IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems.
Should the risk assessment establish that the required SIL cannot be achieved by a SIL4 SIF, then alternative arrangements must be designed, such as non-instrumented safeguards (e.g, a pressure relief valve). [1] There are several methods used to assign a SIL. These are normally used in combination, and may include: [1] Risk matrices; Risk graphs
End-user computing (EUC) refers to systems in which non-programmers can create working applications. [1] EUC is a group of approaches to computing that aim to better integrate end users into the computing environment. These approaches attempt to realize the potential for high-end computing to perform problem-solving in a trustworthy manner.
IEC standard 61511 is a technical standard which sets out practices in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation. Such systems are referred to as Safety Instrumented Systems .
This concept is taught to managers in industry, to be promoted as standard practice in the workplace. It has also been used to inform public policy, in fields such as road safety. [13] Various illustrations are used to depict this system, most commonly a triangle. The hazard controls in the hierarchy are, in order of decreasing priority ...
Automotive Safety Integrity Level (ASIL) is a risk classification scheme defined by the ISO 26262 - Functional Safety for Road Vehicles standard. This is an adaptation of the Safety Integrity Level (SIL) used in IEC 61508 for the automotive industry. This classification helps defining the safety requirements necessary to be in line with the ISO ...
Risk control, also known as hazard control, is a part of the risk management process in which methods for neutralising or reduction of identified risks are implemented. . Controlled risks remain potential threats, but the probability of an associated incident or the consequences thereof have been significantly red
DREAD is part of a system for risk-assessing computer security threats that was formerly used at Microsoft. [1] It provides a mnemonic for risk rating security threats using five categories. Categories
