Distributed Ledger Technology To Enable Secure Management of It Infrastructures

IT Infrastructures have grown in both size and complexity. To help administrators to manage their infrastructure, several Infrastructure Management Tools have been created. However, none of them implements a secure a traceable log of changes that can bring accountability to the management of such infrastructures. On the other hand, recent research and development in blockchain technologies have allowed for the creation of Distributed Ledgers that can, in theory, solve the problem by providing a secure, immutable and traceable ledger that can store the changes that the infrastructure management tools apply to de infrastructure. In this Thesis, we develop a proof-of-concept solution that incorporates a Distributed Ledger, Hyperledger Fabric, and infrastructure management tools, Ansible and Terraform, to prove the suitability of the usage of a distributed ledger to provide a secure inventory and log of changes in a manner that enables for traceability and accountability for all modifications to the infrastructure, while also providing user identity management.
