Criteria Definition and 87 Threads

The Common Criteria for Information Technology Security Evaluation (referred to as Common Criteria or CC) is an international standard (ISO/IEC 15408) for computer security certification. It is currently in version 3.1 revision 5.Common Criteria is a framework in which computer system users can specify their security functional and assurance requirements (SFRs and SARs respectively) in a Security Target (ST), and may be taken from Protection Profiles (PPs). Vendors can then implement or make claims about the security attributes of their products, and testing laboratories can evaluate the products to determine if they actually meet the claims. In other words, Common Criteria provides assurance that the process of specification, implementation and evaluation of a computer security product has been conducted in a rigorous and standard and repeatable manner at a level that is commensurate with the target environment for use. Common Criteria maintains a list of certified products, including operating systems, access control systems, databases, and key management systems.

    Safety margin to acceptance criteria

    10 CFR 50.46 gives the acceptance criteria as the required condition for the performance of ECCS. There, it is indicated that PCT (Peak Clad Temperature) must be below 2200F. On the other hand one can rarely find an accident analysis for NPPs with the result of the analysis showing the PCT...

    Convergence criteria for fixed point iteration

    Homework Statement Most functions can be rearranged in several ways to give x = g(x) with which to begin the fixed-point iteration method. For f(x) = e^x − 2x^2 , one g(x) is x = +- sqrt(e^x/2) a) Using the convergence criteria, show that this converges to the root near 1.5 if the positive...

    Quotient criteria and the harmonic series
