In security ratings, a "DNS Health" rating refers to assessing or evaluating the overall health and integrity of an organization's Domain Name System (DNS) infrastructure. It focuses on the proper functioning and configuration of DNS components, ensuring the reliability and security of DNS services.

The DNS Health rating considers various factors related to DNS infrastructure, including the accuracy and consistency of DNS records, the availability and responsiveness of DNS servers, proper configuration of DNS resolvers, adherence to DNS best practices and standards, and the absence of DNS-related vulnerabilities or misconfigurations.

The DNS Health rating is an essential component of security ratings as DNS plays a critical role in translating domain names into IP addresses and facilitating various internet services. A healthy DNS infrastructure is vital for proper functioning and security.

By evaluating the DNS Health rating, organizations can gain insights into the robustness and reliability of their DNS infrastructure, identify potential vulnerabilities or misconfigurations, and make informed decisions to enhance the health and security of their DNS services.

ThreatNG Security Ratings integrates intelligence substantiated with external attack surface management and digital risk protection capabilities and provides complete coverage of DNS Health through its Cyber Risk Exposure, BEC and Phishing, Brand Damage, and Subdomain Takeover Susceptibility scores with enhanced fidelity and validity in several ways:

Domain Intelligence: By leveraging domain intelligence, the solution can gather comprehensive information about a domain, including historical data, ownership details, and associated infrastructure. This enables a more accurate assessment of the domain's reputation and potential vulnerabilities.

Dark Web Presence: The solution can monitor the dark web for any mentions or activities related to the domain in question. This helps identify if the domain has been compromised or if there are any malicious activities associated with it. By considering dark web presence, the DNS Health rating can reflect the potential risks posed by the domain's involvement in illicit activities.

Sentiment & Financials Discovery: Analyzing sentiment and financial data related to the domain can provide valuable insights into its overall reputation and trustworthiness. By assessing factors such as customer sentiment, financial stability, and business practices, the solution can gauge the domain's reliability and the likelihood of it being involved in malicious activities or scams.

Deeper Inspection for Vulnerabilities: The solution can perform deeper inspections to identify specific vulnerabilities that may impact DNS health. This includes assessing susceptibility to Web Application Hijacking, Subdomain Takeover, Business Email Compromise (BEC), Phishing attacks, and overall Cyber Risk Exposure. Considering these factors, the solution can provide a more comprehensive and accurate DNS Health rating.

By incorporating these intelligence sources and capabilities, the ThreatNG Security Ratings solution can provide a more holistic view of the domain's security posture and potential risks. This, in turn, enhances the fidelity and validity of the DNS Health rating by considering various relevant factors that impact the domain's security and trustworthiness.
