DNS over HTTPS (DoH) is rapidly gaining traction as a more secure and private alternative to traditional DNS queries. This guide explores how Infoblox, a leading provider of network control solutions, integrates with and supports DoH, addressing key considerations for network administrators.
Traditional DNS queries are sent in plain text over UDP or TCP, making them vulnerable to eavesdropping and manipulation. DoH encrypts these queries using HTTPS, the same protocol used for secure web browsing. This provides several key benefits:
Infoblox offers several ways to integrate with and manage DoH within your network infrastructure. While Infoblox doesn't directly offer a DoH *recursive* resolver as a standalone product in the same way as some public DoH providers (like Cloudflare or Google), its solutions play a crucial role in managing and securing DoH deployments within an organization's network.
Infoblox's DNS solutions can be configured to forward DNS queries to external DoH resolvers. This allows you to leverage the security and privacy benefits of DoH while still maintaining control over your DNS infrastructure. This is often the preferred method for organizations looking to utilize public DoH resolvers.
Infoblox's security features, such as DNSSEC validation and advanced threat intelligence, can be employed to further enhance the security of your DoH implementation. Even when forwarding queries to an external DoH provider, Infoblox can filter and block malicious responses before they reach end-users, adding an extra layer of protection.
Infoblox BloxOne Threat Defense provides comprehensive threat protection, including DNS security features, that are particularly relevant when using DoH. Its features help mitigate against malicious websites regardless of whether your DNS requests are using DoH or traditional DNS. It offers advanced threat intelligence and can filter out malicious responses, even if they've been returned via a seemingly legitimate DoH resolver.
Infoblox provides a centralized platform for managing DNS policies and security configurations. This allows administrators to easily monitor and control DoH usage across their network, ensuring consistent security and performance.
Infoblox plays a significant role in enabling secure and managed DoH deployments. By integrating its solutions with external DoH resolvers or by leveraging its security features, organizations can enjoy the privacy and security benefits of DoH while retaining central control and visibility over their DNS infrastructure. Careful planning, configuration, and ongoing monitoring are crucial for a successful DoH implementation with Infoblox.
