在兩癌篩查工作數字化進程加速的當下，篩查系統承載著大量個人健康信息與篩查數據，一旦遭遇網絡攻擊或數據泄露，不僅會威脅個人隱私安全，更可能擾亂整個篩查工作的正常秩序。為守護這些關乎生命健康的數據，兩癌篩查系統需從技術防護、制度管理、人員培訓等多維度構建起堅實的安全防線。

　　In the current era of accelerated digitalization of cancer screening work, screening systems carry a large amount of personal health information and screening data. Once they encounter network attacks or data leaks, they not only threaten personal privacy and security, but may also disrupt the normal order of the entire screening work. To safeguard these data related to life and health, the two cancer screening systems need to build a solid security line from multiple dimensions such as technical protection, institutional management, and personnel training.

　　強化技術防護：打造堅不可摧的 “數字堡壘”

　　Strengthening technological protection: building an indestructible 'digital fortress'

　　技術層面的防護是抵御網絡攻擊的首要屏障。首先，兩癌篩查系統需采用先進的加密技術，對傳輸中和存儲的數據進行高強度加密處理。例如，在數據傳輸過程中運用 SSL/TLS 協議，將原始數據轉化為密文，即便數據被截取，攻擊者也難以破解內容；對于存儲在服務器中的篩查報告、患者信息等數據，采用 AES 等成熟的加密算法，配合定期更換密鑰，進一步提升破解難度。同時，部署入侵檢測與防御系統（IDS/IPS）至關重要，該系統能實時監測網絡流量，通過機器學習算法識別異常行為，如惡意掃描、暴力破解、SQL 注入等攻擊手段，并自動阻斷可疑訪問，將威脅拒之門外。此外，定期對系統進行漏洞掃描與修復，借助專業的安全工具檢測系統代碼、服務器配置中的潛在漏洞，及時打上補丁，防止黑客利用已知漏洞發動攻擊。

　　Technical protection is the primary barrier against cyber attacks. Firstly, the two cancer screening systems need to adopt advanced encryption technology to perform high-strength encryption processing on the transmitted and stored data. For example, using SSL/TLS protocol during data transmission to convert raw data into ciphertext makes it difficult for attackers to crack the content even if the data is intercepted; For screening reports, patient information, and other data stored on the server, mature encryption algorithms such as AES are used, combined with regular key replacement, to further enhance the difficulty of cracking. At the same time, it is crucial to deploy intrusion detection and defense systems (IDS/IPS), which can monitor network traffic in real-time, identify abnormal behavior through machine learning algorithms, such as malicious scanning, brute force cracking, SQL injection and other attack methods, and automatically block suspicious access to shut out threats. In addition, regular vulnerability scans and fixes are conducted on the system, utilizing professional security tools to detect potential vulnerabilities in system code and server configuration, and timely patching is applied to prevent hackers from exploiting known vulnerabilities to launch attacks.

　　完善訪問控制：嚴控數據接觸的 “準入門檻”

　　Improve access control: strictly control the "entry threshold" for data access

　　嚴格的訪問控制機制是防止數據泄露的關鍵。兩癌篩查系統應實施最小權限原則，根據工作人員的崗位需求分配不同級別的訪問權限。例如，僅允許數據錄入人員進行篩查數據的錄入操作，禁止其訪問患者完整個人信息；而醫生在查看患者篩查結果時，也需通過二次身份驗證（如動態驗證碼、生物識別），確保操作主體身份真實可信。同時，建立詳細的操作日志記錄系統，對每一次數據訪問、修改、刪除等操作進行全程留痕，記錄訪問時間、操作人員、操作內容等信息。一旦發生數據異常變動，可通過回溯日志快速定位問題源頭，便于追責與整改。此外，針對外部合作機構或臨時訪問需求，需設置嚴格的權限審批流程，明確訪問期限與數據使用范圍，到期后自動收回權限，避免權限濫用導致的數據泄露風險。

　　Strict access control mechanisms are key to preventing data leakage. The two cancer screening systems should implement the principle of minimum privilege and allocate different levels of access privileges based on the job requirements of the staff. For example, only data entry personnel are allowed to perform screening data entry operations, and access to complete personal information of patients is prohibited; When doctors check the screening results of patients, they also need to pass secondary identity verification (such as dynamic verification codes, biometric identification) to ensure the authenticity and credibility of the operating subject's identity. At the same time, establish a detailed operation log recording system to keep track of every data access, modification, deletion, and other operation, recording information such as access time, operator, and operation content. Once there is an abnormal change in data, the root cause of the problem can be quickly identified through backtracking logs, which facilitates accountability and rectification. In addition, strict permission approval processes should be established for external partner organizations or temporary access needs, specifying the access period and data usage scope, and automatically revoking permissions upon expiration to avoid the risk of data leakage caused by permission abuse.

　　建立應急響應機制：提升危機處理的 “快速反應力”

　　Establishing an emergency response mechanism: enhancing the "rapid response capability" of crisis management

　　即便采取了嚴密的防護措施，網絡攻擊和數據泄露風險仍難以完全杜絕，因此完善的應急響應機制不可或缺。兩癌篩查系統需制定詳細的應急預案，明確數據泄露事件發生時的處理流程與責任分工。一旦發現異常，如系統出現不明登錄、數據異常下載等情況，安全團隊需在第一時間切斷可疑網絡連接，防止數據進一步泄露；同時，啟動數據恢復流程，利用預先設置的備份數據（建議采用異地多副本備份策略，定期進行數據完整性驗證），將系統恢復至正常狀態。此外，及時向相關部門和受影響的患者通報事件情況，主動承擔責任并采取補救措施，如為患者提供身份信息保護建議、加強后續數據監控等，最大限度降低事件對患者和系統的負面影響。

　　Even with strict protective measures, the risks of network attacks and data breaches are still difficult to completely eliminate, so a sound emergency response mechanism is indispensable. The two cancer screening systems need to develop detailed emergency plans, clarify the handling procedures and division of responsibilities in the event of a data breach. Once abnormalities are detected, such as unknown login or abnormal data downloads, the security team needs to cut off suspicious network connections as soon as possible to prevent further data leakage; At the same time, initiate the data recovery process and use pre-set backup data (it is recommended to adopt a remote multi copy backup strategy and conduct regular data integrity verification) to restore the system to a normal state. In addition, timely report the incident situation to relevant departments and affected patients, take proactive responsibility and take remedial measures, such as providing identity information protection suggestions for patients, strengthening follow-up data monitoring, etc., to minimize the negative impact of the incident on patients and the system.

　　加強人員管理與培訓：夯實安全意識的 “思想防線”

　　Strengthening personnel management and training: strengthening the "ideological defense line" of safety awareness

　　系統的安全防護最終依賴于人的操作，因此強化人員安全意識與技能培訓至關重要。對參與兩癌篩查系統工作的所有人員，包括醫護人員、技術人員、管理人員等，定期開展網絡安全知識培訓，內容涵蓋密碼設置規范、釣魚郵件識別、社交工程防范等基礎技能，以及數據泄露的法律責任與后果。通過案例分析、模擬演練等形式，讓工作人員直觀認識到網絡安全的重要性，提升其風險防范意識。同時，建立嚴格的人員管理制度，對新入職人員進行背景審查，離職人員及時注銷賬號并收回權限；鼓勵內部監督舉報，對違反安全規定的行為嚴肅處理，形成全員參與、共同維護系統安全的良好氛圍。

　　The security protection of the system ultimately depends on human operation, so strengthening personnel safety awareness and skill training is crucial. Regularly conduct cybersecurity training for all personnel involved in the two cancer screening system, including medical staff, technicians, management personnel, etc., covering basic skills such as password setting standards, phishing email recognition, social engineering prevention, as well as legal responsibilities and consequences for data breaches. Through case analysis, simulation exercises, and other forms, the staff can intuitively recognize the importance of network security and enhance their risk prevention awareness. At the same time, establish a strict personnel management system, conduct background checks on newly hired personnel, and promptly cancel accounts and revoke permissions for departing personnel; Encourage internal supervision and reporting, take serious measures against violations of safety regulations, and create a good atmosphere of full participation and joint maintenance of system security.
