Identity management

The master thesis is divided into two parts. In the first part, identity management is described on theoretical basis. Particular domains of identity management including authentication, authorization and audit are explained as well as Single Sign-On concept, i.e. using single credentials and entering them just once for access to multiple independent systems or services. In the second part, which forms the main part of this thesis, a practical project was implemented on the infrastructure of the Department of Telecommunications within the Faculty of Electrical Engineering and Communication, Brno University of Technology. The goal of this project was to create an environment for central 4 authentication and Single Sign-On using only open source technologies within a computer laboratory used for teaching OS Linux. The project is based on OS Linux Debian, Kerberos as a protocol for secure authentication and LDAP server OpenLDAP. For the Single Sign-On demonstration, NFS services for accessing data on the network were chosen. Using NFS services, users can sign-on to any workstation and access all their data. Administration of users and their import from central FEEC databases was implemented using scripts developed in Python. Next, using Apache, PHP and MySQL, a front-end audit interface for the network administrator was developed in order to inspect and evaluate security events in the network. Messages about suspicious events are delivered to administrator’s mailbox in real time. The project is intended as a security platform which means that other services can be implemented for Single Sign-On as well as new mechanisms for evaluation of suspicious events
