Userspace Administrative Tools

For LinSec to represent a fully functional package a complete set of userspace tools to manage the mandatory security policy has to be provided. Due to the time constraints, LinSec userspace tools have been regarded as an external element from the project onset. However, LinSec provides interface to userspace via config files and /proc file system (Section 5.3). The interface implemented is complete and provides functionality for manipulating any of the aspects of LinSec mandatory security policy specified in Chapter 4, Section 4.5. The exclusion of the userspace tools from the project does not hamper its academic value but it severely impacts LinSec acceptance in the real world. As one of the aims of LinSec was that it should represent a practical system the decision was made to allow external development of the tools according to the strict interface specification. Userspace tools were, therefore, implemented by Mr Bosko Radivojevic and Mr Veselin Mijuskovic at the Computer Centre, Faculty of Electrical Engineering, University of Belgrade.
