ISO 28004-2:2014 identifies supply chain risk and threat scenarios, procedures for conducting risks/threat assessments, and evaluation criteria for measuring conformance and effectiveness of the documented security plans in accordance with ISO 28000 and the ISO 28004 series implementation guidelines. An output of this effort will be a level of confidence rating system based on the quality of the security management plans and procedures implemented by the seaport to safeguard the security and ensure continuity of operations of the supply chain cargo being processed by the seaport. The rating system will be used as a means of identifying a measurable level of confidence (on a scale of 1 to 5) that the seaport security operations are in conformance with ISO 28000 for protecting the integrity of the supply chain.
