Google and a few other companies provide open dns resolvers to the people around the globe. Unfortunately it may happen that the resolver was hijacked and used for different purposes, such as redirecting to malicious pages or to block certain addresses (censorship).
Our goal is to identify hijacked resolvers by analyzing their fingerprints, in order to increase safety of Internet users. To do that, we utilize data collected via RIPE Atlas (atlas.ripe.net).
Create and validate TLSA records (DANE)
Hi,
I've talked about SSHFP in my last blog post and now, let’s talk about TLSA, another useful DNS record to put in a DNSSEC secured zone.
I will apply the example to HTTPS here but you can do this for everything that use TLS in fact (except for the web browser plugin part).
