Cloud Security Configuration Baseline Check Checklist [FREE PDF]

Cloud security configuration baseline checks are essential for ensuring that cloud environments meet regulatory and organizational security requirements as defined by NIST CSF 2.0 and ISO 27001:2022. Misconfigurations remain the leading cause of cloud data breaches, making systematic audits a critical control for any organization handling sensitive data. This checklist guides security teams through a structured assessment of identity controls, network security, logging, encryption, and third-par

  • Industry: Information Security
  • Frequency: Monthly
  • Estimated Time: 45-60 minutes

Identity & Access Management (IAM)

Verify that identity controls, privilege boundaries, and authentication mechanisms are properly configured in the cloud environment.

  • Is multi-factor authentication (MFA) enforced for all IAM users with console or API access?
  • Are root or super-admin accounts disabled for routine operations and restricted to break-glass procedures?
  • Have all unused IAM accounts and service principals been disabled or removed within the last 90 days?
  • Is role-based access control (RBAC) implemented and reviewed at least quarterly?
  • Are service account keys and API credentials rotated at least every 90 days?
  • Are privileged access sessions recorded and auditable for all administrative cloud actions?

Network Security & Perimeter Controls

Assess the configuration of firewalls, security groups, VPC settings, and network segmentation to prevent unauthorized access.

  • Are all cloud security groups and firewall rules configured to deny inbound traffic by default?
  • Are publicly exposed storage buckets, databases, or compute instances identified and remediated?
  • Is VPC/VNet segmentation in place to isolate production from development and staging environments?
  • Is a Web Application Firewall (WAF) enabled and actively protecting internet-facing cloud workloads?
  • Are all unused open ports and services disabled or blocked at the cloud security group level?

Data Protection & Encryption

Confirm that data at rest and in transit is encrypted according to applicable regulatory standards and organizational policy.

  • Is encryption at rest enabled for all cloud storage, databases, and virtual machine disks containing sensitive data?
  • Is TLS 1.2 or higher enforced for all data in transit between cloud services and external endpoints?
  • Are encryption keys stored in a dedicated key management service (KMS) separate from the encrypted data?
  • Is a data classification policy applied to cloud-stored assets to govern encryption and access requirements?
  • Are backups of sensitive cloud data encrypted and stored in a geographically separate region or account?
  • Is data loss prevention (DLP) tooling configured to detect and alert on sensitive data exfiltration attempts?

Logging, Monitoring & Alerting

Evaluate the completeness of audit logging, real-time monitoring, and alerting configurations across cloud services.

  • Is centralized audit logging enabled for all cloud control plane and data plane activities?
  • Are cloud audit logs retained for a minimum of 12 months with at least 3 months immediately accessible?
  • Are automated alerts configured for critical events such as root logins, policy changes, and security group modifications?
  • Is a Security Information and Event Management (SIEM) system ingesting and correlating cloud logs in real time?
  • Are log integrity controls in place to prevent tampering or deletion of audit records?

Vulnerability & Patch Management

Confirm that cloud workloads are scanned for vulnerabilities and that patches are applied within approved timeframes.

  • Are automated vulnerability scans executed on all cloud workloads at least weekly?
  • Are critical and high-severity vulnerabilities remediated within 30 days of discovery?
  • Are container images and serverless function dependencies scanned for known CVEs before deployment?
  • Is a formal change management process enforced before applying patches to production cloud systems?
  • Is a software bill of materials (SBOM) maintained for all cloud-deployed applications and services?

Configuration Hardening & Baseline Compliance

Verify that cloud resources are configured against industry-accepted security benchmarks and hardening standards.

  • Are all cloud resources deployed using infrastructure-as-code (IaC) templates with embedded security controls?
  • Are cloud benchmarks (e.g., CIS Cloud Foundations Benchmark) applied and compliance continuously assessed?
  • Is cloud security posture management (CSPM) tooling deployed to detect configuration drift in real time?
  • Are default passwords and credentials changed for all cloud-managed services and administrative consoles?
  • Is the number of cloud regions and services in use limited to only those operationally required?

Third-Party & Cloud Vendor Risk

Assess controls over cloud service providers, SaaS integrations, and third-party access to the cloud environment.

  • Is a current inventory of all third-party cloud integrations and SaaS applications maintained?
  • Are third-party vendors with cloud access subject to formal security assessments prior to onboarding?
  • Is third-party cloud access limited using just-in-time (JIT) provisioning or time-bound credentials?
  • Does the cloud service provider supply an annual SOC 2 Type II or equivalent attestation report?
  • Are shared responsibility model boundaries documented and reviewed for each cloud service provider relationship?
