描述

51154724-100 MODBUS/TCP防火墙

51154724-100是一款Modbus/TCP防火墙，用于保护Modbus/TCP通信安全的网络设备。Modbus是一种串行通信协议，广泛应用于工业控制系统，而TCP（传输控制协议）则是互联网协议族（TCP/IP协议族）中的一种面向连接的、可靠的、基于字节流的传输层通信协议。Modbus/TCP则是将Modbus协议与TCP/IP协议相结合，实现了在工业以太网中的广泛应用。

51154724-100的主要功能是监控和控制进出网络的流量，以保护网络免受未经授权的访问和攻击。对于Modbus/TCP防火墙来说，它特别针对Modbus/TCP通信进行深度包检测、过滤和控制，确保只有合法的、符合安全策略的数据包能够通过。

51154724-100可以实现以下功能：

1. 访问控制：通过包过滤机制，按照网络管理员制定的访问规则，对Modbus/TCP数据包进行过滤，拦截不符合规则的数据包，防止未经授权的访问。
2. 防御常见攻击：扫描通过Modbus/TCP上传与下载的文件，发现其中包含的危险信息，并通过控制、检测与报警机制，在一定程度上防止或减轻针对Modbus/TCP的攻击。
3. 深度包解析：针对Modbus/TCP协议进行深度解析，理解数据包的内容和结构，从而更精确地判断数据包的合法性。
4. 白名单机制：基于Modbus/TCP白名单，对合法的设备和通信进行智能保护，只允许白名单中的设备和通信通过防火墙。
5. 记录和审计：作为审计和记录Internet使用费用的一个最佳地点，网络管理员可以依此向管理部门提供Internet连接的费用情况，查出潜在的带宽瓶颈位置，并能够依据本机构的核算模式提供部门级的计费。

请注意，Modbus/TCP防火墙的配置和管理需要由专业的网络安全人员来进行，以确保其能够有效地保护网络的安全。同时，也需要定期更新防火墙的规则和策略，以应对不断变化的网络安全威胁。

51154724-100 MODBUS/TCP防火墙

51154724-100 is a Modbus/TCP firewall used to protect the security of Modbus/TCP communication network devices. Modbus is a serial communication protocol, which is widely used in industrial control systems, while TCP (Transmission Control Protocol) is a connection-oriented, reliable, and byte stream based transport layer communication protocol in the Internet protocol family (TCP/IP protocol family). Modbus/TCP is a combination of Modbus protocol and TCP/IP protocol to achieve a wide range of applications in industrial Ethernet.

The primary function of the 51154724-100 is to monitor and control traffic to and from the network to protect the network from unauthorized access and attacks. For Modbus/TCP firewall, it performs deep packet detection, filtering and control for Modbus/TCP communication to ensure that only legitimate packets that comply with security policies can pass through.

51154724-100 can achieve the following functions:

Access control: Uses the packet filtering mechanism to filter Modbus/TCP packets according to the access rules set by the network administrator, intercepts the packets that do not comply with the rules, and prevents unauthorized access.

Defense against common attacks: Scans files uploaded and downloaded by Modbus/TCP to discover dangerous information, and uses the control, detection, and alarm mechanism to prevent or mitigate attacks against Modbus/TCP to a certain extent.

Deep packet parsing: Performs deep parsing based on Modbus/TCP protocols to understand the content and structure of packets and determine the validity of packets more accurately.

Whitelist mechanism: Based on the Modbus/TCP whitelist, intelligent protection is implemented for legitimate devices and communications. Only the devices and communications in the whitelist are allowed to pass through the firewall.

Recording and auditing: As one of the best places to audit and document Internet usage expenses, network administrators can provide management with the cost of Internet connections, identify potential bandwidth bottlenecks, and provide department-level billing based on their organization’s accounting model.

Please note that the configuration and management of the Modbus/TCP firewall needs to be carried out by professional network security personnel to ensure that it can effectively protect the security of the network. At the same time, it is also necessary to regularly update the rules and policies of the firewall to cope with constantly changing network security threats.
