Abstract

O estudo do protocolo DNS (Domain Name System) faz se necessário devido a sua grande importância para a estabilidade e confiança da internet que hoje conhecemos. O protocolo DNS nativo traz algumas vulnerabilidades intrínsecas em seu protocolo, tais como envenenamento de cache e impersonificação de servidores DNS. Hoje, temos uma extensão segura do protocolo DNS, denominado DNSSEC (Domain Name System Security Extensions), capaz de prover autenticidade nas requisições de DNS, garantindo assim a integridade dos pacotes DNS. Além desta extensão segura, existe outra denominada DNSCurve bem mais robusta porém consome mais recursos, devido todos os pacotes DNS utilizarem criptografia, desde sua origem até o destino.
