Description

Sensitive information such as firewall logs or data from intrusion detection systems, has to be stored for long periods of time for legal reasons or for later forensic analysis. With the growth of the sources generating this type of data within a company, it is imperative to find a solution that meets the requirements of scalability, security, availability, performance and low maintenance while keeping the costs under control. Following this need, this project aims to make an analysis of several distributed file systems in order to find a solution that meets both the performance and security requirements of an internal application of Portugal Telecom. To validate the solution, the project includes the design of a prototype that aims to simulate the execution environment of that application.
