Essential Eight — ASD Cybersecurity Strategies
The Australian government's baseline cybersecurity standard
The Essential Eight is the Australian Signals Directorate's (ASD) prioritised set of eight mitigation strategies that, when implemented correctly, make it significantly harder for adversaries to compromise systems.
The Essential Eight is developed and maintained by the Australian Signals Directorate (ASD) as part of its Strategies to Mitigate Cyber Security Incidents. It represents the eight most effective cybersecurity controls that prevent the vast majority of cyber attacks. The strategies are organised into four maturity levels (0–3), allowing organisations to progressively improve their cybersecurity posture.
Compliance with the Essential Eight is mandatory for many Australian Government non-corporate Commonwealth entities (NCEs) and is increasingly adopted as a baseline standard by state and local governments, critical infrastructure operators, and private sector organisations. The ASD's 2023 Annual Cyber Threat Report consistently highlights that most successful attacks could have been prevented by implementing the Essential Eight to Maturity Level 2.
Who Needs It
Who Needs Essential 8?
Australian Government non-corporate Commonwealth entities (mandatory)
State and local government agencies adopting Commonwealth security standards
Critical infrastructure operators in sectors regulated under the Security of Critical Infrastructure Act
Private sector organisations seeking a practical, government-endorsed security baseline
Government contractors and suppliers handling Australian Government data
Organisations wanting to demonstrate security maturity to government and enterprise customers
Key Requirements
What It Covers
Application Control
Prevent execution of unapproved/malicious programs including .exe, DLL, scripts, and installers — one of the most effective controls against ransomware.
Patch Applications
Patch or mitigate vulnerabilities in internet-facing services within 48 hours (critical) and 2 weeks (non-critical) — essential against known exploit campaigns.
Configure Microsoft Office Macro Settings
Block Microsoft Office macros from the internet and restrict macro execution to vetted, signed macros — targeting a primary phishing payload delivery mechanism.
User Application Hardening
Configure web browsers, Office, and PDF viewers to block ads, disable unneeded features like Flash and OLE, and prevent web-based malware execution.
Restrict Administrative Privileges
Minimise admin accounts, use separate admin accounts for privileged tasks, and require Just-In-Time (JIT) administration — limiting lateral movement.
Patch Operating Systems
Patch or mitigate OS vulnerabilities, prioritising internet-exposed systems. Replace unsupported operating systems that no longer receive security updates.
Multi-Factor Authentication (MFA)
Implement phishing-resistant MFA for all remote access, privileged accounts, and third-party services storing sensitive data.
Regular Backups
Perform and test regular backups of important data, software, and configuration settings. Maintain offline or immutable copies to recover from ransomware.
Business Value
