DNS Security.txt

The DNS Security TXT standard provides machine-readable records that define core attributes of your VDP, and is designed to be hosted using DNS TXT records in your domain/s.

Just as security.txt can be deployed into either the root or the .well-known directory of a webserver, DNS Security TXT can be deployed to either the apex of a domain, or under a specially created _security.<domain.com> subdomain. This approach allows organizations to decide the approach that suits them best.
