Cluster mail system routing scheme under physical isolation of intranet (4)

NIC soft switch hardware isolation; network layer isolation; application-Layer Security verification

5.2 High Mail exchange efficiency

Ethernet based communications, 10m-100m/s

5.3 Distributed architecture, strong scalability

The Mail routing table can be modified at any time and can be deleted from the quarantine buffer server.

5.4 Completely automatic operation, without manual intervention, reduce human error.

The system timer triggers the mail route forwarding program periodically, without human intervention.

5.5 Data synchronization cycle, frequency can be changed according to the need and the size of the message data at any time.

Provides a more convenient and flexible choice.

5.6 With the mail system monitoring program with the use, can monitor the online mail data flow, at any time to master the system operating conditions.

5.7 Reservation mail Filter program, virus scanner call interface, can achieve system-level spam filtering and virus scanning.

6, note * Above IP address for the assumption of IP, specific implementation needs according to SIIM actual network environment designated IP.
* Minimum mail data interchange interval >= The amount of time required to transfer the volume of mail data in 1 Exchange cycles.

7. Conclusion based on the premise of guaranteeing the absolute security of intranet, the message isolation system of Fortress host can realize the reliable exchange of internal and external network mail system, which is a convenient and easy way. Many of the security scenarios are based on bastion hosts, and there are many success stories that do not carry any technical risk.
