Now source files handling is delegated to functions defined in `sourcefs.c` file. By encapsulating methods for managing the underlying source files structure we ensure that all code changes to the source file protection strategy will be localized to `sourcefs.c` file. Also changed Makefile to use more sane way of handling options and build flags. |

ICFS -- Interactively Controlled File System
Motivation
Traditional access control mechanisms in operating systems allow the same level of access to all processes running on behalf of the same user. This typically enables malicious processes to read and/or modify all data accessible to the user running a vulnerable application. It can be dealt using various mandatory access control mechanisms, but these are often complicated to configure and are rarely used in common user oriented scenarios. This thesis focuses on design and implementation of a file system layer which delegates the decision to allow or deny access to a file system object by a specific process to the user.
Goals
- Analyze the problem and design a solution
- Implement the solution using the FUSE framework
- Test the solution and demonstrate its benefits
