TRICONEX 4351B 通信模块 并进行验证它们永远无法从互联网上访问

4351B    通信模块

我们强烈推荐以下行业网络安全佳实践，例如:定位防火墙后的控制和安全系统网络和远程设备将它们与业务网络隔离。
安装物理控制，使未经授权的人员无法访问您的工业控制和安全系统、组件、外围设备和网络。
将所有控制器放在上锁的机柜中，不要让它们处于“程序”模式。
扫描与隔离网络的所有移动数据交换方法,如cd, USB驱动器等，在连接到这些网络的终端或节点中使用之前。
●永远不要让之前连接过网络的笔记本电脑连接安全或控制网络连接到那些没有适当卫生设施的网络。
小化所有控制系统设备和系统的网络暴露，并进行验证它们永远无法从互联网上访问。
当需要远程访问时，请使用安全的方式，如虚拟专用网。认识到vpn可能存在漏洞，应该更新到大可用的当前版本。此外，要认识到vpn的安全性
取决于连接设备。
施耐德电气继续建议客户始终执行说明书中的说明所提供的用户文档中的“安全注意事项”部分,其中包括后:
●确保Triconex解决方案中的网络安全功能始终处于启用状态。
始终在隔离的网络上部署安全系统。
●确保所有trstation工程工作站的安全,不要连接任何其他网络比安全的网络。
●配置操作员站显示报警每当Tricon键开关在"程序”模式。

We strongly recommend the following industry network security best practices, such as locating control and security system networks behind firewalls and isolating remote devices from business networks.
Install physical controls to prevent unauthorized personnel from accessing your industrial control and security systems, components, peripherals, and networks.
Place all controllers in a locked cabinet and do not put them in 'program' mode.
Scan and isolate all mobile data exchange methods for networks, such as CDs, USB drives, etc., before using them in terminals or nodes connected to these networks.
Never allow laptops that have previously been connected to the network to connect securely or control network connections to networks without appropriate sanitation facilities.
Minimize the network exposure of all control system devices and systems, and verify that they are never accessible from the internet.
When remote access is required, please use secure methods such as virtual private networks. Realizing that VPN may have vulnerabilities, it should be updated to the maximum available current version. In addition, it is important to recognize the security of VPN
Depends on the connected device.
Schneider Electric continues to recommend that customers always follow the instructions in the user manual provided in the "Safety Precautions" section, which includes the following:
Ensure that the network security features in the Triconex solution are always enabled.
Always deploy security systems on isolated networks.
Ensure the security of all trstation engineering workstations and do not connect to any other network that is more secure than a secure one.
● Configure the operator station to display alarms whenever the Tricon key switch is in "program" mode.
