摘要

受惠於網路科技進步，各國之間對話、交流、貿易等活動擴大了全球物品的流動。維持國家內部穩定運作的關鍵基礎設施，也連帶提供非常便利的服務，包括電力、水力、交通以及金融體系，而數位化的關鍵基礎設施，成為促進經濟繁榮、強大軍事力量、政府施政透明度的重要基石。然而日益依賴網路的同時，可能因為網路科技產生漏洞，使得國家安全面臨挑戰。美國了解網路安全挑戰，影響層面涵蓋軍事領域、經濟、民生，甚至國際事務等，將網路安全問題視為重要的威脅來源之一。本文分析美國應對網路安全威脅實踐過程，探討網路安全對於美國的意義，歸納美國目前面臨的網路安全威脅趨勢；另外也體認出美國應對網路安全威脅的防護經驗，計有「邁向組織創新」、「提升政府部門與私人企業合作」，以及「強化情報與反情報工作」等三項；最後強調借鏡美國網路安全防護經驗，進而建立「完善之前瞻性戰略」與建構「安全工作的新穎情境」等作為，有助於提升我國網路安全效能。

Information technology has enhanced international dialogue, exchange and trade and facilitated global flow of goods and services. Key infrastructures which withhold internal stability and operation of country provide convenient services including electricity, water, transportation and financial system. Digitalized infrastructures can promote economic prosperity, strengthen military capability, and enhance the transparency of government. Nevertheless, while the world is increasingly relying on cyberspace, it is likely that loopholes can be generated along with the development of information technology. Thus, key infrastructures can be devastated by cyber attacks and pose great challenges to national security. The US acknowledge the scope of cyberspace challenges which covers the fields of military, economy, livelihood, and even international affairs. The cyber security has also been considered as one of the most serious threats to national security. Through the practicing process for tackling the challenges of cyber security, this article analyzes the implications of cyber security to the US, and generalizes the trend of cyber threats that the US is currently facing. Secondly, it illustrates the experiences of how America protects its cyber security, including innovation of organization, promotion of public-private partnership, and strengthening the efforts of intelligence gathering and counter-intelligence efforts. Finally, it is worth learning the lessons from American's cyber security protection in order to establish a comprehensive and forward-thinking strategy and to build new circumstances for security works. These efforts are able to enhance the efficacy of Taiwan's security works so national security can be ensured.
