Security - Microsoft Workloads Lens - AWS Well-Architected Framework

Security

The security pillar within the Microsoft Workloads Lens extends the foundational security principles of the AWS Well-Architected Framework with specialized guidance tailored for Microsoft-centric environments. Rather than replacing the core Well-Architected security practices, this lens amplifies them by addressing the unique security considerations that arise when running Microsoft technologies on AWS.

This extension provides targeted security strategies for protecting Windows Server infrastructures, Active Directory implementations, SQL Server databases, Exchange Server deployments, SharePoint environments, and .NET applications. The lens integrates Microsoft security capabilities with AWS security services—including AWS IAM for identity management, AWS KMS for encryption, Amazon GuardDuty for threat detection, AWS Security Hub CSPM for centralized security posture management, and NitroTPM for hardware-based security—creating a comprehensive defense-in-depth approach.

By building upon the Well-Architected Framework's security foundation, this lens assists organizations in maintaining Microsoft workload security best practices while fully using AWS Cloud security capabilities, resulting in a hybrid security model that addresses both traditional Microsoft security requirements and modern cloud security paradigms. This includes implementing defense in depth strategies for Windows Server environments, Active Directory services, SQL Server databases, Exchange Server, SharePoint, and .NET applications, while using with AWS security services (including IAM, KMS, GuardDuty, Security Hub CSPM, and NitroTPM).

Establish proper identity and access management through AWS IAM integration with Active Directory, implement encryption at rest and in transit using AWS KMS and Microsoft TDE, and deploy comprehensive monitoring capabilities through AWS CloudTrail, Amazon CloudWatch, and Microsoft security logging. This strategy maintains strong security postures that protect against advanced persistent threats, insider threats, and compliance violations while adhering to regulatory requirements such as HIPAA, PCI DSS, SOX, and GDPR.

The pillar emphasizes the AWS shared responsibility model, where AWS secures the underlying cloud infrastructure, hypervisor, and physical facilities while customers are responsible for securing their Microsoft workloads within the cloud, including operating system hardening, application security, data classification and protection, network configuration, and identity management. This includes implementing security best practices such as least privilege access, regular security assessments, automated patch management through AWS Systems Manager, and incident response procedures tailored to Microsoft environments.

Key security considerations for Microsoft workloads include securing hybrid connectivity between on-premises Active Directory and AWS through AWS Direct Connect or Site-to-Site VPN, implementing proper network segmentation using VPCs and security groups, enabling comprehensive logging and monitoring for Windows events and Microsoft application logs, and establishing disaster recovery procedures that maintain security controls across Regions while maintaining business continuity for mission-critical Microsoft applications.
