通過集成到微控制器的技術提高安全性

　　當安全在我們的直接控制之下，這是日常生活中顯而易見的一個方面；我們鎖上門窗，我們不把貴重物品放在普通的視線里，我們在電子支付時保護我們的別針。然而，當安全級別不是我們的直接控制下變得更加模糊；不清楚為什么安全是必要的，事實上，它是如何實現的。

　　越來越多的嵌入式電子設備出現了這種情況，因為它們現在實現了某種程度的連接，但在歷史上對安全問題不敏感。

　　如果存在秘密連接，例如在生產能力聯網的工業設備，或醫療設備，使病人信息的訪問-危險可能不清楚，或往往，甚至在當地存在。由于連通性是全球性的現象，遠程攻擊的危險也是如此，這增加了遠遠超出鄰近地區的安全問題。來自地球另一端的威脅可能是特定的——或者可能是無意的——瞄準良性設備，并將這種威脅擴展到它隨后訪問的任何其他設備。

　　因此，物聯網很可能會促進嵌入式安全的問題，遠遠超出局域網或可見的威脅。

　　What is a security threat？

　　There are many aspects to security in electronic devices today. Predominantly， these can be categorized as threats to either content， intellectual property， or personal data. The trends behind the cost and benefits of adding connectivity are moving positively， but this is only possible thanks to another trend – the use of more diverse hardware solutions and the adoption of open source software.

　　While these are both， ostensibly， also positive， the effect is increased difficulty in guaranteeing security. When networking was first introduced， it was under the control of a small number of providers， which made the need for security almost moot. As connectivity has proliferated， the diversity in hardware and software solutions makes security harder to impose， unless you remain in complete control of your platform （such as Apple）。 Even then， threats can never be entirely mitigated. Security， therefore， is any method by which a threat can be curtailed or controlled. This accepts that threats cannot be entirely avoided but must， instead， have equal and preferably greater countermeasures.
