Overview
DNS firewall is a network security technology based on Domain Name System (DNS) layer protection. By filtering and monitoring DNS traffic in real time, it blocks malicious domain name resolution requests, preventing users or systems from accessing high-risk targets such as phishing websites and malware distribution sites. The software version of DNS firewall supports local deployment, offers lower latency, and effectively protects your internal network security.
Solution architecture
Highly reliable security threat intelligence: The intelligence database of DNS firewall comes from Alibaba Cloud's native threat intelligence database, which is accurate and comprehensive. This effectively ensures the accuracy of threat detection while also providing rich contextual information.
Real-time security threat defense: Real-time interception of threat domain requests, such as phishing websites and Trojans. You can precisely locate compromised hosts and block high-risk DNS queries to prevent external communications.
Block threats from the Internet navigation entry point: Unlike other firewalls that cannot cover domain-layer risks, DNS firewall is based on the DNS protocol with lightweight deployment, capable of blocking threat domain resolution in the early stages of the attack chain.
Fully self-developed software, easy to deploy and manage: The software version of DNS firewall is part of Alibaba Cloud's integrated DNS software. This software is independently developed by Alibaba Cloud, supporting distributed deployment and management with lightweight deployment and simple installation.
Detailed reports and logs to help trace threats: Provides a comprehensive overview of interception and protection status. Through threat intelligence, you can intuitively see the proportion of threat domains, threat type distribution, compromised hosts, and other key information. This helps you understand the DNS security status of your internal network and accurately trace threat sources.
