Enhancing System Resilience by 89% and Secure Migration by 87% with AWS

Challenge: Legacy POS system hindered security and operations

The client faced significant security challenges during the modernization of their legacy Point of Sale (POS) system. Built with Java, Hibernate, and an Oracle database backend, the legacy system exhibited inherent security vulnerabilities, making it difficult to manage and protect sensitive data.

The migration process presented several challenges:

Data Security Concerns: Handling sensitive data, including historical transaction records, customer information, and business rules, required stringent security measures to prevent unauthorized access and data breaches during the migration of the legacy POS system to a cloud-based solution.
Migration Complexity: Migrating 8 TB of data from an Oracle database to AWS Aurora PostgreSQL posed complexities in ensuring data integrity and security throughout the transfer.
Legacy System Vulnerabilities: The outdated POS system contained inherent security vulnerabilities that needed to be addressed during modernization to transition to a more secure environment.

Solution: Implementing security measures for cloud-based modernization

Data Encryption: We ensured end-to-end encryption of data during migration and at rest by utilizing AWS Key Management Service (KMS) to securely manage encryption keys, protecting sensitive information from unauthorized access.
Access Controls: We implemented strict access controls using AWS IAM roles and policies, enforcing the principle of least privilege and restricting access to authorized personnel only.
Secure Data Migration: We employed AWS Database Migration Service (DMS) to ensure a secure data transfer process. Tasks were managed at the module level for precise synchronization, incorporating Oracle-side transformations and staging tables to enhance data protection.
Monitoring and Compliance: We utilized AWS CloudTrail and AWS CloudWatch for comprehensive monitoring and logging, facilitating real-time detection of suspicious activities and ensuring compliance with industry security standards and regulations.
