42、ion) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to

43、deal with particular fields of technical activity. ISO and IEC technical committees 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

44、 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 by t

45、he joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

46、rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 27035 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 27, IT Security techniques. This first edition of ISO/IEC 27035 cancels and replaces ISO/IEC

47、 TR 18044:2004, which has been technically revised.

48、 After controls have been implemented, residual vulnerabilities are likely to remain that can make information security ineffective and thus information security incidents possible. This can potentially have both direct and indirect adverse impacts on an organizations business operations. Further, i

49、t is inevitable that new instances of previously unidentified threats will occur. Insufficient preparation by an organization to deal with such incidents will make any response less effective, and increase the degree of potential adverse business impact. Therefore, it is essential for any organization serious about information security to
