  2. Software safety - Wikipedia

    en.wikipedia.org/wiki/Software_safety

    Software safety (sometimes called software system safety) is an engineering discipline that aims to ensure that software, which is used in safety-related systems (i.e. safety-related software), does not contribute to any hazards such a system might pose. There are numerous standards that govern the way how safety-related software should be ...

  3. Risk-based testing - Wikipedia

    en.wikipedia.org/wiki/Risk-based_testing

    Risk-based testing (RBT) is a type of software testing that functions as an organizational principle used to prioritize the tests of features and functions in software, based on the risk of failure, the function of their importance and likelihood or impact of failure. [1] [2] [3] In theory, there are an infinite number of possible tests.

  4. Software assurance - Wikipedia

    en.wikipedia.org/wiki/Software_Assurance

    Software assurance (SwA) is a critical process in software development that ensures the reliability, safety, and security of software products. [1] It involves a variety of activities, including requirements analysis, design reviews, code inspections, testing, and formal verification.

  5. Safety integrity level - Wikipedia

    en.wikipedia.org/wiki/Safety_integrity_level

    Assignment, or allocation of SIL is an exercise in risk analysis where the risk associated with a specific hazard, which is intended to be protected against by a SIF, is calculated without the beneficial risk reduction effect of the SIF. That unmitigated risk is then compared against a tolerable risk target.

  6. Hazard analysis - Wikipedia

    en.wikipedia.org/wiki/Hazard_analysis

    When software is involved in a system, the development and design assurance of that software is often governed by DO-178C. The severity of consequence identified by the hazard analysis establishes the criticality level of the software. Software criticality levels range from A to E, corresponding to the severity of Catastrophic to No Safety Effect.

  7. Failure mode, effects, and criticality analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_Mode,_Effects,_and...

    Failure Modes, effects, and Criticality Analysis is an excellent hazard analysis and risk assessment tool, but it suffers from other limitations. This alternative does not consider combined failures or typically include software and human interaction considerations. It also usually provides an optimistic estimate of reliability.

  8. Software security assurance - Wikipedia

    en.wikipedia.org/wiki/Software_Security_Assurance

    Software security testing, which includes penetration testing, confirms the results of design and code analysis, investigates software behaviour, and verifies that the software complies with security requirements. Special security testing, conducted in accordance with a security test plan and procedures, establishes the compliance of the ...

  9. Safety life cycle - Wikipedia

    en.wikipedia.org/wiki/Safety_life_cycle

    This article uses software as the context but the safety life cycle applies to other areas such as construction of buildings, for example. In software development, a process is used (software life cycle) and this process consists of a few phases, typically covering initiation, analysis, design, programming, testing and implementation.
