Study Notes
資訊安全
在本文中，我們將探討以下主要的子題：資訊安全原則、加密技術、資料保護、網路安全和惡意軟件防護。這些領域都是在現代數位時代重要且有益的知識。
資訊安全原則
資訊安全原則是一種遵循業界監管標準的系統化方法，用於為組織定義其對於資料庫及機器等硬體設備與軟體使用者之間的安全性需求。這些原則包括建立、執行和控制內部政策Required、建立、執行和控制內部流程Controls、和執行與控制基准 Standards。
加密技術
加密技術是一種將資訊轉換成不可解釋形式的方法，以確保專門人士只能取得資訊的安全存取。這些技術通常被分類為單向加密（一個方向上）或雙向加密（兩個方向上）。例如，SSL、TLS、S/MIME、PGP、DKIM、DMARC 和 SPF 都是著名的加密技術。
資料保護
資料保護是指在電腦和通過網際網路傳送的任何數據中，保持數據的完整性、可用性、私密性和語言。數據保護的顯著好處包括提高客戶信心并促進創新。在資訊安全領域中，資料保護通常會與加密技術相互動作，以確保數據的安全存取。
網路安全
網路安全是指使用者和計算機系統通過網路進行交易、存取資源和共享資訊而不受攻擊者威脅的情況。網路安全的最佳實務包括如何避免網站感染病毒、應該從哪裡獲取安全軟體、如何阻止駭客入侵、如何停止駭客破壞您的網站並請求金額，以及如何避免端點感染病毒。
惡意軟件防護
惡意軟件防護是指利用人工智能或風险形象來預測和防止電腦以外的非公開漏洞的方法。這些方法通常通過大量數據集合的自動學習來生成獨特的模型，並在行動端裝置上进行綜合運算。
在這五個領域中，我們可以看到資訊安全是一個複雜且多面的問題，它不但涉及到技術和手段的研究發展，更重要的是，它也涉及到規範和法律的制定，以及社會的認同度。良好的資訊安全實施可能會降低侵略者的可能性，通過責任的行為達成更強大和健康的個人、公司和國家。
