomware, malware, unauthorised access, and data breaches.

The Eight Strategies
at a Glance

Patch
Applications

Keep third-party applications (like browsers, PDF readers, and office software) up to date to close known security vulnerabilities that attackers commonly exploit.

Patch Operating
Systems

Ensure operating systems are regularly updated with the latest security patches to protect against critical threats and system-level exploits.

Multi-Factor Authentication (MFA)

Add an extra layer of protection by requiring users to verify their identity using more than one method (e.g., password + mobile app code).

Administrative Privileges

Limit admin rights to only those who truly need them, reducing the risk of attackers gaining full control of systems through compromised accounts.

Application
Control

Only allow approved applications to run, blocking malicious software or unapproved tools that could be used for attacks.

Restrict Microsoft Office Macros

Prevent macros from running automatically, especially from untrusted sources, to reduce the risk of malware being delivered through documents.

User Application Hardening

Configure applications to reduce exploitable features — like disabling Flash, ads, and unnecessary browser functions — that can be abused by attackers.

Regular
Backups

Frequently back up important data and system configurations, and securely store copies offline to ensure quick recovery after cyber incidents like ransomware.

Understanding the Essential Eight Maturity Model

To help organisations implement the Essential Eight effectively, the Australian Signals Directorate developed a maturity model that guides the step-by-step adoption of each strategy.

Organisations should:

  • Set a target maturity level based on their risk profile and operational needs
  • Implement all eight strategies to at least the same maturity level before progressing higher
  • Use a risk-based approach, minimising exceptions and applying compensating controls when needed

The four maturity levels (from 0 to 3) help measure how effectively each strategy is deployed:

Essential Eight Implementation: Where to Begin?

  • Implementing the Essential Eight effectively starts with understanding your current security posture and setting a target maturity level that aligns with your risk profile. Each strategy should be rolled out consistently to the same maturity level before progressing further.
  • While the framework offers a clear path, successful implementation often requires expert insight to manage risks, exceptions, and unique business needs.
