Chat Application

 

The Chat Application project, available on GitHub, is a secure, distributed instant messaging application. The project comprises two main components:

  1. chat-application-server :The server manages business logic, user authentication and message management.

    chat-application-desktop :The desktop client provides a user interface for sending and receiving messages in real time.

The development of this application involved the following stages:

  1. Analysis and design of the information system: Definition of functional and technical requirements, and design of the software architecture.
  2.  
  3. Implementation of a secure infrastructure: Use of containerization techniques, implementation of robust encryption protocols and access management to ensure data and communications security.
  4. Microservices architecture development: Creation of independent services to facilitate scalability and application maintenance.
  5. Implementation of an API Gateway and Reverse Proxy: centralized management of requests and secure communications between services via TLS.
  6. Installation of a WAF (Web Application Firewall): Protection against common web threats by filtering and monitoring HTTP traffic.
  7. Security testing: Verification of the application’s resilience against vulnerabilities identified by the OWASP Top 10.
  8. Automating testing and deployment: Using GitLab CI/CD to continuously integrate and deploy the application in the production environment.

This project illustrates our expertise in developing secure applications, integrating security by design and implementing DevSecOps solutions to ensure the quality and security of deliverables.
