Off-road vehicle drivetrains. Later, during the 1990s, manufacturers started to add even more luxuries to bring those off-road vehicles on par with regular cars. This eventually evolved into what we call the SUV today. It also evolved into the newer crossover vehicle, where utility and off-road capability was sacrificed for better on-road handling and luxury. To be able to drive off the pavement, off-road vehicles need several characteristics: They need to have a low ground pressure, so as not to sink into soft ground, they need ground clearance to not get hung up on obstacles, and they need to keep their wheels
Capability-based security with the UNIX design and POSIX API. Capsicum capabilities are a refined form of file descriptor, a delegable right between processes and additional object types beyond classic POSIX, such as processes, can be referenced via capabilities. In Capsicum capability mode, processes are unable to utilize global namespaces (such as the filesystem namespace) to look up objects, and must instead inherit or be delegated them. Notable research and commercial systems employing capability-based security include the following: POSIX "capabilities" in Linux: Capability-based security Capability-based security is a concept in the design of secure computing systems, one of the existing security models.
