DNS inherently lacks security,
and the design of DNSSEC was to protect networks from attacks such as
DNS cache poisoning. Domain Name System Security Extensions (DNSSEC) is an essential
specification for securing traditional DNS, providing data integrity,
and origin authentication of DNS data. At TCPWave, we understand the criticality of
securing DNS and offer our customers the option to deploy DNSSEC,
which adds an additional layer of security to their networks. In the
past few decades, DNS has remained unchanged in its implementation
despite its vulnerabilities, posing a severe threat to any
organization that relies heavily on it. DNSSEC was designed as an
improvement over DNS, protecting networks from pervasive threats such
as DNS cache poisoning, DNS redirection, malware, and
man-in-the-middle attacks. DNSSEC provides data integrity and origin
authentication of DNS data through public-key encryption and
validation of data using a digital signature.
