Certificate Authorities (CAs) is a powerful entity whose job is to make sure that every single SSL certificate is authorized by using different methods of domain validation. It is normally done by linking the particular SSL certificate with a particular website using a particular domain. But the CA should be listed as an authorized issuer of the certificate. As CAA specify which CAs are genuine and are allowed to issue a certificate for a domain, it helps in preventing or minimizing chances of hacking or misusing SSL certificate.
How to create CAA record
In order to create a CAA record, DNS (Domain Name System) provider has to be contacted. List of CAs that you prefer should be provided so that unauthorized CAs can not issue SSL Certificates to your domain. If you did not provide with your preferred list of CAs, it automatically gives the right to every single CA to issue an SSL certificate to your domain, which can result in misuse of your domain by any other party.
Benefits of CAA
As benefits of Certificate Authority Authorization (CAA) are clear, the next thing that hits our minds is “Do I need CAA?”. The answer is very clear…YES, we very much need CAA. As we know CAA records are used to check the authenticity of CAs i.e. which CA is authorized to issue SSL certificate as well as it provides an immense amount of security from hackers. It also gives rights to the domain owner to exclude a particular CA. CA can’t issue any Comodo SSL certificate without authentication. In other words, we can say that CAA can bring down the risk of issuing the SSL certificates by unauthorized Certificate Authorities (CAs).
For any domain, CA can issue a certificate and with an increase in HTTPS, there is an increase in SSL certificates. To put control over this, a powerful approach was required. An approach that could not only decrease the risk but put a stop on miss-issuance of SSL certificates. CAA is designed to stop unauthorized issuance of SSL certificates.

Benefits of CAA
- It helps in preventing illegal or unauthorized issuance of Comodo SSL certificate.
- An organization is also helped by limiting CAs they use.
- The site owners are also benefited as they can now specify which Certificate Authorities (CAs) have the authority to issue an SSL certificate to their domain name.
- All the CAs have to check for the authenticity before issuing SSL certificate.
