What is the Essential Eight?
The Essential Eight is a cybersecurity framework developed by the Australian Cyber Security Centre (ACSC) to help organizations mitigate cyber threats. It comprises eight critical mitigation strategies designed to prevent attacks, limit their impact, and facilitate recovery.
The Essential Eight is particularly relevant to Australian businesses, government entities, and organizations handling sensitive information or critical infrastructure. While initially tailored for public sector organizations, it has gained traction across industries such as healthcare, finance, education, and utilities. Compliance with the Essential Eight is increasingly recommended by regulatory bodies and aligns with laws such as the Security of Critical Infrastructure Act 2018 and the Privacy Act 1988.
The ACSC periodically updates the Essential Eight Maturity Model to reflect evolving threats and technological advancements. In recent years, updates have focused on enhancing the granularity of maturity levels and clarifying implementation strategies.
What are the requirements for Essential Eight?
Achieving compliance with the Essential Eight requires implementing and maintaining the eight strategies effectively. Organizations must assess their current cybersecurity posture and take actionable steps to meet the maturity level appropriate for their risk profile.
Key Prerequisites:
- Baseline Security Assessment: Evaluate current cybersecurity practices against the Essential Eight Maturity Model.
- Resource Allocation: Assign sufficient budget, tools, and personnel to implement and maintain the controls.
- Leadership Buy-In: Ensure executive support to prioritize cybersecurity investments.
The Essential Eight Controls
- Application Control: Restrict the execution of unapproved applications.
- Patch Applications: Regularly update software to address security vulnerabilities.
- Configure Microsoft Office Macro Settings: Limit or block macros to prevent malicious code execution.
- User Application Hardening: Disable unnecessary features like Flash or Java.
- Restrict Administrative Privileges: Limit admin rights to minimize the impact of breaches.
- Patch Operating Systems: Regularly update operating systems with the latest security patches.
- Multi-Factor Authentication (MFA): Enforce MFA for access to critical systems and data.
- Regular Backups: Perform frequent data backups and test restoration processes.
Maturity Levels
The Essential Eight Maturity Model defines four maturity levels:
- Maturity Level Zero: Not aligned with the intent of the mitigation strategy.
- Maturity Level One: Partially aligned with the intent of the mitigation strategy.
- Maturity Level Two: Mostly aligned with the intent of the mitigation strategy.
- Maturity Level Three: Fully aligned with the intent of the mitigation strategy.
Organizations should aim to achieve the same maturity level across all eight mitigation strategies before progressing to higher levels.
The ACSC oversees the Essential Eight framework, while organizations are encouraged to work with accredited cybersecurity professionals for assessments and implementation.
There is no mandatory requirement for organizations to have their Essential Eight implementation certified by an independent party. However, independent assessments may be necessary if mandated by a government directive or policy (e.g. RFFR), required by a regulatory authority, or stipulated as part of contractual agreements.
Essential Eight within the RFFR Requirements
The Essential Eight cybersecurity framework is integral to the Right Fit for Risk (RFFR) accreditation process established by the Australian Department of Employment and Workplace Relations. RFFR mandates that service providers implement and manage a set of core expectations to maintain and enhance their security posture. A key component of these expectations is the adoption of the Essential Eight strategies.
Under RFFR, providers are required to determine a target maturity level for each of the Essential Eight strategies that reflects their organization’s risk profile. Initially, providers must implement controls supporting the Essential Eight to achieve Maturity Level One on the Australian Cyber Security Centre’s (ACSC) published maturity model. This foundational level ensures that basic cybersecurity measures are in place, forming the baseline for more advanced security practices.
By integrating the Essential Eight into the RFFR framework, the Department ensures that providers adopt a standardized and effective approach to cybersecurity. This alignment not only enhances the security of the services delivered but also ensures compliance with governmental cybersecurity expectations, thereby safeguarding sensitive information and maintaining trust in public services.
