ISO 28004-2:2014根据ISO 28000和ISO 28004系列实施指南，确定了供应链风险和威胁场景、进行风险/威胁评估的程序，以及衡量文件化安全计划合规性和有效性的评估标准。这项工作的一个成果将是一个基于海港实施的安全管理计划和程序质量的信心等级体系，以保障安全，并确保海港正在处理的供应链货物的连续性。评级系统将被用作一种手段，以确定海港安全运营是否符合ISO 28000，以保护供应链完整性的可衡量置信水平（1到5分）。

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.
