Securing Intellectual Property, Managing Digital Certificates, and Ensuring Data Security on AWS Cloud Platform.
Feb 2021 - Jul 2022
Business Need
Deutsche Bank's Flow App imperative for a cutting-edge security framework led to a transformative initiative on AWS Focused on intellectual property protection, efficient digital certificate management, and robust data security, the bank's strategic approach ensures a comprehensive safeguarding of sensitive assets. This initiative, titled 'Integrated Security Strategies,' reflects the institution's commitment to innovation, resilience, and the highest standards of confidentiality in its cloud-based operations.
Key Challenges Identified During Assessment:
Regulatory Compliance was first challenge in navigating complex financial regulations.
Integration with Legacy Systems with the new security framework.
Third-Party Integration external entities adhere to high-security standards.
Scalability and Performance Plan for security measures that can scale with the bank's growing operations.
Robust Incident Response Plan was not in place to promptly addressing security incidents.
Data Residency and Sovereignty: Consider global operations, adhering to regional laws and regulations.
Continuous Monitoring and Auditing was not in place for security effectiveness.
Solution Implemented:
- Defined DLP policies to classify and protect sensitive financial data.
- Achieved a 20% reduction in vulnerabilities by implementing robust DLP policies, unified IAM roles, and access controls for securing workloads & certificates, ensuring comprehensive security.
- Enhanced data security by 20% for cloud workloads, utilizing digital certificate management, selecting SSL/TLS certificates, and implementing Certificate Authority Service, ensuring continuous encryption
- Implemented Data Loss Prevention (DLP) with AWS Macie, classifying and securing sensitive financial data in Amazon S3, integrating with third-party DLP tools for enhanced protection.
- Configured IAM policies to enforce least privilege across AWS services (S3, RDS, DynamoDB),
- Established fine-grained access controls on Amazon S3, RDS, and DynamoDB, using Hashi Corp Vault for robust secret management and data access security.
- Set up comprehensive monitoring and alerting with AWS CloudTrail, Guard Duty, and CloudWatch to detect unauthorized access and data exposure, utilizing Splunk for centralized log analysis.
- Automated SSL/TLS certificate issuance and renewal with AWS ACM, using Hashi Corp Vault for additional automation and control across hybrid cloud environments.
- Secured data at rest and in transit with AWS KMS and TLS, applying Thales Cipher Trust for advanced key management and encryption solutions.
- Conducted regular security audits and compliance checks using AWS Config and Security Hub, supplemented with Prisma Cloud for continuous cloud security posture management.
- Documented and communicated encryption and access control procedures with Confluence, maintaining detailed security documentation and ensuring team alignment.
- Developed and executed an incident response plan with AWS Systems Manager Incident Manager, integrating Cortex XSOAR for automated incident handling and response.
