Glossary / Cloud Security Testing
Cloud Security Testing
Cloud security testing is a hands-on assessment of cloud configurations, identities, and network paths in AWS, Azure, or GCP to confirm whether misconfigurations are actually exploitable. It documents what can be reached, how an attacker would move, and what to fix first.
It differs from posture scans by validating access paths across services (identity to compute to data) rather than listing isolated findings. The outcome is a clear map of reachable assets and the specific conditions that make them reachable.
A good test records evidence for each risk: affected resources, permissions involved, and the shortest exploit path. This makes it easier for engineering and security teams to review, prioritize, and explain fixes internally.
Remediation guidance focuses on precise changes (least-privilege IAM, network segmentation, and storage access controls) tied to the tested paths, so teams can verify closure with confidence.
AWS, Azure, and GCP require different testing lenses
Attack paths in the cloud are built from identity, control-plane permissions, and service-to-service trust. We test how those paths chain together in each provider, then tie the findings to the exact configurations that enabled them.
AWS focus areas
We validate how permissions and trust relationships combine across accounts and services.
- IAM policy evaluation, SCPs, and resource policies to identify escalation paths
- Role chaining and STS assumptions that extend access beyond the initial identity
- S3, KMS, and data access paths linked to the compromised role or service
Azure focus areas
We map identity and resource access across tenants, subscriptions, and role inheritance.
- Entra ID role assignments and service principals that expand privileges
- Azure RBAC scope inheritance across management groups and subscriptions
- Storage account, Key Vault, and secret access tied to those roles
GCP focus areas
We trace service account permissions and project-level controls that govern reachability.
- IAM bindings and service account usage that enable lateral movement
- Org/folder/project policy inheritance and VPC firewall rules
- Cloud Storage and workload identity access from compromised workloads
How Appsecco connects this to testing
- Start from realistic entry points like a compromised workload or a limited-scope key
- Follow the shortest permission chain to sensitive actions or data access
- Document evidence and retest the exact path after remediation
Common cloud misconfigurations that create real attack paths
Most cloud issues are not single settings in isolation. They become meaningful when identity, trust, and exposure chain together. We test these combinations to confirm what is actually reachable and why.
Over-permissive identities and wildcard policies
Roles, service accounts, or managed identities carry broad permissions that look convenient but allow unintended access once any workload or key is compromised.
Resolution: We calculate effective permissions, then validate the shortest path from that identity to sensitive actions or data.
Trust relationships that extend access
Cross-account roles, federated identities, and service principals inherit trust without strong conditions, expanding access across subscriptions, projects, or accounts.
Resolution: We attempt safe role assumptions and verify whether trust constraints (external IDs, conditions, MFA) are enforceable in practice.
Public or overly broad storage access
Buckets, containers, or disks allow list/read access beyond intended identities, sometimes through inherited policies or shared keys.
Resolution: We validate which identities can reach data and document the precise policy or ACL that enabled access.
Default workload identities with broad reach
Compute workloads run with default identities or tokens that can call high-privilege APIs or access secrets.
Resolution: We trace from a compromised workload to the control-plane actions and data it can reach, then map safer least-privilege alternatives.
Network exposure without access-path validation
Open security groups, firewall rules, or public endpoints create reachability, but the impact depends on what those services can do once reached.
Resolution: We confirm which exposed endpoints allow meaningful access and tie them to the permissions and data behind them.
Cloud security testing methodology
A cloud security test follows a defined sequence so teams know what will happen, what is in scope, and how results will be validated without disruption.
Methodology is designed to be predictable and reversible, with explicit boundaries that protect production and operations.
Scope and safe access setup
Confirm accounts, subscriptions, projects, and environments in scope. Establish read-only or least-privilege access and define stop conditions so testing remains controlled.
Attack-path mapping
Map how identity, control-plane permissions, and network exposure combine to create reachable paths, focusing on realistic entry points.
Controlled validation
Validate the shortest exploit path using non-destructive steps and clear evidence so results are reproducible and defensible.
Reporting and retest plan
Document affected assets, permissions, and precise fixes, then define how each path will be retested after remediation.
CSPM tools vs. cloud security testing
If CSPM is already part of your program, that is a reasonable and common starting point. CSPM is built for continuous coverage and compliance signals; cloud security testing validates which access paths are actually exploitable and why.
CSPM (posture management)
Continuous scanning for known misconfigurations and policy drift.
- Provides broad inventory and compliance visibility across accounts
- Finds per-resource issues but does not prove exploitability
- High alert volume can hide the paths that matter most
Cloud security testing
Human-led validation of real access paths under a defined scope.
- Chains identity, network, and data controls to prove reachability
- Documents evidence and the shortest path so fixes are defensible
- Produces a clear retest plan tied to each validated path
How teams use both
- Use CSPM for baseline visibility and continuous guardrails.
- Use testing when CSPM findings need validation or when risk must be explained.
- Prioritize fixes based on evidence-backed paths and retest results.
Appsecco's methodology is designed for controlled, evidence-based validation without disrupting production.
