2. Main Functions
The core function of the ZoTrus SM2 HTTPS Auto 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 Gateway before the original server, then it can automatically implement https encryption, and provide https encryption services 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. A 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.
The dual-algorithm dual-SSL certificate required for HTTPS encryption is automatically completed by the HTTPS Auto Gateway connected to the ZoTrus Cloud SSL System to apply for the dual-SSL certificate, validate the domain name, retrieve the issued SSL certificate, install the SSL certificate, and enable the SSL certificate. The automatically configured ECC SSL certificate is globally trusted and supports the certificate transparency, it is issued by ZoTrus brand intermediate root certificate - ZoTrus ECC DV SSL CA, its root CA certificate is the world oldest ECC algorithm root CA certificate - Sectigo ECC, and the entire chain uses ECC Algorithm, the encryption speed is 18 times faster than the RSA algorithm SSL certificate, to fast access the website by end users. The automatically configured SM2 SSL certificate is compliant with the Cryptography Law and trusted by ZT Browser. It is currently the only SM2 SSL certificate in the world that supports the SM2 Certificate Transparency. It is issued by ZoTrus brand intermediate root certificate - ZoTrus SM2 DV SSL CA, its root CA certificate is ZoTrus SM2 SSL Root, the root CA certificate of ZoTrus brand using SM2 algorithm, which is currently the only SM2 root CA certificate dedicated to issue SM2 SSL certificates, it is trusted by ZT Browser and ZoTrus SM2 Certificate Transparent Log System, the entire chain uses the SM2 algorithm, the encryption speed is 20 times faster than the RSA algorithm, to fast access the website by end users. The certificate chain file of the automatically configured dual SSL certificate is the smallest, saving IDC traffic and user mobile phone traffic, saving IDC power consumption and user mobile phone power consumption, and is more environmentally friendly.
If customer has not purchased WAF device, it is recommended to purchase the WAF module, which is developed based on the open source ModSecurity system, which supports commonly used Web Application Firewall functions, such as: preventing SQL injection, preventing cross-site scripting attacks (XSS), preventing attacks using local files containing vulnerabilities, and preventing the use of remote File (including vulnerabilities) attacks, preventing attacks using remote command execution vulnerabilities, preventing PHP code injection, preventing malicious access that violates the HTTP protocol, preventing attacks using remote proxy infection vulnerabilities, preventing attacks using Shellshock vulnerabilities, and preventing the use of Session sessions Vulnerabilities with the same ID can be used to attack, prevent malicious scanning of websites, prevent source code or error information leakage, blacklist honeypot projects, and perform IP blocking based on judging the IP address attribution, etc.
If customer has already purchased a WAF device, it is only necessary to deploy a SM2 HTTPS Auto Gateway before the WAF device. The WAF device only needs to be responsible for parsing the cleartext http content to make corresponding protection, and there is no need to apply for SSL certificate from the CA to be deployed on the WAF device.

4. Deployment Solutions
ZoTrus SM2 HTTPS Auto 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 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 services.
(1)Gateway routing mode deployment
The two network cards of the ZoTrus SM2 HTTPS Auto Gateway are respectively responsible for processing the internal and external network interfaces of two different routes, and the HTTPS Auto Gateway itself acts as a router or NAT device. All network data traffic is accelerated, offloaded, and converted through the HTTPS Auto 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.
The routing mode deployment requires that the HTTPS Auto 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 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 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 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 Gateway can realize a transparent high-speed encrypted channel to ensure the security of data transmission.
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 Gateways must be deployed to form a cluster array-HTTPS offloading system. Multiple HTTPS Auto 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.
For the deployment of small and medium-sized websites, it is recommended to deploy at least two HTTPS Auto 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:
-
Master-Master mode
Master-Master mode is Active-Active mode: Two HTTPS Auto Gateways are deployed in the network, and both devices act as hosts and process business traffic at the same time, and also serve as backups for each other. When one of the HTTPS Auto Gateways has a problem and cannot continue to work, the other HTTPS Auto Gateway undertakes all the services, so as to ensure that the service scheduling can still be responded to and processed, and there will be no partial interruption in the network. This mode is suitable for the deployment requirements of a redundant network environment (such as VRRP) that emphasizes high availability. This mode is recommended, and the two machines share business traffic without wasting resources. -
Master-Slave mode
The Master-Slave mode is Active-Backup mode: Two HTTPS Auto Gateways are deployed in the network, one handles business traffic and is called the Master; the other is on standby and is called the Backup. While the master is processing business, it will synchronize the session information generated by the business to the backup machine, so as to ensure that after the switchover, the newly initiated business access can continue to be responded to and processed, and the current business access will not be interrupted. This mode is suitable for the deployment requirements of avoiding single point of failure in most network environments. The standby machine in this mode is idle and is not recommended.
(4) Local deployment of Cloud SSL System
By default, the HTTPS Auto Gateway automatically connects with the ZoTrus Cloud SSL System to enable https encryption 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.
