Capstone Project Outline:

Secure & Scalable AI-Powered Chatbot with Enhanced Security and Advanced Features

The goal behind this capstone project is not to solve a specific problem but to find new problems to solve and to learn new things in the process.

1. Introduction

  • 1.1 Project Background:
    • I am technically savvy in networking, compute, python, Linux, AWS, virtualization, cybersecurity with experience in using python with API calls to Generative AI including; open-ai, Gemini, and AWSs Bard. I would like to challenge myself with a custom (made for me) capstone project that focuses on AI, docker, cybersecurity, and includes single sign on, and my experience with AWS public cloud, python and Linux.
    • Highlight the importance of security, scalability, and user experience in chatbot development.
    • How to create a containerized, Internet accessible chatbot, behind a secure, SSO with MFA website, leveraging my knowledge of Python, API, LLM, AWS, Docker and extending my understanding of LLM training, custom models, TensorFlow and RAG. Stretch goal to include multi-cloud docker environment and include GPU based hardware with TensorFlow integration.
    • Learn new things durring the process of development.
  • 1.2 Problem Statement:
    • How to create, a containierized Define the challenges and limitations of existing chatbot solutions, such as security vulnerabilities, limited scalability, and inadequate user experience.
  • 1.3 Project Objectives:
    • Develop a secure and scalable AI-powered chatbot application with enhanced features.
    • Implement robust security measures, including SSO, 2FA, and secure access controls.
    • Integrate advanced features like RAG, file uploads, and a user-friendly web interface.
    • Deploy the chatbot on a cloud platform (AWS) for scalability and reliability.

2. Literature Review

  • 2.1 AI Chatbot Technologies:
    • Discuss the evolution of chatbot technologies, including rule-based systems, machine learning models, and large language models (LLMs).
    • Explore different types of LLMs and their applications.
  • 2.2 Security Best Practices:
    • Review security principles and best practices for web applications, including authentication, authorization, data encryption, and vulnerability management.
    • Discuss the importance of SSO, 2FA, and access control in enhancing security.
  • 2.3 Cloud Computing Technologies:
    • Explore relevant AWS services (e.g., ECS, EKS, Lambda, S3) and their suitability for deploying and scaling chatbot applications.
  • 2.4 RAG Architectures:
    • Discuss the concept of Retrieval Augmented Generation (RAG) and its benefits for improving chatbot performance and accuracy.

3. Methodology

  • 3.1 System Design:
    • Design the overall system architecture, including components such as:
      • Frontend (Web Interface)
      • Backend (API Gateway, Chatbot Logic, Database, etc.)
      • AI Model Integration
      • Security Modules (SSO, 2FA, Authorization)
      • Cloud Infrastructure (AWS services)
    • Create detailed system diagrams and flowcharts.
  • 3.2 Technology Stack:
    • Frontend: Select a suitable frontend framework (e.g., React, Vue.js, Angular).
    • Backend: Utilize Python with frameworks like Flask or Django.
    • Database: Choose a suitable database (e.g., PostgreSQL, MongoDB) for storing user data and chatbot interactions.
    • AI Model: Select and integrate a suitable LLM (e.g., GPT models, Gemini, Bard).
    • Cloud Services: Utilize AWS services for deployment, scaling, and management.
  • 3.3 Development Process:
    • Agile development methodology (e.g., Scrum) with iterative development and testing.
    • Version control system (e.g., Git) for tracking code changes and collaboration.

4. Implementation

  • 4.1 Development:
    • Develop the frontend, backend, and chatbot logic.
    • Integrate the chosen LLM and implement the RAG architecture.
    • Develop and implement security features (SSO, 2FA, access control).
    • Implement file upload and processing functionality.
    • Develop and test the API endpoints.
  • 4.2 Dockerization:
    • Containerize the application and its dependencies using Docker.
  • 4.3 AWS Deployment:
    • Deploy the Dockerized application on AWS using the selected service (e.g., ECS, EKS).
    • Configure and manage the deployment using AWS tools and services.

5. Testing and Evaluation

  • 5.1 Unit Testing:
    • Conduct unit tests for individual components of the application.
  • 5.2 Integration Testing:
    • Test the integration of different components of the system.
  • 5.3 User Acceptance Testing (UAT):
    • Involve users in testing the application's functionality and usability.
  • 5.4 Performance Testing:
    • Evaluate the application's performance under different load conditions.
  • 5.5 Security Testing:
    • Conduct security audits and penetration testing to identify and address vulnerabilities.

6. Results and Discussion

  • 6.1 Project Outcomes:
    • Present the final deployed chatbot application and its key features.
    • Demonstrate the effectiveness of the implemented security measures.
    • Analyze the performance and scalability of the deployed application.
  • 6.2 Discussion:
    • Discuss the challenges encountered during development and how they were addressed.
    • Analyze the strengths and weaknesses of the implemented solution.
    • Discuss the potential for future improvements and enhancements.

7. Conclusion
