After discussing CAA record in DNS to whitelist your certificate authorities in my previous article, do you know it’s a matter of time that someone finds an issue with your web-presence, website or any front-facing application? If they do, what do you expect them to do? Keep it under the wrap, or disclose it to you “responsibly”? This article is for you if you advocate the responsible disclosure; else, you have to do catch up with reality (I shall come back to you later!

It’s been a long time since I audited someone’s DNS file but recently while checking a client’s DNS configuration I was surprised that the CAA records were set randomly “so to speak”. I discussed with the administrator and was surprised to see that he has no clue of CAA, how it works and why is it so important to enable it correctly. That made me wonder, how many of us actually know that; and how can it be a savior if someone attempts to get SSL certificate for your domain.
