Computer Laboratory: Capsicum: practical capabilities for UNIX
Capsicum is a lightweight OS capability and sandbox framework developed at the University of Cambridge Computer Laboratory, supported by grants from Google, the the FreeBSD Foundation, and DARPA. Capsicum extends the POSIX API, providing several new OS primitives to support object-capability security on UNIX-like operating systems:

capabilities - refined file descriptors with fine-grained rights
capability mode - process sandboxes that deny access to global namespaces
process descriptors - capability-centric process ID replacement
anonymous shared memory objects - an extension to the POSIX shared memory API to support anonymous swap objects associated with file descriptors (capabilities)
rtld-elf-cap - modified ELF run-time linker to construct sandboxed applications
libcapsicum - library to create and use capabilities and sandboxed components
libuserangel - library allowing sandboxed applications or components to interact with user angels, such as Power Boxes.
chromium-capsicum - a version of Google's Chromium web browser that uses capability mode and capabilities to provide effective sandboxing of high-risk web page rendering.
