established security standard ISO/IEC_JTCI11 [4].
The paper is structured as follows: in the section II it will be presented an overview of security management concepts; section III presents the proposed conceptual model, which contains the semantic concepts specified in the information security domain, and their relationships, hierarchical structured in an ontology; section IV presents the proposed framework to manage and audit information systems security, based on the ontology structure; conclusions and future work are presented in section V.

Abstract—Auditing Information Systems Security is difficult and becomes crucial to ensure the daily operational activities of organizations as well as to promote competition and to create new business opportunities. A conceptual security framework to manage and audit Information System Security is proposed and discussed. The proposed framework is based on a conceptual model approach, based on the ISO/IEC_JCT1 standards, to assist organizations to better manage their Information
Systems Security.
Keywords-Security audit management, information system security, ontology and conceptual model.

Speed and accessibility operations promoted by information and communication technologies, particularly the
Internet and the new Internet-enabled services, leads the organizations to become heavily dependent on the performance of their information systems. On the other hand the evolution of wireless communication and the rapid growth and availability of new services to facilitate accessibility, such as, for example, the new cloud computing services, have been gaining popularity not just by the organizations, but by generic users as well. Although these new solutions offer a better service with a promising technological initiatives at low operating cost, they also brings a set of new and
