For contemporary software systems, security is considered to be a key quality factor and the analysis of it security risk becomes an indispensable stage during software deployment however, performing risk assessment according to methodologies and standards issued for the public sector or large institutions can be too costly and time consuming. Of fuzzy risk analysis model, development of system architecture, analyzing and designing of the system, building of the prototype, and evaluation of the system an overview of these five stages of system development is shown in figure 1 first, a fuzzy risk analysis model was constructed as the kernel of the system.
Samad hassan basari | | | |[12th april 2011] | software level of security risk analysis using fuzzy expert system abstract there is wide concern on the security of software systems because many organizations depend largely on them for their day-to-day operations. Security risk management is done by the use of srft model, which employs the fuzzy set theory to determine the threats and their countermeasures risk evaluation assesses how much risk to an information system can occur due to a loss event. Security at all stages of software development life cycle (sdlc)in this paper, based on neuro- fuzzy approach software risk prediction tool is created firstly fuzzy inference system is created.
Information security risk analysis methods and research trends: ahp and fuzzy comprehensive such as apply the fuzzy and hierarchy analysis model to network security risk assess research to determine assessment object: define the information system data, hardware, software assets etc, give a system function, borders, critical assets and. Silva, gusmao, poleto, silva, and costa (2014) developed an approach that encompasses failure modes and effects analysis (fmea) and fuzzy theory, and which analyses five dimensions of information security: access to information and systems, communication, infrastructure, security management, and security information systems development. Index terms — fuzzy, qualitative, quantitative, risk assessment, risk analysis, risk assessment technique and threats 1 i ntroduction owever in real world environment, most of organiza- tions do not have proper data about security breaches due to incomplete information or unreported cases. A new lightweight method for security risk assessment based on fuzzy cognitive maps 215 attack perspective within the last couple of years, risk assessment.
Values  virtually every risk element can be characterized using two metrics, “low, medium, and high,” or through“ordinal ranking” [2 ] therefore most appropriate approach for defining risk level is using fuzzy logic in this truth or validity of any statement becomes its degree of belongingness or membership. Neuro-fuzzy based software risk estimation tool keywords : software security, software threat, neural network, fuzzy logic, neuro-fuzzy gjcst-c classification : d29 analysis model is proposed using hidden markov model (hmm), to forecast the cyber threat trend hmm is a tool.
In this section, we will pursue and search between different ideas proposed in literature review with the topic “risk assessment management” including the assessment modeling and we will try to utilize using our risk assessment factors using fuzzy logic 31 risk model currently, many methods are used to identify and prioritize a risk. Similarly, government agencies have used the fuzzy risk evaluation methods (borgman et al, 2015, webster, 1994) for instance, it has been applied to the assessment of risk for the network security which helps to identify the potential threats associated with networking in the government agencies.
Such as apply the fuzzy and hierarchy analysis model to network security risk assess research (, ) the integrated of the analytical hierarchy process, bayesian prioritization procedure. Another application for fuzzy risk assessment presented in  to support the assessment of risk management in network security field for government agencies in this paper, a fuzzy risk assessment system is designed using multi fuzzy inference system mfis to determine the risk rate using factors associated with each risk.
Fuzziness in traditional risk assessment, and create a risk assessment model using fuzzy logic’ fuzzy logic and fuzzy set operations enable characterization of vaguely defined (or fuzzy) sets of likelihood and consequence severity and the mathematics to combine them using expert knowledge, to determine risk. Multicriteria security system performance assessment using fuzzy logic william l mcgill, pe, cre keywords: risk analysis, fuzzy systems, fuzzy logic, probability of adversary success, homeland security 1 introduction software, and human components. Fuzziness in traditional risk assessment, and create a risk assessment model using fuzzy logic’ fuzzy logic and fuzzy set operations enable characterization of vaguely defined (or fuzzy) sets of likelihood and consequence severity and the mathematics to combine them using expert knowledge, to determine risk the fuzzy risk model presented is the first of its kind.
