One of the most important international developments for defining security behavior has been the adoption of the international standard ISO 17799 Code of Practice for Information Security Management. It is a comprehensive management standard for addressing the full range of issues for protecting information. Sensible adoption and application of the standard could provide significant benefits both to business and consumers. Self regulation schemes would do well to consider adopting it as a means of providing a common frame of reference for security and privacy claims.
