INDEPENDENT CLOUD ASSURANCE
What is a cloud security audit?
A cloud security audit is an independent examination of cloud configurations, access controls, operational processes and supporting evidence. It determines whether security controls are suitably designed, applied within the agreed scope and operating as expected at the time of the review.
The audit scope may cover one workload, a cloud account, a group of subscriptions or a wider multi-cloud estate. Digisecuritas agrees the audit criteria, access arrangements, evidence requirements and reporting boundaries before fieldwork begins.
"Cloud assurance depends on what can be demonstrated, not what is assumed."
AUDIT CONTROL LEDGER
Every Finding Must Connect Control, Evidence and Risk
Digisecuritas records how each audit conclusion was reached. The control ledger connects the requirement being tested with the evidence reviewed, the observed condition, the resulting risk and the action owner.
Identity administration
Privileged access is approved and restricted.
Role assignments, access policies and approval records.
Record the configuration and supporting evidence found during the audit.
Determine the effect of excessive or unaccountable access.
Assign remediation to the appropriate identity or platform owner.
Evidence availablePublic exposure
Internet-facing resources are intentionally approved and protected.
Network rules, public endpoints, routing and asset ownership.
Record exposed services and the business context supplied.
Assess whether exposure exceeds the intended requirement.
Restrict, protect or formally accept the identified exposure.
Further evidence requiredData protection
Sensitive data receives appropriate access and encryption controls.
Storage policies, encryption settings, key-management records and data classification.
Compare the technical configuration with the stated handling requirement.
Identify material gaps affecting confidentiality or control over key use.
Define the configuration, ownership or governance change required.
Control observationLogging and monitoring
Relevant activity is recorded, retained and available for investigation.
Audit-log settings, retention controls, alert routes and monitoring responsibilities.
Determine whether required events are captured across the agreed scope.
Assess how missing records could affect detection, investigation or assurance.
Assign logging, retention or integration improvements.
Remediation requiredChange governance
Material cloud changes follow an approved and traceable process.
Change records, infrastructure-as-code repositories, approvals and deployment logs.
Compare deployed changes with the organisation's stated control process.
Identify unapproved changes, configuration drift or weak separation of duties.
Strengthen approval, validation or deployment governance.
Management decisionAUDIT SCOPE
Define the Audit Around the Decision You Need to Make
The audit boundary should reflect the business question behind the review. Digisecuritas can assess a focused workload or a broader cloud estate without treating every engagement as the same exercise.
Focused workload audit
Review the cloud services, identities, network paths, data controls and operational processes supporting one defined application or business service.
Suitable when
- Preparing an important workload for launch
- Responding to a customer security requirement
- Validating a material architecture change
- Reviewing a sensitive data environment
Cloud account or subscription audit
Assess the governance and configuration of a defined AWS account, Azure subscription, GCP project or equivalent administrative boundary.
Suitable when
- Ownership is clearly separated by account or subscription
- A business unit requires independent validation
- A platform team needs a configuration baseline
- A new environment is entering production use
Multi-account or multi-subscription review
Examine common controls, policy consistency and material exceptions across a group of connected environments.
Suitable when
- Cloud use has expanded across multiple teams
- Security settings vary between environments
- Central governance needs independent validation
- Management requires consolidated risk visibility
Multi-cloud security audit
Review control consistency and ownership across approved cloud providers while respecting the technical differences between their services.
Suitable when
- Critical services operate across more than one provider
- Leadership needs a consolidated risk view
- Identity and logging responsibilities are fragmented
- Common policies are applied differently by platform teams
Scope note: The final scope, sample size and depth of testing depend on the audit objective, available evidence, access permissions, cloud architecture and agreed audit criteria.
CLOUD CONTROL DOMAINS
Cloud Controls Examined in Context
Governance and ownership
Review cloud policies, account structures, responsibility assignments, exceptions and management oversight.
Discuss this audit area →Identity and privileged access
Assess role assignments, administrative permissions, authentication controls, service identities and access-review practices.
Discuss this audit area →Network security
Review public endpoints, security rules, routing, segmentation, private connectivity and management access.
Discuss this audit area →Data protection
Assess storage access, encryption configuration, key ownership, secret handling, backup protection and relevant data-location controls.
Discuss this audit area →Logging and monitoring
Review activity logging, security-event coverage, retention, alert routing and responsibilities for investigating material events.
Discuss this audit area →Workload configuration
Examine the security settings of defined compute, container, serverless, database and storage services within scope.
Discuss this audit area →Vulnerability and patch governance
Review how relevant vulnerabilities, unsupported components, operating-system updates and remediation actions are identified and managed.
Discuss this audit area →Change and deployment controls
Assess approval routes, infrastructure-as-code practices, deployment permissions, configuration drift and emergency changes.
Discuss this audit area →Resilience and recovery
Review security-relevant backup access, recovery responsibilities, account dependencies and protection of recovery resources.
Discuss this audit area →Testing depth depends on the services in use and the agreed audit scope. Not every possible cloud service is examined in every engagement.
AUDIT CRITERIA
Audit Criteria Agreed Before Testing Begins
An audit needs defined criteria. Digisecuritas works with the client to select the policies, obligations and recognised guidance that apply to the environment and the purpose of the review.
Alignment is not certification
A cloud security audit can assess controls against selected requirements and support readiness work. It does not automatically issue ISO certification, a SOC 2 report or regulatory approval.
- Certification and formal attestation require the appropriate accredited or licensed body.
- Framework mapping does not mean every framework control applies to every environment.
- Cloud-provider recommendations must be interpreted within the organisation's architecture and risk.
- The audit report states the criteria, scope, limitations and evidence used.
AUDIT PROCESS
A Defined Audit From Scope to Remediation
Establish scope
Confirm the audit objective, cloud boundaries, systems, business services, responsible teams, audit criteria and known limitations.
Output
Approved scope and evidence request.
Collect evidence
Obtain authorised read-only access where appropriate and review configurations, exports, policies, logs, diagrams, tickets and interviews.
Output
Evidence register with identified gaps.
Test controls
Compare the collected evidence with the agreed criteria. Validate material conditions through configuration review, sampling and authorised technical checks.
Output
Documented control observations.
Determine risk
Assess the likelihood, exposure, business effect and control context of each material observation.
Output
Prioritised findings with clear reasoning.
Report and support closure
Present technical findings, executive implications, remediation priorities and responsible owners. Revalidation can be scoped after corrective action.
Output
Final audit report and remediation roadmap.
Digisecuritas performs testing within the approved boundaries. The client retains responsibility for cloud ownership, production changes, risk acceptance and decisions outside the agreed engagement.
FINDINGS AND DELIVERABLES
Findings Written for Remediation, Not Decoration
Executive note
Leadership receives a concise account of material exposure, control ownership, unresolved decisions and the actions that require management attention.
