巧设CTC路由器ACL降低网络安全风险

How to Set CTC Router's ACL to Reduce Risks in Network Security

铁路CTC网络均采用了带访问控制功能的路由器,正确地设置ACL(访问控制列表),将起到防火墙的作用,降低网络安全风险。在CTC网络路由器上进行规则设定,可阻挡不匹配安全规则的数据包,确保CTC网络安全。

All the railway CTC networks use routers with access control function, which will play the role of firewalls to reduce network security risks through correctly setting their Access Control Lists. Setting the rules of the CTC network routers can block packets that do not match safety rules to achieve the secur- ity of CTC networks.
