臺灣與大陸關係政策日新月異變遷，使得兩岸之間的交流日漸頻繁，現階段看似良性互動的發展，不僅以維護兩岸的和平為方向，更活絡了經濟貿易及歷史性的新格局，然不容否認的，在兩岸關係的發展中，臺灣民眾敵我意識亦有所懈怠，恐造成敵人各項滲透、顛覆活動的良好時機。而敵人一切滲透、分化、破壞陰謀，多以國家公務機密為首要目標，足見機密資訊維護在國家上之重要性，非得有完善的風險預防作為，以獲致良好的機密資訊防護效果，更是未來各部門、機關精進方向。本研究係統計2002至2015年全國各法院審理國家公務機密犯罪案件，就司法院法學資料檢索系統裁判書及各媒體報導裁決內容計24件與相關參考文獻歸納，並以作業風險管理軟體(ORMIT)針對政府機關內負責防範公務機密資訊、維護或公務機密資料管理案件專家，進行風險評估問卷調查，並以維護國家公務機密失效機制中可能存在的風險因子進行分析整理，並加以評估危險幅度、機率及評定風險等級，研究發現公務機密洩漏對於政治、經濟、國防、社會及外交安全有著重大的影響，建議強化接觸機密人員管控、提升法規刑責防範洩密與定期實施作業風險評估等具體作法，供政府相關單位實務運作提高國家公務機密維護並降低風險參考。

The problem of cross-straits hostility has yet to be solved. Since declaring an end to martial law on July 15, 1987, Taiwan has been following international economic trends and cross-strait exchanges have been increasing. After governmental policy adjustments, Taiwan has attracted many visitors, spouses, students, investments, and businesses from mainland China. Despite the seemingly reduced level of cross-straits hostility, mainland China has yet to renounce the use of force against Taiwan. Instead, mainland China has been interacting with the people of Taiwan in a variety of other ways, which has led to an increasingly complacent attitude with respect to the protection of confidential information and counter-espionage. At the same time, concealed enemies are already performing infiltrations and stealing confidential data. This study conducted a statistical analysis of the trial proceedings of official secret leakage cases that were reported nationwide over 2002-2015. The analysis included 24 court verdicts registered in the Law and Regulations Retrieving System of the Judicial Yuan, Taiwan, and rulings reported in media, and related literature. Operational Risk Management Integration Tools (ORMIT) were used to conduct a risk assessment questionnaire survey among governmental officials responsible for the prevention and protection of official secrets leakage and the management of official secret information. Furthermore, potential risk factors for the failure of official secret leakage prevention were analyzed, including an evaluation of risk scope, probability, and level. This study found that official secret leakage had a major impact on political, economic, national defense, social, and diplomatic security. It is recommended that secret-related personnel management should be enhanced, leakage-related criminal liability should be increased, and operations should be subjected to risk assessments on a regular basis. This study provided related units with a reference for the reduction of leakage risks in practical operations.
