حول هذه الخدمة

Our DNS Server Security Assessment provides comprehensive evaluation of Domain Name System infrastructure to identify vulnerabilities in DNS protocols, configuration weaknesses, and security gaps. We assess DNS servers, recursive resolvers, authoritative servers, and DNSSEC implementations to ensure your DNS infrastructure is secure against cache poisoning, DDoS attacks, DNS hijacking, and other DNS-related threats.

What's Included

DNS protocol vulnerability analysis (cache poisoning, amplification, DDoS)

DNSSEC implementation and configuration review

DNS server configuration hardening assessment

Recursive resolver security evaluation

Zone transfer security testing

DNS query and response security analysis

DNS logging and monitoring review

DNS infrastructure architecture assessment

DNS over HTTPS (DoH) and DNS over TLS (DoT) evaluation

Compliance and best practices review

الأسئلة الشائعة

What DNS server platforms do you assess?

We assess all major DNS server platforms including BIND, PowerDNS, Unbound, Microsoft DNS, and cloud DNS services. Our assessment methodology is platform-agnostic and covers security aspects of each.

How long does a DNS security assessment take?

DNS security assessment typically takes 1-2 weeks depending on the complexity of your DNS infrastructure, number of DNS servers, DNSSEC implementation, and scope of testing required.

What are common DNS security vulnerabilities?

Common vulnerabilities include cache poisoning, DNS amplification attacks, zone transfer vulnerabilities, unpatched DNS software, misconfigured DNSSEC, open recursive resolvers, and lack of DNS monitoring. We identify all these and provide remediation guidance.
