AWS News Blog – AWS Audit Manager Simplifies Audit Preparation

Bron: AWS News Blog

Gathering evidence in a timely manner to support an audit can be a significant challenge due to manual, error-prone, and sometimes, distributed processes. If your business is subject to compliance requirements, preparing for an audit can cause significant lost productivity and disruption as a result. You might also have trouble applying traditional audit practices, which were originally designed for legacy on-premises systems, to your cloud infrastructure.

To satisfy complex and evolving sets of regulation and compliance standards, including the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), and Payment Card Industry Data Security Standard (PCI DSS), you’ll need to gather, verify, and synthesize evidence.

You’ll also need to constantly reevaluate how your AWS usage maps to those evolving compliance control requirements. To satisfy requirements you may need to show data encryption was active, and log files showing server configuration changes, diagrams showing application high availability, transcripts showing required training was completed, spreadsheets showing that software usage did not exceed licensed amounts, and more. This effort, sometimes involving dozens of staff and consultants, can last several weeks.

Available today, AWS Audit Manager is a fully managed service that provides prebuilt frameworks for common industry standards and regulations, and automates the continual collection of evidence to help you in preparing for an audit. Continuous and automated gathering of evidence related to your AWS resource usage helps simplify risk assessment and compliance with regulations and industry standards and helps you maintain a continuous, audit-ready posture to provide a faster, less disruptive preparation process.

Built-in and customizable frameworks map usage of your cloud resources to controls for different compliance standards, translating evidence into an audit-ready, immutable assessment report using auditor-friendly terminology. You can also search, filter, and upload additional evidence to include in the final assessment, such as details of on-premises infrastructure, or procedures such as business continuity plans, training transcripts, and policy documents.

Given that audit preparation typically involves multiple teams, a delegation workflow feature lets you assign controls to subject-matter experts for review. For example, you might delegate reviewing evidence of network security to a network security engineer.

The finalized assessment report includes summary statistics and a folder containing all the evidence files, organized in accordance with the exact structure of the associated compliance framework. With the evidence collected and organized into a single location, it’s ready for immediate review, making it easier for audit teams to verify the evidence, answer questions, and add remediation plans.

Getting started with Audit Manager
Let’s get started by creating and configuring a new assessment. From Audit Manager‘s console home page, clicking Launch AWS Audit Manager takes me to my Assessments list (I can also reach here from the navigation toolbar to the left of the console home). There, I click Create assessment to start a wizard that walks me through the settings for the new assessment. First, I give my assessment a name, optional description, and then specify an Amazon Simple Storage Service (S3) bucket where the reports associated with the assessment will be stored.

Next, I choose the framework for my assessment. I can select from a variety of prebuilt frameworks, or a custom framework I have created myself. Custom frameworks can be created from scratch or based on an existing framework. Here, I’m going to use the prebuilt PCI DSS framework.

Since I have a single account, I select it and click Next, moving on to select the AWS services that I want to be included in evidence gathering. I’m going to include all the suggested services (the default) and click Next to continue.

You must select at least one owner, so I select my account and click Next to move to the final Review and create page. Finally, clicking Create assessment starts the gathering of evidence for my new assessment. This can take a while to complete, so I’m going to switch to another assessment to examine what kinds of evidence I can view and choose to include in my assessment report.

Back in the Assessments list view, clicking on the assessment name takes me to details of the assessment, a summary of the controls for which evidence is being collected, and a list of the control sets into which the controls are grouped. Total evidence tells me the number of events and supporting documents that are included in the assessment. The additional tabs can be used to give me insight into the evidence I select for the final report, which accounts and services are included in the assessment, who owns it, and more. I can also navigate to the S3 bucket in which the evidence is being collected.

If I change a control to be Inactive, meaning automated evidence gathering will cease for that control, this is logged.

Expanding Default control set, I click control 8.1.2 For a sample of privileged user IDs… which takes me to a view giving more detailed information on the control and how it is tested. Scrolling down, there is a set of evidence folders listed and here I notice that there are some issues. Clicking the issue link in the Compliance check column summarizes where the data came from. Here, I can also select the evidence that I want included in my final report.

For the purposes of this post I’ve gone ahead and selected evidence for a handful of controls into my report. Then, I selected the Assessment report selection tab, where I review my evidence selections, and clicked Generate assessment report. In the dialog that appeared I gave my report a name, and then clicked Generate assessment report. When the dialog closes I am taken to the Assessment reports view and, when my report is ready, I can select it and download a zip file containing the report and the selected evidence. Alternatively, I can open the S3 bucket associated with the assessment (from the assessment’s details page) and view the report details and evidence there, as shown in the screenshot below. The overall report is listed (as a PDF file) and if I drill into the evidence folders, I can also view PDF files related to the specific items of evidence I selected.
