SEFlow facilitates the utilization of SELinux to manage the flow of data within an information processing system.
SEFlow is a remarkable software that leverages the SELinux technology to control the flow of data within an information processing system. Unlike the conventional SELinux policies that primarily focus on governing access to static system facilities, such as a system logger or an httpd, SEFlow is designed to secure the data itself, which is subject to dynamic changes in its positioning within the system.
One of the standout features of SEFlow is its mathematical policy model, which enables it to model the policy using mathematical primitives. By combining small sub-policies through operations like unions, intersections, and cartesian products, SEFlow provides a more orthogonal approach to policy design.
SEFlow finds possible application in license management, particularly in a large-scale development environment where data is subject to licenses with varying terms and conditions. To track different licenses, SEFlow allows for the addition of licensing information to the security context of files. The operating system kernel can thus determine the licensing conditions that apply to the resulting data, helping to ensure compliance.
Another significant advantage of SEFlow is the strategic approach to security it provides, which can be attributed to the licensing mechanism as described earlier. Through this mechanism, critical system facilities can be limited from interference by open-source data, improving the potential for identifying and resolving any issues that may arise.
It is essential to note that the applications mentioned above are not yet possible as the SEFlow project is still in the prototyping phase, serving as a technology demo. However, users can experiment with the existing code and create a minimal policy that may not provide any security yet can be extended.
Notably, SEFlow requires users to have NSA Security-enhanced Linux installed to work. In the latest update, a new feature has been added to demonstrate the possibility of combining independent policy factors. This factor blocks network access to processes, disabling it without interfering with other constraints, such as licensing or other security policies.
