What is DNS Security?
DNS Security is the generic concept of securing the DNS service, this includes securing the service, the protocol itself, and other precautions and measures discussed in these pages.
All the basics apply here: keeping the operating system secure, keeping the software up-to-date, having redundant systems in place to ensure service availability, maintaining secure update measures to ensure only authorized personnel can modify DNS entries, etc. This basic (and sometimes boring) layer is often overlooked when considering “DNS security,” but disastrous consequences can ensue when not properly maintained.
