Certbot and Let's Encrypt Now Support IP Address Certificates
Summary
Certbot, the client for Let's Encrypt, has been updated to support obtaining IP address certificates. This new functionality allows users to secure services running on IP addresses rather than domain names, with a current limitation of only supporting certificate issuance and not automatic installation on web servers.
IFF Assessment
This development is good for defenders as it expands the ability to secure network services using trusted certificates, thereby improving the security posture of systems identified by IP addresses.
Defender Context
The ability to obtain IP address certificates is a useful advancement for securing services that may not have traditional domain names. Defenders should be aware of this capability and ensure that any systems using IP-based certificates are properly managed and secured, as they represent a new vector for certificate-based security.
