DNS.1.13.DDOS
Describe the solutions and mitigations to be used to thwart Distributed Denial of Service (DDOS) attacks against the authoritative DNS services.
Response
We primarily rely on the traffic cleaning services (7x24 on-call manual intervention) and intelligent protection functions (routinely enabled) provided by upstream network service providers. At the same time, we combine our own network technical means (such as Access Control Lists (ACLs), route blackhole policies, Anycast technology, and elastic emergency bandwidth) to comprehensively achieve DDoS attack protection against DNS.
In daily operations, the DNS domain name system infrastructure has achieved real-time monitoring, and all monitoring alert information is integrated into a centralized monitoring system. The monitoring system possesses the capability to identify traffic anomalies, enabling it to capture risk signals such as sudden spikes in abnormal query volumes, unusual access frequencies, and abnormal traffic sources in real time, rather than only triggering alerts when the domain name system service is interrupted. For different attack scenarios, the monitoring system has preset corresponding traffic thresholds. Additionally, a professional 7x24-hour duty team is available to ensure timely response to emergency handling related to distributed denial of service attacks. When the system receives alert information exceeding the preset threshold, the duty personnel will conduct a secondary verification of the traffic anomalies, and then analyze and initiate a matching protection strategy based on the type of attack, traffic scale, and impact scope. For example, external traffic cleaning services are not continuously enabled and require manual intervention from the 7x24-hour duty team to activate. The traffic is redirected through a Border Gateway Protocol (BGP) announcement, directing the target traffic to the cleaning center. After completing the attack protection operation, the 7x24 duty personnel will produce an event handling report. The relevant service operation and maintenance team will comprehensively analyze and process the incident for continuous optimization, and the report will be reviewed and commented by leaders.

DNS.2.10.IaC
Does or will this RSP use Infrastructure-as-Code (IaC) to manage all systems relevant to operation of the registry services under application?
Response
No - Currently, although we have not introduced IaC into the field of operation and maintenance management, we have implemented numerous measures and processes aimed at reducing the potential security and stability risks arising from manual operations in operation and maintenance management.
Firstly, through service process management, we strictly regulate every aspect of the service delivery, service launch, service change, and service decommissioning processes, involving multi-level approval processes. These processes are executed after being approved by the technical supervisor. For major operations involving the overall stability of the system, they must be reported to senior management for final confirmation before implementation, and we ensure that every delivery and change of the service deployment package is traceable and reversible. The service deployment package undergoes unit testing, integration testing, security testing, and other stages in the R&D department to ensure that the code deployment does not affect system stability. After being delivered to the operation and maintenance management department, the operation and maintenance management department verifies the functions of the service deployment after launch through gray release, and can perform rollback operations at any time if there are issues. In addition, for operations involving changes to database metadata or business data, the DBA strictly controls the change statements, performs change and deployment verification in the OT&E environment, and then deploys and upgrades in the production environment.
Secondly, a log audit system is deployed on the execution operation terminal and server to record all manual operations in their entirety and ensure they cannot be tampered with.
And through real-time monitoring, core indicators related to manual operations (such as DNS resolution success rate, system response time, key status, etc.) are monitored in real-time, with multi-level alarm thresholds set. In the event of operational anomalies (such as resolution failure due to configuration errors), the system alarm is immediately triggered to ensure that operation and maintenance personnel respond promptly.
DNS.2.11.Automated Orchestration
Does or will this RSP use automated orchestration to manage all systems relevant to the operation of the registry services under application?
Response
No - We have adopted Ansible for configuration management to enhance work efficiency, reduce the risks associated with manual operations, and ensure consistency, repeatability, and verifiability in executing large-scale operations and maintenance tasks. Some services utilize Docker containerization technology to simplify service deployment and launch processes, but we have not yet employed Kubernetes for container orchestration and management.
DNS.3.3.DNS Resiliency
Describe the methods resiliency for DNS, including the use of anycast, primary and secondary DNS authoritative servers, and hidden DNS zone transfer servers.
Response
The elastic design leveraging IP Anycast technology enables the DNS system to dynamically expand or contract nodes based on real-time network status and traffic demands, automatically optimizing routing and allocating traffic to ensure high availability and fault tolerance. The DNS zone data updating employs a multi-layered primary-secondary update mechanism, wherein the leaf nodes at the outer layer exclusively provide resolution query services, while the hidden DNS zone servers are responsible for data transmission. This architecture bolsters the stability and consistency of DNS resolution services. Refer to Annex 5.
