High Way Networking Tolling System Security Project (ETC)
Engineering background
The optical transmission system of the toll system of the Pearl River Delta region of the highway is used SDH digital transmission equipment, and the network structure is the chain structure.. The transmission signal uses the basic module STM-4 signal (rate 622Mbit/s). There is a big difference between different sections, management system and technical force.. Most of the section of the management system is loose, the staff of the network security awareness is weak, there is a big security risk.
Scheme advantages
High reliability
The products used in this program are of MTBF greater than 10000 hours.
High scalability
This scheme chooses the linkage protocol of the firewall, IDS, antivirus wall and the technology network equipment, supports the linkage with other brand equipments, and is beneficial to protect the investment of the owner.. The selected firewall supports VPN, which is convenient for the expansion of owner's network in future..
High defensive
The firewall, IDS, anti-virus wall constitute a three-dimensional protection system, the firewall isolation regional security; IDS real-time detection of network data flow; gas wall can not only cut off the virus spread in the network access can also be controlled host on the network virus preventing and killing, which is general gateway antivirus wall do not have the function.
High performance
The IDS and antivirus walls in the program are connected with the bypass mode, and have no effect on the network performance.. The device itself monitors the network packets through high performance kernels.
