RSBAC (Rule Set Based Access Control) is a kernel patch which adds several mandatory access models to the Linux kernel. These models can be used to enhance the security of a Linux system.
RSBAC’s main concept is modularity. It uses several well-known and new security models, including Mandatory Access Control (MAC), Access Control List (ACL), PaX and Role-Compatibility (RC) and others.
RSBAC has control over individual users and program network accesses using any combination of the possible security models. It is also highly extensible.
- Independent of governments and big companies.
- Several well-known and new security models, e.g. MAC, ACL and RC.
- On-access virus scanning with Dazuko interface.
- Detailed control over individual user and program network accesses.
- Fully access controlled kernel level user management.
- Any combination of security models possible.
- Easily extensible: write your own model for runtime registration.
- Support for latest kernels.
- Stable for production use.
- Read-only mode (no attribute writing, for testing).
- Transactions support (policy changes can be made atomically).
- Generic list based attributes (objects attributes from all models are stored into hashed, generic lists).
- In kernel user management (no more /etc/passwd).
- Network control support.
- Pseudonymous logging (for privacy concerns).
- Extensive logging capabilities.
- Symlink redirection (symlinks can redirect to another location by role, by uid, by security level or by remote address).
- Disable Linux DAC (be sure to convert them with provided tool to RSBAC ACL first).
- Secure delete (mandatory secure deletion per file, directory or whole filesystem).
- Hide processes easily with a kernel option.
- Freeze mode (no RSBAC setting can be changed until reboot).
- Softmode (RSBAC running in non-enforcing mode, can be disabled per single boot).
- X11 Support.
- Inherited attributes (easy administration).
- Fast, low overhead solution.
- TTL, define certain accesses at certain dates/time only.
- Highly portable.
