Elevating Financial Operations & Security with AWS Migration
About the client
A leading financial services firm, aims to migrate its on-premises infrastructure to AWS to enhance security and align with financial industry compliance standards.
The project involves assessing the current infrastructure, deploying AWS landing zone, designing a secure AWS architecture with VPCs, encryption, IAM policies, and threat detection tools like AWS Security Hub and GuardDuty. Multi-AZ deployments, AWS Backup, and disaster recovery plans will ensure high availability, while CloudWatch will enable real-time monitoring.
The migration will minimize downtime, optimize costs, and deliver a secure, scalable environment with comprehensive compliance and operational efficiency.
Existing Challenge:
Scalability Limitations: On-premises infrastructure struggles to scale efficiently to meet fluctuating demands, leading to potential downtime or over-provisioning.
High Maintenance Overheads: Managing and upgrading on-premises hardware and software requires significant time, resources, and costs, impacting overall operational efficiency.
Data Backup and Disaster Recovery Risks: Current backup and recovery processes are not robust or automated, increasing the risk of data loss and prolonged recovery times during failures.
Security Vulnerabilities: The on-premises infrastructure lacks advanced security mechanisms such as automated threat detection, encryption, and centralized access control.
Manual Processes: Dependency on manual operations for scaling, maintenance, and security checks introduces delays and human errors.
Operational Inefficiencies: Manual management of infrastructure leads to delays, higher costs, and reduced operational agility.
Solution
Applications and Databases Migration
- Migrate critical banking systems, including customer-facing portals and internal databases, to AWS using AWS Database Migration Service (DMS) and Application Migration Service.
- Employ encryption for data in transit and at rest to ensure the security of sensitive financial information.
- Validate data integrity and ensure minimal downtime during the migration process.
Secure Connectivity with Financial Partners
- Establish AWS Direct Connect and site-to-site VPN connections to ensure secure and reliable communication with financial partner institutions.
- Use encryption protocols such as IPSec for VPN connections and monitor traffic with VPC Flow Logs to identify potential anomalies.
Landing Zone Implementation
- Deploy a secure AWS Landing Zone using AWS Control Tower to establish a multi-account structure with centralized governance and management.
- Apply guardrails to enforce compliance with financial security standards and automate account provisioning with AWS CloudFormation.
Robust Security Implementation
- Leverage AWS security services like GuardDuty for threat detection, Inspector for vulnerability management, and Config for compliance tracking.
- Implement strict IAM controls with the principle of least privilege and enable multi-factor authentication (MFA) for all accounts.
- Encrypt sensitive financial data using AWS Key Management Service (KMS) and enforce Transport Layer Security (TLS) for all communication.
- Deploy Web Application Firewalls (AWS WAF) and AWS Shield to protect against DDoS attacks.
- Enable logging and monitoring using AWS CloudTrail, Config, and Security Hub to ensure real-time visibility into security events.
- Use AWS Secrets Manager to securely store and rotate sensitive information like database credentials and API keys.
- Enforce network security by designing VPCs with private subnets, Network ACLs, and Security Groups to restrict unauthorized access.
Performance Optimization
- Utilize AWS Dedicated Hosts for EC2 instances to ensure consistent performance of banking applications while meeting compliance and licensing requirements.
- Monitor resource utilization using AWS Trusted Advisor and CloudWatch, and optimize workloads for cost and performance efficiency.
