Secure management of information is becoming critical for any organization because information is one of the most valuable assets in organization’s business operations. An Information security management system (ISMS) consists of the policies, procedures, guidelines, and associated resources and activities, collectively managed by an organization, in the pursuit of protecting its information assets. An ISMS is a systematic approach for establishing, implementing, operating, monitoring, reviewing, maintaining and improving an organization’s information security to achieve business objectives. Consequently, it is difficult to do all tasks in ISMS without any support tools. In this thesis we will try to present an appropriate toolkit identifying software supportable tasks in ISMS life cycle process. This toolkit will become the basis for organizations who wants to implement and maintain their ISMSs.
