Multi-Agent Systems (MASes) are commonly used in many computing services. Hence, security aspects of these services should be guaranteed, especially, if the services are related to critical tasks. The evaluation methods of MASes security should report the security concerns. This paper introduces a general approach for evaluating the security of an agent in MAS environments. The proposed framework is based on Goal/Question/Metric (GQM) approach combined with fuzzy logic. It generates the GQM structure of the agent security. Then, fuzzy logic controllers are utilized to measure the security of the agent. The performance of the proposed method is measured in percentage of satisfying a set of security criteria. Experimental studies are conducted to evaluate the strengths and the weaknesses of MAS security aspects such as confidentiality, authentication, repudiation, and access control. Finally, the proposed framework is applied to a case study and the results are assessed.
