Essential 8 Maturity Level 2: A Complete Guide for Australian Businesses

Cybersecurity remains one of the most critical responsibilities for modern businesses. As threats increase and attackers become more advanced, organisations must adopt structured security controls that reduce risk and support long-term resilience. The Essential 8 maturity level 2 standard helps businesses build stronger protection by implementing intermediate controls within the Essential 8 cybersecurity framework.

This guide explains what Essential 8 maturity level 2 includes, why it matters, and how Australian organisations can meet the Essential 8 maturity level 2 requirements.

Why Essential 8 maturity level 2 matters for business security

Achieving Essential 8 maturity level 2 provides organisations with protection against a wide range of common cyber threats. It goes beyond basic controls and creates a more structured approach to security. Many attackers exploit predictable weaknesses, outdated software, and inadequate access management. Essential 8 maturity level 2 helps eliminate these vulnerabilities.

This level also provides benefits such as:

  • Improved consistency across systems
  • Reduced exposure to ransomware and malware
  • Stronger identity and access management
  • Better patch management and application control
  • Enhanced ability to detect and respond to incidents

The Essential 8 cybersecurity framework is designed to support organisations of all sizes. Reaching level 2 shows that your business is committed to building strong cyber hygiene and protecting sensitive information.

What the Essential 8 cybersecurity framework includes

The Essential 8 cybersecurity framework, created by the Australian Cyber Security Centre, outlines eight core mitigation strategies that prevent, detect, and limit the impact of cyber attacks. These strategies become progressively more detailed as organisations advance through the maturity levels. Essential 8 maturity level 2 represents an intermediate stage where controls must be consistently applied and tested.

The eight mitigation strategies include:

  • Application control
  • Patch applications
  • Configure Microsoft Office macro settings
  • User application hardening
  • Restrict administrative privileges
  • Patch operating systems
  • Multi-factor authentication
  • Regular backups

Each control area includes Essential 8 maturity level 2 requirements that help organisations strengthen security and remove common attack pathways. Businesses must implement each area with consistency to achieve level 2.

How to meet Essential 8 maturity level 2 requirements

Meeting Essential 8 maturity level 2 requirements involves implementing structured processes, using technical controls, and ensuring all systems follow the same standards. Below is a detailed guide to understanding what each requirement means and how to apply it effectively.

Application control: stopping unauthorised software

Application control prevents unauthorised or malicious applications from running within your environment. To meet Essential 8 maturity level 2, organisations must ensure only approved applications run on workstations and servers. This includes:

  • Building an allowlist of permitted applications
  • Blocking executables from unknown locations
  • Applying controls consistently across all devices
  • Reviewing software changes regularly

Application control reduces the number of successful malware infections and supports better endpoint protection.

Patch applications: eliminating known vulnerabilities

Cyber attackers rely on unpatched software to gain access to systems. Essential 8 maturity level 2 requires patching applications within a set timeframe and ensuring updates are tested and deployed consistently. This includes:

  • Patching critical vulnerabilities within 48 hours
  • Using automated patching tools
  • Removing unsupported or outdated software
  • Reporting patch status across devices

Consistent and timely patching reduces the risk of exploitation and helps maintain system integrity.

Microsoft Office macro settings: reducing high-risk execution paths

Macros remain a common delivery method for malware. At Essential 8 maturity level 2, organisations must ensure macro settings are configured securely. Requirements include:

  • Blocking macros from the internet
  • Allowing macros only for approved, digitally signed files.
  • Preventing users from bypassing macro controls
  • Reviewing macro execution logs

Proper macro controls reduce the risk of phishing attacks and unwanted file execution.

User application hardening: closing unsafe features

User application hardening reduces attack surfaces in commonly exploited applications. Essential 8 maturity level 2 requires:

  • Disabling Flash, Java, and other deprecated technologies
  • Blocking advertisements and external scripts
  • Preventing web browsers from using risky legacy settings
  • Hardening PDF and document viewer settings

These measures make it significantly harder for attackers to exploit weaknesses in user applications.

Restrict administrative privileges: limiting damage from compromised accounts

Administrative accounts present a major risk when mismanaged. Essential 8 maturity level 2 requirements include:

  • Limiting admin access to authorised personnel only
  • Using separate admin and user accounts
  • Monitoring admin account activity
  • Reviewing privilege access risks regularly

Strong privilege management prevents attackers from gaining high-level access and reduces the impact of compromised credentials.

Patch operating systems: maintaining a secure infrastructure

Operating systems must be updated consistently to prevent vulnerabilities. Essential 8 maturity level 2 requires:

  • Applying security patches within 48 hours for critical updates
  • Using vendor-supported operating systems only.
  • Removing outdated or end-of-life systems
  • Automating patch deployment where possible

Keeping operating systems current helps maintain stability and reduces the likelihood of breaches.

Multi-factor authentication: strengthening identity security

Multi-factor authentication (MFA) provides an additional layer of security for user login attempts. At Essential 8 maturity level 2, MFA must be enabled for:

  • All remote access
  • Administrative accounts
  • Cloud services
  • Systems containing sensitive data

MFA significantly reduces the risk of unauthorised access and is one of the most effective ways to protect user accounts.

Regular backups: ensuring availability and recovery

Backups ensure your organisation can recover after an incident. Essential 8 maturity level 2 requirements include:

  • Using daily backups
  • Storing backups offline and off-site
  • Regularly testing backup restoration.n
  • Protecting backups with secure access controls

Strong backup processes help maintain business continuity during incidents such as ransomware attacks.

How Essential 8 cybersecurity assessments support compliance

Essential 8 cybersecurity assessments help organisations understand their current maturity level and identify gaps in compliance. These assessments highlight where controls are strong and where improvements are required. Regular assessments provide benefits such as:

  • Early identification of vulnerabilities
  • Better planning for upgrades and improvements
  • Clear prioritisation of risks
  • Structured guidance for achieving maturity level 2

Assessments also support reporting obligations and help align your organisation with industry best practices.

How to maintain compliance after achieving maturity level 2

Reaching Essential 8 maturity level 2 is a significant achievement, but ongoing work is required to maintain it. Continuous improvement ensures that systems remain secure and aligned with the Essential 8 cybersecurity framework.

Key steps include:

  • Regular policy reviews
  • Continuous patch monitoring
  • Ongoing staff training
  • Routine Essential 8 cybersecurity assessments
  • Strengthening controls as new threats emerge

Maintaining level 2 provides long-term protection and supports future progression to level 3 as your organisation matures.

Final thoughts

Achieving Essential 8 maturity level 2 helps businesses reduce risk, simplify compliance, and build stronger cyber resilience. The Essential 8 cybersecurity framework provides structured guidance for implementing effective security practices across applications, systems, and user controls. By understanding the Essential 8 maturity level 2 requirements and performing regular Essential 8 cybersecurity assessments, organisations can strengthen their defences and protect their operations in a rapidly evolving threat landscape.
