Overview
Sistemas is a technology solutions provider focused on helping organizations modernize their IT environments through secure, scalable, and efficient digital platforms. As part of its ongoing cloud transformation efforts, the company initiated a project to strengthen its AWS security posture and modernize its legacy database infrastructure.
The existing environment presented challenges related to inconsistent encryption practices, manual identity and access management, and limited visibility into system activity. In addition, the organization’s on-premises SQL Server 2016 database required modernization to improve performance, security, and scalability.
To address these requirements, Sistemas partnered with OneData to implement AWS-native security controls, establish automated governance, and migrate its database to Amazon RDS—enabling a more secure, compliant, and resilient cloud environment.

Opportunity | Improving Security Governance and Modernizing Legacy Systems
The legacy environment exposed multiple operational and security risks, including inconsistent encryption standards, manual IAM key management, and lack of centralized monitoring and audit visibility. These limitations increased the complexity of securing workloads, managing credentials, and maintaining compliance.
At the same time, the organization’s on-premises SQL Server 2016 database required modernization to address performance, scalability, and security requirements. Compliance gaps with CIS AWS Foundations Benchmark standards further emphasized the need for a structured and automated approach to security and governance.
Sistemas required a solution to strengthen identity and access controls, improve monitoring and audit capabilities, implement consistent encryption, and modernize its database infrastructure while ensuring data integrity and operational continuity.
Solution | Implementing Security Controls and Migrating to Amazon RDS
Sistemas approached OneData to implement a structured approach focused on strengthening security controls, improving governance, and modernizing its database infrastructure using AWS-native services.
Identity and access management controls were enhanced through password policy enforcement and automated IAM access key rotation. A Lambda-based mechanism was implemented to detect and rotate access keys older than 90 days, supported by notification and logging systems. Tools such as IAM Access Analyzer, AWS CloudTrail, AWS Config, and AWS Security Hub were used to improve visibility, detect external access, and enable continuous compliance monitoring.
Security services including Amazon GuardDuty and Amazon Inspector were deployed to enable threat detection and vulnerability assessment across workloads. Monitoring capabilities were further enhanced through CloudTrail, AWS Config, and VPC Flow Logs, providing visibility into API activity, configuration changes, and network traffic.
Encryption was implemented across the environment using AWS Key Management Service (KMS) with customer-managed keys, covering storage, databases, logs, and backups. Network security was strengthened through VPC isolation, private subnets, and security group restrictions.
In parallel, OneData helped Sistemas to migrate its on-premises SQL Server 2016 database to Amazon RDS for SQL Server (2017 Express Edition) using AWS Database Migration Service (DMS). The migration was executed using a full-load approach with validation to ensure data integrity. The target environment was configured with encryption at rest, automated backups, restricted network access, and logging aligned with CIS compliance requirements.
Outcome | Improving Security, Compliance, and Operational Efficiency
Following the implementation, Sistemas achieved significant improvements in security, compliance, and operational efficiency.
