2. Main Functions

The core function of the ZoTrus SM2 HTTPS Auto WAF Gateway is zero reconstruction of the original server, no need to install an SSL certificate on the server, no need to install ACME Client software on the server, and no need to upgrade the server software to support the SM2 algorithm, just deploy HTTPS Auto WAF Gateway before the original server, then it can automatically implement https encryption and WAF protection, and provide https encryption services and WAF protection 24 x 365 days. It is recommended that the default dual-machine deployment be used as hot standby for each other. When it is available, the two gateway work at load balance mode, and when it is not available, one gateway can take over all work. It intercepts attack traffic in real time and only allow legal traffic to pass normally, the free SM2 browser that supports the SM2 algorithm and SM2 Certificate Transparency – ZT Browser uses the SM2 algorithm to realize the SM2 https encryption preferentially, and other browsers that do not support the SM2 algorithm and SM2 Certificate Transparency use ECC algorithm to implement https encryption.

4. Deployment Solutions

ZoTrus SM2 HTTPS Auto WAF Gateway supports multiple network deployment methods, supports cluster deployment of multiple devices, supports automatic docking with ZoTrus Cloud SSL System to automatically configure dual SSL certificates required for https encryption for the Gateway, and also supports localized deployment of ZoTrus Cloud SSL System for e-government cloud or public cloud, which automatically issues dual SSL certificates for local cloud users, and the local HTTPS Auto WAF Gateway device automatically connects to the locally deployed Cloud SSL System. In order to ensure the high availability of the Gateway, dual-machine deployment is strongly recommended to ensure 24*365 uninterrupted provision of https encryption service and WAF protection.

(1)Gateway routing mode deployment

The two network cards of the ZoTrus SM2 HTTPS Auto WAF Gateway are respectively responsible for processing the internal and external network interfaces of two different routes, and the HTTPS Auto WAF Gateway itself acts as a router or NAT device. All network data traffic is accelerated, offloaded, and converted through the HTTPS Auto WAF Gateway. Data packets conforming to the security application protocol will be forwarded to the corresponding internal server according to the load balancing strategy. Other NAT data will not be affected, and standard routing network communication is supported.

Gateway routing mode deployment

The routing mode deployment requires that the HTTPS Auto WAF Gateway and the internal server be deployed on different network segments. It is necessary to assign a public IP address and an intranet IP address to the HTTPS Auto WAF Gateway. And set the Gateway as an intranet gateway and enable the DHCP service, and the internal server is connected to the intranet switch. In this mode, the HTTPS Auto WAF Gateway provides HTTPS encryption, offloading, forwarding and routing service at the same time.

The routing mode deployment will change the IP address of the original server and reassign the intranet IP address to the original server. The original public network IP address is configured for the Gateway, supports IP V4 and IP V6, and the original domain name resolution does not need to be changed.

(2)Gateway to gateway deployment

The ZoTrus SM2 HTTPS Auto WAF Gateway supports separate deployment on the client network and the server network to form a symmetrical "gateway to gateway" topology. The gateway-to-gateway deployment method is very suitable for business exchanges between the central office and the branch office. It can automatically encrypt a large number of application data requests of the branch office, transmit them to the central office through the Internet, and then automatically decrypt the data and send it to the business server. The entire application and the system itself do not need to deal with the https encryption of the communication link. The symmetrically deployed HTTPS Auto WAF Gateway can realize a transparent high-speed encrypted channel to ensure the security of data transmission.

Gateway to gateway deployment

The gateway-to-gateway deployment mode is extremely simple, without changing the original network topology, which greatly reduces the complexity of gateway deployment, and can be widely used in the "bank-enterprise direct connection" business in the financial industry, the ETC networking business in the transportation industry and application scenarios such as business data centralization of systems for enterprise groups and branches.

(3)Gateway cluster deployment

For https encryption applications on the high-traffic websites, e-government cloud platforms and public cloud platforms, multiple HTTPS Auto WAF Gateways must be deployed to form a cluster array-HTTPS offloading system. Multiple HTTPS Auto WAF Gateways work together to share business traffic and serve as hot backup for each other equipment. When one gateway fails, the services running on it can be taken over by other gateways to ensure that business scheduling can be fully and timely responded. The cluster mode is suitable for the deployment requirements of a redundant network environment that emphasizes extremely high-performance throughput.

Gateway cluster deployment

For the deployment of small and medium-sized websites, it is recommended to deploy at least two HTTPS Auto WAF Gateways to realize dual-machine hot backup and ensure uninterrupted 24 hours x 365 days of https encryption services. Two dual-system hot standby modes are optional:

(4) Local deployment of Cloud SSL System

By default, the HTTPS Auto WAF Gateway automatically connects with the ZoTrus Cloud SSL System to enable https encryption and WAF protection after obtaining the dual SSL certificates. For cloud platform customers who want to independently issue their own brand of dual SSL certificates that are automatically deployed to the Gateway, they can deploy the ZoTrus Cloud SSL System locally to realize automatic issuance of the dual SSL certificates by the custom-branded dedicated SSL intermediate root certificate. The locally deployed system is called the E-government Cloud SSL System or the Public Cloud SSL System.

The E-government Cloud SSL System is a locally deployed CA system for issuing cryptography-compliant SSL certificates that support SM2 Certificate Transparency. The deployment of the whole system is to realize the completely independent and controllable issuance and management of SM2 SSL certificates for e-government website and the relatively independent issuance of ECC SSL certificates. To achieve independent and controllable issuance of e-government SSL certificates, first of all, there must be an intermediate root certificate for issuing SSL certificates, so that all e-government systems can reliably realize that all e-government systems only trust SSL certificates issued by their own intermediate root certificates, effectively preventing various SSL man-in-the-middle attacks against e-government websites and other fake e-government website attacks.
