![]() ![]() This guide defines four levels of evidence quality: ![]() As such, when conducting an assessment, assessors should seek to gather and use the highest quality evidence where reasonably practicable. In general terms, the evidence used to determine the effectiveness of controls will vary in quality depending on the approach taken. In conducting an assessment, assessors need to gather and review credible evidence to support conclusions they draw on the effectiveness of controls. This will assist in ensuring that an equivalent level of overall protection against a specific level of adversary targeting and tradecraft can be achieved and maintained. In these instances, such as for Linux workstations and servers, cloud computing or enterprise mobility, organisations should consider alternative guidance provided by the ACSC.įinally, in determining compensating control effectiveness, assessors should ensure that any compensating controls that have been implemented provide an equivalent level of protection to those recommended under the Essential Eight. While the Essential Eight may be applied to a non-Microsoft Windows system, specific mitigation strategies, or parts thereof, may not be applicable or even the most effective mitigation strategies available. As such, the guidance in this publication should be incorporated by assessors, noting that assessors should still use their own judgement and expertise. The maturity model also includes Maturity Level Zero which exists for capturing instances in which the requirements of Maturity Level One are not met.Īlthough the approach to conducting an assessment depends on the size and complexity of a system, there are foundational principles that are common to each assessment. This maturity model describes three target maturity levels (Maturity Level One through to Maturity Level Three) which are based on mitigating increasing levels of adversary targeting and tradecraft. OverviewĪssessments against the Essential Eight are conducted using the Essential Eight Maturity Model. Note, all vendor products mentioned within this publication are for illustrative purposes only and should not be interpreted as an explicit endorsement by the ACSC. Essential Eight Assessment Report Template.This publication should be read and used in conjunction with other ACSC guidance and tools. In doing so, it includes guidance on assessment methods that can be used for assessing both the implementation and effectiveness of controls that underpin the Essential Eight – as articulated within the Essential Eight Maturity Model (November 2022 release). ![]() This publication details a process for undertaking assessments of the Essential Eight. The most effective of these mitigation strategies are the Essential Eight. The Australian Cyber Security Centre (ACSC) has developed prioritised mitigation strategies, in the form of the Strategies to Mitigate Cyber Security Incidents, to help organisations protect themselves against various cyber threats. ![]()
