IoT 安全侧重于保护联网设备及其数据，而 OT 安全则保护控制物理工业流程的系统。

IoT 设备安全的任务是确保数据的完整性和保密性，强调强大的身份验证和加密。OT 安全优先考虑监测和控制实际操作的系统的可用性和安全性。

## 什么是 IoT 安全？

![物联网安全层，包括应用层、支持层、网络层、感知层和网络安全管理层。](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/iot-security.png "物联网安全层，包括应用层、支持层、网络层、感知层和网络安全管理层。")

IoT 设备安全包括旨在保护联网设备及其所在网络的措施。这些保障措施至关重要，因为从消费电子产品到工业传感器，各种设备通常都缺乏内置安全功能。IoT 设备会生成和处理大量数据。因此，这些设备可能成为更广泛的网络基础设施中的漏洞点。

IoT 设备连接的特性增加了数据泄露、未经授权访问和拒绝服务攻击等网络威胁的风险。使用强大的安全协议可以降低这些风险。有效的物联网安全包含加密、强大的身份验证机制和实时监控，以确保数据的保密性、完整性和可用性。

适应和应对新出现的威胁是 IoT 安全不可或缺的一个方面。随着 IoT 生态系统的扩大，网络威胁的潜在攻击面也在扩大。IoT 安全侧重于推进和实施既能应对现有挑战，又能适应不断变化的威胁和漏洞的技术。

## 什么是 OT 安全？

![从 0 级（总线网络）到 5 级（互联网 DMZ）的 OT 安全架构分层图。](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/iot-security-architecture.png "从 0 级（总线网络）到 5 级（互联网 DMZ）的 OT 安全架构分层图。")

OT 安全涉及保护操作技术 (OT) 系统，包括监控 Control and Data Acquisition (SCADA) 系统和工业控制系统 (ICS)，这些系统在制造、公用事业和运输等行业至关重要。这些系统可控制和监控工业流程的运行。随着连接性的提高，确保 OT 资产系统的安全性和完整性变得至关重要。要防范一系列网络威胁和漏洞，就必须制定强有力的安全协议。

实施 OT 安全可应对工业环境固有的具体挑战。与 IT 系统不同，OT 系统优先考虑运行效率和安全性。OT 安全侧重于保护监测和控制运行的物理系统，确保它们能够抵御未经授权的访问和网络威胁，同时保持运行的持续性。

未来的 OT 安全将受到持续适应动态威胁环境的影响，重点是最大限度地降低风险，同时最大限度地提高运行效率。预计策略将包括实时监控操作流程、实施多层次安全协议以及确保合规性符合行业标准和法规。随着 IT 和 OT 之间的融合持续加深，OT 安全工具和战术应力求具有弹性、适应性和全面性，以保护其所支持的关键基础设施和运营。

## 物联网在 OT 中的作用

物联网（IoT）和运营技术（OT）的交叉代表着工业格局的重大转变。IoT 为传统的 OT 系统引入了网络功能，将其转变为能够收集、传输和分析数据的智能单元。与传统的 OT 设备不同，IoT 设备增强了数据的移动性和可访问性，提供实时见解，可用于提高运营效率和决策水平。

在工业运营方面，物联网对 OT 的渗透体现在传感器和其他数据收集单元功能的增强上。智能传感器配备先进的数据处理和通信功能，可在网络上无缝收集和转发运行数据。这种互联性有助于形成一个综合生态系统，让数据从业务前线畅通无阻地流向分析和决策平台。无缝数据传输有助于预测性维护、实时监控和其他有助于优化性能和减少停机时间的操作改进。

IoT 和 OT 的融合有助于边缘计算在工业环境中的传播。IoT 设备配备边缘计算功能，可现场分析和处理数据，无需将数据传输到集中处理中心。这不仅能减少延迟，还能确保实时数据得到及时利用，以便立即进行业务调整

## OT 和 IoT 安全有哪些区别？

![两个色块中的 IoT 安全和 OT 安全功能比较列表。](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/iot-security-vs-ot-security.png "两个色块中的 IoT 安全和 OT 安全功能比较列表。")

操作技术（OT）和物联网（IoT）安全虽然相互交织，但具有不同的特点和挑战。OT 安全为工业和关键基础设施提供保障。其重点是用于监控物理设备和流程的专用硬件和软件。最重要的问题是保持系统的可用性和安全性。在系统中断或故障可能导致灾难性后果的 OT 环境中，OT 安全尤为重要。

而 IoT 安全则集中在大量收集、传输和分析数据的联网设备上。这些设备通常面向消费者，它们联网并支持互联网，扩大了潜在网络威胁的攻击面。物联网安全涉及保障数据的完整性和保密性。OT 主要关注的是系统的可用性，而 IoT 安全则要解决无数设备的问题，每个设备都有独特的漏洞，这就增加了确保设备免受网络威胁的复杂性。

在补救和防御策略方面，OT 和 IoT 也表现出不同之处。OT 系统通常比较老旧，而且嵌入在关键基础设施中，更新或打补丁可能很困难，因此异常检测和 OT 网络分段至关重要。相反，IoT 设备在更新方面具有更大的灵活性，但在设计上往往安全性较低。因此，更改默认凭据和定期软件更新是物联网安全的常见做法。尽管 OT 和 IoT 截然不同，但它们的融合是不可避免的，这就强调了需要采用全面的安全方法，将这两个领域的复杂性囊括在内。

## IoT 与 OT 安全常见问题解答

### 什么是 IoT 和 OT 安全？

IoT 安全涉及保护连接互联网的设备和网络免受网络威胁，重点是数据的完整性和隐私。OT 安全涉及保护管理和控制工业运行的系统，优先考虑其安全和不间断运行。IoT 设备的安全涉及通过互联网传输数据的各种设备，而 OT 安全则侧重于特定的工业控制系统及其可靠性。

### IT 设备、IoT 设备和 OT 设备之间有什么区别？

IT 设备是为数据存储、处理和通信而设计的，如计算机和服务器。OT 设备可控制和监控制造业等行业的物理过程和设备。IoT 设备内嵌传感器和连接功能，可实时收集和交换数据。

### IoT 安全与 OT 安全有什么区别？

IoT 安全涉及对通过互联网进行通信的互联设备的保护，重点是数据隐私和设备完整性。另一方面，OT 安全侧重于确保工业环境中管理和控制物理过程的系统的安全性和可靠性。

### IT 安全与 OT 安全有什么区别？

信息技术安全的重点是保护数据的机密性、完整性和可用性。相比之下，OT 安全则优先考虑工业控制系统和流程的安全性和可靠性，确保持续运行，保护人类和环境安全。

### OT 安全与工业物联网安全有什么区别？

OT 安全侧重于保护监测和控制物理设备的系统免受网络威胁，确保安全性和可靠性。相比之下，IIoT（工业物联网）安全不仅涵盖互联工业设备的安全性和可靠性，还能抵御互联网连接和数据共享带来的风险。主要区别在于 IIoT 中的互联网连接带来了更广泛的威胁环境和复杂的安全要求。

### OT 安全的未来是什么？

OT 安全的未来并不确定。与所有技术和安全领域一样，随着行业需求和威胁形势的变化，OT 安全也在不断发展。为了解决因与 IT 和 IoT 系统深度集成而增加的复杂性和脆弱性，OT 安全很可能会不断发展。适应新兴技术和威胁将至关重要。

### 什么是 OT 安全技术？

OT 安全技术包括各种工具和系统，旨在保护工业和运行环境的完整性、可用性和安全性。其重点是保护物理过程和机械免受网络威胁和干扰。这些技术是根据操作技术的具体需要和要求量身定制的，有别于传统的 IT 安全解决方案。
