Security

This page covers the current Redox security mechanisms.

• Redox have namespaces and a capability-based system, both are implemented by the kernel but some parts can be moved to user-space.
• A namespace is a list of schemes, if you run ls :, it will show the schemes on the current namespace.
• File descriptors are a form of capabilities.

Sandbox

Redox allows limiting a program's capabilities and thus allows sandboxing, by:

• 1 - by only putting a certain number of schemes in the program's namespace, or no scheme at all, in which case new file descriptors can't be opened.
• 2 - by forcing all functionality to occur via file descriptors (it's not finished yet)
