Updated Essential Eight guidance for Australian customers

Amazon Web Services (AWS) is excited to announce the release of AWS Prescriptive Guidance on Reaching Essential Eight Maturity on AWS. We designed this guidance to help customers streamline and accelerate their security compliance obligations under the Essential Eight framework of the Australian Cyber Security Centre (ACSC).

What is the Essential Eight?

The Essential Eight is a security framework that the ACSC designed to help organizations protect themselves against various cyber threats. The Essential Eight covers the following eight strategies:

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

The Department of Home Affairs’ Protective Security Policy Framework (PSPF) mandates that Australian Non-Corporate Commonwealth Entities (NCCEs) reach Essential Eight maturity. The Essential Eight is also one of the compliance frameworks available to owners of critical infrastructure (CI) assets under the Critical Infrastructure Risk Management Program (CIRMP) requirements of the Security of Critical Infrastructure (SOCI) Act.

In the Essential Eight Explained, the ACSC acknowledges some translation is required when applying the principles of the Essential Eight to cloud-based environments:

“The Essential Eight has been designed to protect Microsoft Windows-based internet-connected networks. While the principles behind the Essential Eight may be applied to cloud services and enterprise mobility, or other operating systems, it was not primarily designed for such purposes and alternative mitigation strategies may be more appropriate to mitigate unique cyber threats to these environments.”

The newly released guidance walks customers step-by-step through the process of reaching Essential Eight maturity in a cloud native way, making best use of the security, performance, innovation, elasticity, scalability, and resiliency benefits of the AWS Cloud. It includes a compliance matrix that maps Essential Eight strategies and controls to specific guidance and AWS resources.

It also features an example of a customer with different workloads—a serverless data lake, a containerized webservice, and an Amazon Elastic Compute Cloud (Amazon EC2) workload running commercial-off-the-shelf (COTS) software.
