This curriculum spans the equivalent of a multi-workshop technical engagement, covering the design, migration, and operational enforcement of cloud security controls across identity, data, network, and development environments, comparable to an internal capability-building program for cloud security teams in large enterprises.

Module 1: Assessing Cloud Security Posture Prior to Migration

  • Conduct a risk assessment of on-premises workloads to determine which systems can safely be migrated based on data sensitivity and compliance requirements.
  • Map existing identity and access management policies to target cloud provider models, identifying gaps in role definitions and authentication mechanisms.
  • Inventory legacy applications with hardcoded credentials or unpatched vulnerabilities that require refactoring before migration.
  • Evaluate data residency and sovereignty constraints to determine permissible cloud regions and availability zones.
  • Define security baselines for workloads using CIS Benchmarks or NIST frameworks tailored to the cloud environment.
  • Establish cross-functional alignment between security, infrastructure, and application teams on security ownership during and after migration.

Module 2: Designing Secure Cloud Landing Zones

  • Implement multi-account strategies using AWS Organizations, Azure Management Groups, or GCP Folders to enforce isolation between production, development, and sensitive workloads.
  • Configure centralized logging and monitoring at the organization level to capture control plane and data plane events across all accounts.
  • Enforce network segmentation using hub-and-spoke or mesh topologies with managed firewalls and routing policies.
  • Deploy identity federation using SAML or OIDC to integrate with existing enterprise identity providers, avoiding local cloud user creation.
  • Define and automate guardrail policies using Infrastructure as Code (IaC) tools like Terraform or CloudFormation with policy-as-code frameworks such as HashiCorp Sentinel or AWS Config Rules.
  • Set up secure initial administrative access using just-in-time (JIT) and privileged access management (PAM) solutions to limit standing privileges.

Module 3: Securing Data During and After Migration

  • Classify data by sensitivity level and apply encryption accordingly—enabling SSE-S3, SSE-KMS, or client-side encryption based on regulatory needs.
  • Implement data loss prevention (DLP) policies in transit and at rest using cloud-native tools like Amazon Macie, Azure Information Protection, or Google Cloud DLP.
  • Manage encryption key lifecycles using cloud key management services (KMS) with regular rotation and separation of duties for key administrators.
  • Design secure data pipelines for bulk migration using encrypted connections and temporary access credentials with expiration.
  • Apply retention and deletion policies aligned with legal holds and data minimization principles to prevent indefinite data storage.
  • Monitor for unauthorized data access patterns using anomaly detection rules in security information and event management (SIEM) systems.

Module 4: Identity and Access Management at Scale

  • Define granular least-privilege IAM roles and policies using attribute-based access control (ABAC) to reduce policy sprawl.
  • Integrate workload identities with Kubernetes service accounts using cloud-specific mechanisms like AWS IAM Roles for Service Accounts (IRSA) or Azure Workload Identity.
  • Implement service account hardening by disabling user-like access, enforcing key rotation, and monitoring for misuse.
  • Enforce conditional access policies based on IP location, device compliance, and risk level for human users.
  • Conduct quarterly access reviews using automated certification campaigns to revoke unnecessary permissions.
  • Deploy privileged identity management (PIM) for time-bound elevation of administrative privileges with audit trail capture.

Module 5: Securing Network Architecture in the Cloud

  • Design hybrid connectivity using AWS Direct Connect, Azure ExpressRoute, or Google Cloud Interconnect with encrypted tunnels and BGP security controls.
  • Implement micro-segmentation using security groups and network firewalls to restrict east-west traffic between workloads.
  • Configure DNS protection using private zones and DNS filtering to prevent data exfiltration via DNS tunneling.
  • Deploy Web Application Firewalls (WAF) in front of public-facing applications with custom rules to block OWASP Top 10 threats.
  • Enforce egress filtering using firewall appliances or cloud-native controls to prevent unauthorized outbound connections.
  • Isolate high-risk workloads in dedicated VPCs/VNets with no public internet access and strict peering policies.

Module 6: Continuous Security Monitoring and Incident Response

  • Aggregate logs from cloud platforms, workloads, and third-party tools into a centralized SIEM with normalized schemas for correlation.
  • Develop detection rules for suspicious activities such as root account usage, unauthorized configuration changes, or mass data downloads.
  • Integrate cloud security posture management (CSPM) tools to continuously scan for misconfigurations and compliance drift.
  • Automate response playbooks using SOAR platforms to quarantine resources, disable credentials, or isolate networks upon detection.
  • Conduct tabletop exercises simulating cloud-specific incidents like S3 bucket exposure or compromised container images.
  • Establish cloud-specific forensic data collection procedures, including memory dumps, container snapshots, and API call logs.

Module 7: Governance, Compliance, and Audit Readiness

  • Map cloud resource configurations to regulatory frameworks such as HIPAA, GDPR, or PCI-DSS using automated compliance scoring tools.
  • Implement tagging standards for cost, ownership, environment, and data classification to support policy enforcement and reporting.
  • Generate audit trails for configuration changes using cloud-native tools like AWS CloudTrail, Azure Activity Log, or GCP Audit Logs.
  • Define ownership models for cloud resources to ensure accountability and timely remediation of security findings.
  • Coordinate third-party audits by preparing evidence packages that demonstrate control implementation across shared responsibility boundaries.
  • Establish change advisory boards (CABs) for high-risk modifications to network, identity, or security configurations.

Module 8: Securing Cloud-Native Applications and Development Pipelines

  • Integrate static application security testing (SAST) and software composition analysis (SCA) into CI/CD pipelines to block vulnerable code.
  • Scan container images for OS vulnerabilities and misconfigurations using tools like Trivy or Amazon ECR scanning before deployment.
  • Enforce immutable infrastructure principles by preventing runtime modifications and requiring redeployment for changes.
  • Secure artifact repositories with access controls, virus scanning, and digital signing to prevent tampering.
  • Implement infrastructure as code (IaC) security scanning using Checkov or tfsec to detect risky configurations pre-deployment.
  • Define deployment gates in CI/CD workflows that require security approval for production promotions.
