The objective of this paper is to present an analysis of the importance of computational infrastructures used by IBM WebSphere MQ software for messaging exchange. The traffic of these messages represents a large volume of business with high financial values. The proper treatment of the computational infrastructure allows a higher protection level against malicious software, resulting in proper handling and management of the queue log manager. Since both the involvement of the information security management team and the application of recommendations from ABNT NBR ISO/IEC 27000 standards group make the queue managers infrastructure safer, the result of this work is the definition of the criteria used in the management of environments with IBM WebSphere MQ.
