Background of SAN Certificate
If you use a standard certificate, you secure only one domain. Those who use more than one domain when running a business over the internet love to benefit from the presence of a Multi-Domain Certificate. This type of certificate is also known as SAN (Subject Alternative Name) Certificate namely a certificate that can secure multiple domains with one certificate. SAN Certificates have gained traction following the release of Microsoft Exchange Server 2007 which uses SAN to simplify server configuration. Somehow, we should also know that the extension of SAN has been around since before 1999 as part of the X-509 certificate standard.
X.509 specifications organize the internet x.509 PKI (Public Key Infrastructure) Certificate which also includes the format of SSL Certificates. Originally SSL Certificate only enabled the designation of a single hostname in the certificate namely Common name. The common name indicates the hostname that SSL Certificate covers. Security error or hostname mismatch error is the result of using the certificate for a website that doesn’t match the common name. X.509 specification enables users to attach an extension to Certificate Signing Request (CSR) and final server certificate.
What Subject Alternative Names Do
- Implementing SSL on Exchange Server 2007 and 2013 can simplify SSL configuration. For your information, SAN Certificates use one IP address which then results in one certificate for one IP address. It then reduces the time and frustration involved in managing multiple certificates which each bound to a unique IP address and running numerous low-level PowerShell commands to get it all working.
- SANs allow a number of domains specified to get protected by a single certificate. aside from that, it also secures hostnames with differing domain name extensions in one SSL Certificate. SAN Certificate can secure both www and non-www domains.
- SAN hosts multiple SSL sites on a single IP address. This is ideal for virtual hosting or cloud hosting where 1 IP Address is allocated per server, Amazon AWS for instance. Traditionally, hosting multiple SSL-enabled sites on a single server requires a unique IP address of each site. Fortunately, SAN or UCC (Unified Communications Certificate) solves that limitation. Microsoft IIS and Apache have the capability of virtual hosting HTTPS sites using the SAN certificate.
