DNS security can be improved with cookies, suggest IETF boffins
A proposal raised late May at the Internet Engineering Task Force (IETF) suggests adding cookies to the DNS to help defend the critical system against denial-of-service exploits.
The domain name system (DNS) is an old and fundamental piece of the Internet architecture, providing translation between human-readable addresses like theregister.co.uk and IP addresses.
The DNS has also been exploited several times over the years as a traffic amplifier in DoS attacks. [amplification attacks] RFC 7873, authored by Donald Eastlake (Huawei*) and Mark Andrews (ISC*), puts forward the intriguing notion that a simple cookie deployment could help.
