Abstract

We design and develop a secret-sharing-scheme-based cyberattack detection model(S3CDM)that can detect unauthorized or illegal activities (especially insider attacks) and protect sensitive information within complex network infrastructures of large organizations. The model splits a secret among a group of legitimate participants or components for authentication, integration and detection of unauthorized activities. Traditional Shamir's polynomial interpolation based and our own hash function based schemes are utilized in the model, they both are practical and efficient to make sure the communications between different components are secure and any unauthorized activities can be detected. The model offers a flexible multi-factor authentication method to enhance the overall system security. Probability analysis [3] shows that multiple component model is more resistant against cyberattacks than the single component one. To demonstrate the feasibility, we implement the S3CDM in three parts on Google Cloud Platform, i.e., the front end UI (User Interface) running on an HTTP server, the back end individual services written in Python, and a PostgreSQL database. Docker is used to manage the start and stop of individual services and their URLs. We demonstrate how to use the UI with a use case of simulation of broken path in details.
