Process isolation can be implemented with virtual address space, where process A's address space is different from process B's address space – preventing A from writing onto B. Security is easier to enforce by disallowing inter-process memory access, in contrast with less secure architectures such as DOS in which any process can write to any ...
Site isolation is a web browser security feature that groups websites into sandboxed processes by their associated origins. This technique enables the process sandbox to block cross-origin bypasses that would otherwise be exposed by exploitable vulnerabilities in the sandboxed process.
Examples of isolation groups include the main steamlines, the reactor water cleanup system, the reactor core isolation cooling (RCIC) system, shutdown cooling, and the residual heat removal system. For pipes which inject water into the containment, two safety-related check valves are generally used in lieu of motor operated valves.
Emergency core cooling systems (ECCS) are designed to safely shut down a nuclear reactor during accident conditions. The ECCS allows the plant to respond to a variety of accident conditions (e.g. LOCAs ) and additionally introduce redundancy so that the plant can be shut down even with one or more subsystem failures.
Intel Software Guard Extensions (SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). ). They allow user-level and operating system code to define protected private regions of memory, called encla
A major field of application for SR-IOV is within high-performance computing (HPC). The use of high-performance InfiniBand networking cards is growing within the HPC sector, and there is early research into the use of SR-IOV to allow for the use of InfiniBand within virtual machines such as Xen.
The flyback converter can be viewed as two inductors sharing a common core with opposite polarity windings. In contrast, the forward converter (which is based on a transformer with same-polarity windings, higher magnetizing inductance, and no air gap) does not store energy during the conduction time of the switching element — transformers ...
Isolation testing may also be conducted between one or more electrical circuits of the same subsystem. [1] The test often reveals problems that occurred during assembly, such as defective components , improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical ...
