    • Agenda• Regulatory Compliance• ISO / IEC / JTC-1• ISO 27x Standards Series• ISO 27001 “ The Requirement Standard• SIEM• Compliance Monitoring with SIEM• Summary
    • Regulatory ComplianceRegulatory Compliance is rarely a question of technologybut mostly a question of documenting due process !
    • ISO• ISO (International Organization for Standardization) is the worlds largest developerand publisher of International Standards.• ISO is a network of the national standards institutes of 160 countries, one member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates the system.• ISO is a non-governmental organization that forms a bridge between the public and private sectors. On the one hand, many of its member institutes are part of the governmental structure of their countries, or are mandated by their government. On the other hand, other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.• Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society
    • ISO 27xISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form thespecialized system for worldwide standardization.National bodies that are members of ISO or IEC participate in the development of International Standards through technicalcommittees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technicalcommittees collaborate in fields of mutual interest.Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted bythe joint technical committee are circulated to national bodies for voting. Publication as an International Standard requiresapproval by at least 75 % of the national bodies casting a vote.

    • What is ISO 27001 about ?“….This International Standard has been prepared to provide a model for establishing,implementing, operating, monitoring, reviewing, maintaining and improving an InformationSecurity Management System (ISMS)…..”“…The design and implementation of an organization’s ISMS is influenced by their needs andobjectives, security requirements, the processes employed and the size and structure of theorganization.These and their supporting systems are expected to change over time.It is expected that an ISMS implementation will be scaled in accordance with the needs of theorganization…” Source: ISO/IEC FDIS 27001:2005(E)
