摘要

由于不断变化的网络威胁形势,联邦系统不断面临风险。网络威胁可以导致从系统功能退化到数据窃取的任何事情。根据联邦系统的重要性,网络事件可能是灾难性的,给联邦政府造成重大的经济损失,潜在地影响美国公众的隐私或安全,因此被归类为关键基础设施。在过去的一年里,联邦制度的现代化得到了很多关注。2017年,总统行政办公室完成了一份关于联邦IT现代化的报告[1],以及关于加强联邦网络和关键基础设施网络安全的总统行政命令[2]。在许多情况下,联邦关键基础设施通常由遗留系统组成,遗留系统由老化的技术、程序语言或硬件组成。随着时间的推移,遗留资产的维护和运营成本将继续增加,并且随着过时的技术变得过时或不受支持而变得更加难以保护。遗留技术的存在也可能限制采用新功能的能力。为了解决这些问题,联邦机构必须通过现代化逐步减少遗留资产的使用。《2017年政府技术现代化法案》(MGT法案)于2017年5月17日由众议院通过,并于2017年12月12日通过成为法律。2017年的MGT法案是两党共同努力的结果,它要求各机构对其老化的系统进行现代化改造。MGT法案建立在《联邦IT采购改革法案》(FITARA)的基础上,创建了FITARA记分卡,这是一个用于监控联邦机构现代化工作并授权首席信息官采取行动的评分系统。该分数是根据CIO绩效、风险管理、数据中心优化等因素计算得出的。在2017年11月发布的最新FITARA记分卡中,国防部和交通部的得分都是F+。FITARA记分卡提供了对联邦系统现代化现状的洞察;然而,评分系统可能不能完全包含解决关键基础设施(如国家空域系统)面临的挑战所需的考虑因素。

An enterprise cybersecurity strategy for federal critical infrastructure modernization
Federal systems are constantly faced with risks due to the ever-evolving cyber threat landscape. Cyber threats can cause anything from degradation of system functionality to data theft. Depending on the criticality of the Federal system, a cyber-event could be catastrophic, causing a significant financial loss to the Federal government, potentially impacting the privacy or safety of the American public, thus being categorized as Critical Infrastructure. In the past year, modernization of Federal systems has gained much attention. In 2017, The Executive Office of President finalized a report on the Federal IT Modernization [1], as well as the Presidential Executive Order on Strengthening the Cybersecurity of Federal Networks and Critical Infrastructure [2]. In many cases, Federal Critical Infrastructure may often be comprised of legacy systems, which consist of aging technologies, program languages or hardware. The cost of the sustainment and operation of legacy assets will continue to increase over time and become more difficult to protect, as outdated technologies become obsolete or unsupported. The existence of legacy technology may also limit the ability of the adoption of new capabilities. To address these issues, Federal agencies must incrementally reduce the usage of legacy assets through modernization. The Modernizing Government Technology Act of 2017 or MGT Act was passed by the House of Representatives on May 17, 2017, and was recently passed into law on December 12, 2017. The MGT Act of 2017 is a bipartisan effort, which calls for agencies to modernize their aging systems. The MGT Act builds upon the Federal IT Acquisition Reform Act (FITARA), creating the FITARA scorecard, a grading system used to monitor the modernization efforts of Federal agencies and empower CIOs to take action. The score is calculated based on CIO performance, risk management, data center optimization and other factors. In the latest FITARA Scorecard released in November of 2017, both the DOD and DOT scored an F+. The FITARA Scorecard presents insight into the current state of modernization of Federal systems; however, the scoring system may not fully encompass the considerations needed to address the challenges faced by Critical Infrastructure, such as the National Airspace System.
