Abstract

This thesis focuses on securing company data stored in SaaS storage. In contrast to data stored on-premise, data stored in the cloud face several additional risks, be it from the outside as well as from the inside of the organization. The main risk, whose impacts we try to mitigate in this work, is an accidental data leak by one of the organization's employees. An extension for the Google Chrome web browser was designed and implemented as a solution to this issue. Implementation complications rising from transitioning to a new version of the manifest are also examined in part of this work. The thesis is concluded with the execution of experiments simulating practical data loss scenarios and a verdict on whether a web extension is an appropriate means for creating a tool providing data loss prevention capabilities.
