51154724-100 MODBUS/TCP防火墻

51154724-100是一款Modbus/TCP防火墻，用于保護(hù)Modbus/TCP通信安全的網(wǎng)絡(luò)設(shè)備。Modbus是一種串行通信協(xié)議，廣泛應(yīng)用于工業(yè)控制系統(tǒng)，而TCP（傳輸控制協(xié)議）則是互聯(lián)網(wǎng)協(xié)議族（TCP/IP協(xié)議族）中的一種面向連接的、可靠的、基于字節(jié)流的傳輸層通信協(xié)議。Modbus/TCP則是將Modbus協(xié)議與TCP/IP協(xié)議相結(jié)合，實(shí)現(xiàn)了在工業(yè)以太網(wǎng)中的廣泛應(yīng)用。

51154724-100的主要功能是監(jiān)控和控制進(jìn)出網(wǎng)絡(luò)的流量，以保護(hù)網(wǎng)絡(luò)免受未經(jīng)授權(quán)的訪問和攻擊。對(duì)于Modbus/TCP防火墻來說，它特別針對(duì)Modbus/TCP通信進(jìn)行深度包檢測(cè)、過濾和控制，確保只有合法的、符合安全策略的數(shù)據(jù)包能夠通過。

51154724-100可以實(shí)現(xiàn)以下功能：

1. 訪問控制：通過包過濾機(jī)制，按照網(wǎng)絡(luò)管理員制定的訪問規(guī)則，對(duì)Modbus/TCP數(shù)據(jù)包進(jìn)行過濾，攔截不符合規(guī)則的數(shù)據(jù)包，防止未經(jīng)授權(quán)的訪問。
2. 防御常見攻擊：掃描通過Modbus/TCP上傳與下載的文件，發(fā)現(xiàn)其中包含的危險(xiǎn)信息，并通過控制、檢測(cè)與報(bào)警機(jī)制，在一定程度上防止或減輕針對(duì)Modbus/TCP的攻擊。
3. 深度包解析：針對(duì)Modbus/TCP協(xié)議進(jìn)行深度解析，理解數(shù)據(jù)包的內(nèi)容和結(jié)構(gòu)，從而更精確地判斷數(shù)據(jù)包的合法性。
4. 白名單機(jī)制：基于Modbus/TCP白名單，對(duì)合法的設(shè)備和通信進(jìn)行智能保護(hù)，只允許白名單中的設(shè)備和通信通過防火墻。
5. 記錄和審計(jì)：作為審計(jì)和記錄Internet使用費(fèi)用的一個(gè)最佳地點(diǎn)，網(wǎng)絡(luò)管理員可以依此向管理部門提供Internet連接的費(fèi)用情況，查出潛在的帶寬瓶頸位置，并能夠依據(jù)本機(jī)構(gòu)的核算模式提供部門級(jí)的計(jì)費(fèi)。

請(qǐng)注意，Modbus/TCP防火墻的配置和管理需要由專業(yè)的網(wǎng)絡(luò)安全人員來進(jìn)行，以確保其能夠有效地保護(hù)網(wǎng)絡(luò)的安全。同時(shí)，也需要定期更新防火墻的規(guī)則和策略，以應(yīng)對(duì)不斷變化的網(wǎng)絡(luò)安全威脅。

51154724-100 MODBUS/TCP防火墻

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.
