The UK National Cyber Security Centre (NCSC) has recently unveiled a set of security guidelines tailored specifically for domain registrars and operators of Domain Name System (DNS) services. These guidelines are designed to empower DNS registrars to play a pivotal role in combating domain abuses at every stage of a domain’s life cycle.

According to the NCSC, DNS registrars hold a crucial responsibility in thwarting domain abuses by preventing the registration of deceptive domains, expediting the removal of malicious domains, assisting clients in securing and maintaining their domain registrations, and mitigating the prevalence of vulnerable systems susceptible to exploitation for malicious activities.

The guidance provided by the NCSC draws inspiration from established industry best practices endorsed by global entities like ICANN. By adhering to these guidelines, domain and DNS registrars can significantly minimize the occurrence of malicious and abusive domain registrations exploited for nefarious purposes such as malware dissemination, spam propagation, phishing site hosting, and botnet operations.

Key recommendations outlined in the guidelines include the implementation of rigorous automated security checks during the registration process, supplemented by manual verifications when necessary. This involves validating the authenticity of contact and payment details to identify any history of fraudulent activities. Additionally, domain registrars are advised to deploy robust security controls during domain registration, proactively monitor new registrations to preemptively detect misleading domains, collaborate with other registrars and infrastructure providers to share pertinent information, and assist clients in configuring domains to enhance security measures.

Furthermore, domain registrars are encouraged to offer advanced security features to prevent unauthorized alterations or transfers of domains, such as supporting multi-factor authentication, utilizing revocable API access tokens, implementing change detection mechanisms, and providing prompt response mechanisms to address abuse reports effectively.

To ensure a coordinated response to abusive behaviors, domain registrars and DNS operators are urged to swiftly address and resolve abuse complaints, actively monitor and address potentially abusive customer activities, share intelligence on identified abusive behaviors with industry peers, and proactively disclose security incidents and compromises to domain holders.

Acknowledging the diversity in operational practices among domain registration organizations, the NCSC emphasizes the need for tailored application of these principles based on individual business models. By embracing these comprehensive security guidelines, domain registrars can fortify their defenses against domain abuses and contribute to a more secure online ecosystem.
