About the Customer
Sistemas is a Mexico-based technology solutions provider focused on delivering IT infrastructure, cloud, and digital transformation services. The company supports organizations in modernizing operations through scalable and secure technology platforms designed to improve operational efficiency, reliability, and long-term business growth.
Overview
As part of its cloud modernization initiative, Sistemas identified the need to strengthen security governance across its AWS environment while modernizing its legacy SQL Server infrastructure.
The existing environment presented operational and security challenges related to inconsistent encryption practices, manual credential management, limited audit visibility, and fragmented monitoring capabilities. In addition, the organization’s on-premises SQL Server 2016 environment required modernization to improve scalability, resilience, and operational efficiency.
To address these requirements, Sistemas partnered with OneData to implement AWS-native security controls, automated governance frameworks, centralized monitoring, and database modernization using Amazon RDS and AWS Database Migration Service (AWS DMS).

Opportunity | Strengthening Security Visibility and Reducing Operational Risk
Sistemas identified multiple operational and security risks within its existing environment that increased the complexity of maintaining secure and compliant cloud operations.
The organization lacked centralized monitoring and audit visibility across workloads, limiting the ability to continuously monitor activity, validate configurations, and identify potential exposure risks. Manual IAM access key management increased the risk of credential exposure, while inconsistent encryption practices created gaps in data protection and compliance alignment.
Security visibility across workloads was also limited, making it difficult to identify external access risks, monitor API activity, assess vulnerabilities, and detect anomalous behavior across the environment.
At the same time, the organization’s legacy SQL Server 2016 infrastructure required modernization to address scalability, maintenance, and security requirements while supporting long-term operational resilience.
These challenges highlighted the need for a structured security and governance framework capable of improving monitoring visibility, automating remediation processes, strengthening identity and access controls, and modernizing the database environment using AWS-native services.
Solution | Implementing AWS-Native Security Controls and Database Modernization
To address these challenges, Sistemas partnered with OneData to implement a structured AWS-native security and governance framework while modernizing its legacy database infrastructure.
Identity and access management controls were strengthened through enhanced password policies, automated IAM access key rotation, and least-privilege validation processes. AWS Lambda was implemented to automatically detect and rotate IAM access keys older than 90 days, while Amazon SNS notifications and centralized Amazon S3 logging supported audit visibility and operational monitoring.
To improve security monitoring and investigation visibility, AWS CloudTrail, AWS Config, AWS Security Hub, and IAM Access Analyzer were deployed to continuously monitor API activity, validate configurations, identify external access risks, and centralize security findings across the environment.
Security findings, audit logs, and operational telemetry were continuously reviewed through centralized monitoring workflows to support incident investigation, operational analysis, and coordinated remediation activities across the AWS environment.
Amazon GuardDuty, Amazon Inspector, and Amazon Macie were implemented to strengthen threat detection, vulnerability assessment, and sensitive data protection capabilities. Monitoring visibility was further enhanced through VPC Flow Logs, DNS log monitoring, and anomaly detection capabilities, enabling improved visibility into network traffic patterns, workload activity, and configuration changes across AWS accounts.
Event-driven alerting and operational escalation workflows were implemented to improve visibility into high-priority security findings and support continuous operational monitoring activities aligned with AWS security best practices.
Security remediation and hardening activities included eliminating unintended public access risks, implementing VPC isolation and private subnets, enforcing security group restrictions, enabling encryption by default, and automating governance controls to reduce manual operational effort.
Encryption controls were implemented across workloads using AWS Key Management Service (AWS KMS) with customer-managed keys covering Amazon RDS, Amazon S3, EBS volumes, CloudTrail logs, backups, and supporting services.
In parallel, OneData helped Sistemas migrate its on-premises SQL Server 2016 database to Amazon RDS for SQL Server using AWS Database Migration Service (AWS DMS). The migration was executed using a full-load migration approach with validation processes designed to maintain data integrity and operational continuity throughout the transition.
The target database environment was configured with encryption at rest, automated backups, restricted network access, centralized logging, and compliance-aligned governance controls to support long-term scalability and operational resilience.
