In the ever-evolving landscape of digital security, certificate authorities (CAs) like DigiCert play a crucial role in ensuring the safety and integrity of online communications. However, even the most reputable entities can encounter issues. On July 29, 2024, DigiCert announced a significant recall of certain digital certificates, notifying clients that they had 24 hours until revocation to replace their issued security certificates. This incident caused many IT teams with global networks to pause other initiative and focus resources on remediation.
Understanding Digital Certificates
What Are Digital Certificates?
Digital certificates are electronic credentials that verify the identity of websites and organizations, enabling secure communication over the internet. They are essential for establishing encrypted connections and ensuring data integrity.
What is a Certificate Authority (CA)?
A certificate authority (CA) is a trusted organization that issues digital certificates. These certificates are used to verify the ownership of a public key by the named subject of the certificate, ensuring secure communication over the internet. When you see a padlock icon in your browser’s address bar, it indicates that the website has a valid certificate issued by a CA, confirming that the site is secure.
CAs play a crucial role in internet security by:
- Validating domain ownership: They confirm that the entity requesting the certificate owns the domain.
- Issuing digital certificates: These certificates enable HTTPS, ensuring encrypted communication between your browser and the website.
- Maintaining trust: CAs adhere to strict industry standards to maintain trust and security across the web.
Some well-known CAs include DigiCert, Let’s Encrypt, and GlobalSign. Without CAs, online transactions and communications would be much less secure.
