.... of COTS items is to use black box testing together with system level fault and operational system [Voas98] However, the effectiveness of black box testing to achieve high levels of integrity is questionable and more rigorous testing generally requires knowledge of design and source code structure [Scott]. A particular problem is determining the total functionality of the COTS item to test [McDermid98] 4.4 Using Empirical Evidence Some standards such as DO 178B [Std178B] and IEC 61508 [Std61508] allow assurance to be generated from empirical evidence such as operational use. Where it is ....

....the hazards. This step is necessary even after hazards have been identified and controlled through design, in order to determine if any mistakes were made in the safety engineering process. Safety verification includes both static and dynamic analysis, such as system testing and code inspections [SL94], as well as software fault tree analysis [LCS91] and formal verification techniques [Bar97] Process checks are conducted to ensure that the hazard mitigations identified in the earlier stages of development have been implemented. Final system risk assessment is performed to ensure that the risks ....
