The design of secure embedded VPN gateway

摘要

As the information transmission in public network has the risk of eavesdropping, and network application terminal is under the attack of viruses or Trojan, it is necessary to do some research on system topology structure, such as to adopt the embedded firewall, IPSec VPN and Network Quarantine based on Iptables rules to get the software and hardware design scheme. The design and implementation of embedded VPN gateway increases the system cost to some extent, but the security of data transmission and application terminal protection capability has been greatly improved, which has good application prospects.
