4. Enabled code quality measurement.

We automated the performance of unit and integration tests, integrated SonarQube for code quality checks.

5. Ensured system stability:

By building advanced monitoring and centralized application logging.

6. Automated daily operations:

Such as backups, Docker images clean-ups and others.

7. Configured VoIP telephony

Using FreePBX running in Docker as solution VoIP telephony.

platform for electronic legally binding signatures. To safely store private keys they needed to use a highly secure and HIPAA-compliant Hardware Secure Module (HSM) provided by Amazon (AWS CloudHSM). The deployment and configuration of the service, as well as the creation of properly secured private keys and integration of applications with HSM are not some easy tasks. Greg Solutions applied our extensive experience to support the customer every step of the way, starting from the configuration of CloudHSM till the generation of a proper CSR (certificate signing request) for the Certificate Authority (CA) and integration of the application with CloudHSM using the Client HSM daemon, HSM SDK and Java libraries and providers, such as iText and Cavium.  

 

Goals: 

1. Deploy and configure AWS CloudHSM clusters for multiple environments to securely store private keys. 

2. Pass the workflow of generating non-exportable private keys to retrieve a certificate from the certificate authority.

3. Enable the automation of document signatures using the Java/iText library and private keys from CloudHSM.

4. Provide comprehensive documentation and support for the client’s development team to help them migrate the system from the hardware HSM to AWS CloudHSM.

 

Results:

1. Deployed Cloud HSM clusters:

Deployed and configured highly secure AWS CloudHSM clusters in multiple AWS environments using Terraform for the initial steps. 

2. Connected Java Web API server and Cloud HSM:

Implemented a Java Web API server that interacts with CloudHSM using PKCS 12, the iText library and Cavium providers and helps to securely sign user documents.

3. Document the Cloud HSM setup and configuration:

Provided the documentation helping to deploy, configure and connect applications to the highly secure AWS CloudHSM clusters 

4. Ensured system stability: 

Added Cloud HSM monitoring using AWS Cloud Watch

5. Provided maintenance & troubleshooting support: 

Supported the client’s development team, assisted with the system’s configuration, debugging and troubleshooting.
