Cloud Audit: Process, Benefits & Key Steps for Australian Enterprise
A cloud audit is a comprehensive evaluation of the security measures in place within a cloud environment. Typically performed by third-party organizations to ensure compliance with industry regulations, but these audits can also be conducted internally to meet specific company standards.
The audit encompasses a range of activities, including scrutinizing security policies, assessing operational practices, physically inspecting hardware, and engaging in thorough inquiries and data analysis by the auditor.
Right here, we will cover the essentials of a cloud security audit, outline steps to effectively prepare for one, provide a detailed cloud security checklist, and offer insights on maintaining continuous, high-level security for your cloud infrastructure.
What Is A Cloud Security Audit?
A cloud audit is an assessment process that evaluates the security measures and protocols of a cloud environment to ensure they are adequate and effective.
The audit can be conducted by a third-party organization to verify compliance with industry regulations, or it can be an internal initiative to ensure that the company’s specific security standards and benchmarks are being met.

How important and beneficial are Cloud Audits
Undertaking a cloud audit is a clear indication of your organization’s commitment to maintaining high standards of security and protecting both business and customer data. Such audits are often essential for meeting industry-specific compliance requirements, which can only be confirmed through successful audit completion.
For example, organizations that handle sensitive data like credit card information must adhere to the Payment Card Industry Data Security Standards (PCI DSS). This compliance involves passing a PCI DSS audit, submitting the audit results to the relevant banking institution, and maintaining compliance until the subsequent audit.
Then, here are benefits of cloud security audits:
- Ensures adherence to industry-specific regulations and standards, avoiding legal and financial repercussions.
- Identifies and addresses vulnerabilities, strengthening overall security measures.
- Reviews and improves access controls to prevent unauthorized access.
- Evaluates the security of third-party integrations and partnerships.
- Confirms the effectiveness of backup systems and incident response plans.
- Detects and mitigates potential security threats before they can cause harm.
- Safeguards business and customer data, ensuring its integrity and confidentiality.
Core Elements of Cloud Security Audits
Cloud Infrastructure & Architecture
The foundation of any cloud platform lies in its infrastructure and controls. A cloud audit ensures that these elements adhere to best practices and maintain robust security controls. This includes enabling auditing and logging, implementing sufficient authorization controls for applications, and ensuring that services are not exposed to the public.
Data Storage & Encryption
Data within a cloud environment is constantly either at rest, in transit, or in use, often containing sensitive information vital to the business and its customers.
An audit assesses the protection mechanisms for data in all these states, verifying that proper authentication and authorization controls are in place and that encryption is used where necessary.
Identity and Access Management (IAM)
IAM is pivotal in the cloud as it governs access to business data and applications. A thorough audit of IAM practices is crucial for compliance and security.
The audit evaluates whether identities are properly inventoried, policies like Least Privilege are enforced, and best practices such as avoiding the misuse of root users are followed.
Incident Response & Disaster Recovery
An audit reviews the organization’s documentation and strategies for responding to security incidents. Effective incident response involves managing the entire incident lifecycle and minimizing damage quickly and efficiently.
Additionally, disaster recovery plans are examined to ensure there are robust procedures for data recovery and infrastructure access restoration in case of loss.
Adherence to Industry Standards & Regulations
Compliance is a key aspect of cloud security audits. Many industries require organizations to pass audits to meet regulatory standards. For example, GDPR compliance necessitates maintaining an up-to-date list of processing activities and conducting data protection impact assessments for organizations operating within the EU.
Continuous Monitoring, Logging, and Reporting
To pass a cloud audit, comprehensive logging and reporting mechanisms are essential. Logs must track all activities within the cloud environment, including infrastructure changes and identity behaviors. Continuous monitoring and ready access to these logs are critical for responding to audit queries effectively.

A Checklist of How to Conduct a Cloud Security Audit
Align with Your Cloud Service Provider (CSP)
Establish a strong relationship with your CSP and communicate with them before starting your cloud audit. Since your security heavily relies on their security practices, review their security posture thoroughly. Your CSP can provide crucial information and documentation needed for your audit.
Assess Your Attack Surface
Conduct a comprehensive inventory of your cloud environment, including infrastructure, workloads, services, data storage, containers, and identities along with their effective permissions. Classify data to prioritize the protection of the most sensitive information and applications.
Also, consider any third-party integrations, such as outsourced work or external APIs, as they can affect your security landscape.
Gather Evidence
Given the dynamic nature of the cloud, continuous monitoring and logging are essential. Collect data, screenshots, documentation, and other forms of evidence to support your audit findings.
Ensure you have detailed insights into identity activities and data access, including the privileges held by identities, their usage, and data access patterns. This evidence should be securely stored and protected.
Conduct a Risk Assessment
Analyze the collected evidence to identify security risks and vulnerabilities. Prioritize risks based on their potential impact, focusing on areas that could cause the most significant damage if compromised.
Verify Security Controls and Policies
Conduct an internal review of your security controls and policies before presenting your findings to auditors. This self-assessment helps you understand your compliance level with industry standards and identify areas that need improvement.
Compile and Present Findings
Organize all your reports, data, and documentation into a clear and comprehensive format. This final report should include all evidence, risk assessments, and a summary of your findings. Present this documentation to the auditors to demonstrate your cloud security posture.
