What is Certificate Authority (CA)?

How CA works and What Happens

Certificate Authority (CA) is a trusted third-party auditor that validates the company behind a domain name – making sure it exist –  and/or validates ownership of domain, before issuing a digital certificate, that is used as a proof of identity online.

Certificate Authorities (CAs) typically work through channel partners to provide better outreach and local support to end customers. 

One such example is the DigiCert-Cyber Secure Asia Alliance Partnership.

Behind ‘DigiCert-Cyber Secure Asia’ Order Procedure

(1) After an initial consultation with Cyber Secure Asia (CSA), security administrators in South East Asia can place DigiCert certificate orders through CSA.

(2) These orders get sent immediately to DigiCert.

(3) Security administrators would then need to submit a Certificate Signing Request (CSR) according to their server type.

(4) DigiCert would verify the domain and organisation behind the CSR.

(5) Once verified, DigiCert issues the certificate to CSA.

(6) CSA then delivers this certificate to security administrators and provide local support with regards to installation and SSL endpoint configurations.

What Happens Next?

(7) Upon receiving the digital certificate, the IT security administrator would need to install it onto the server.

(8) Once properly installed and configured, all communication between [client – server] or [server – server] (depending on your requirements) will be encrypted after the client/server checks the certificate root against a list of trusted CAs. Thereby, preventing any unwanted third parties from eavesdropping.

Certificate Authority (CA) thus plays an important role in the entire network security process and is the central authority for certificate issuance. Without CAs, client and servers may not be encrypted and may not be compatible with a wide range of devices.
