The white paper “DNS Best Practices” by Infoblox presents essential guidelines for securing Domain Name System (DNS) infrastructure. The paper emphasizes that a properly secured DNS is critical to organizations’ digital resilience and offers practical recommendations for minimizing the risks of cyber threats.
DNS is essential for translating domain names into IP addresses. A failure in the DNS infrastructure can lead to significant operational problems. Therefore, organizations should regularly evaluate their DNS servers to ensure they have sufficient capacity and are optimally configured.
The report discusses DNS’s impact on cyber resilience and the principles of Zero Trust. It explains how DNS is often overlooked in security strategies even though it plays an important role in protecting networks from attack. It emphasizes that organizations should use DNS as a fundamental layer in their cybersecurity architecture.
It also identifies several threat vectors to DNS, such as DDoS attacks and unauthorized configuration changes. The paper provides a detailed overview of DNS security best practices, including implementing Protective DNS, protecting the DNS protocol and ensuring the integrity of DNS services.
The report concludes with recommendations for network and security administrators, including using encryption for DNS traffic and deploying dedicated DNS servers to reduce attack vectors.
