SSL (secure sockets layer) is a cryptographic protocol for sending secure communications over a network. Essentially SSL works by using digital certificates to specify secured parties and then arranging a “key” to ensure the communication exchanged is encrypted. More details on SSL and how it works can be found here.

One of the ways in which we can ensure SSL is working is by noting the presence of https:// in a web URL. When a user connects to a site with an SSL certificate, the site should resolve successfully to its normal URL with https:// replacing the traditional http://. This indicates that the communication is being done via a secure port, thus limiting the risk of sharing site content, unencrypted, between parties. This security minimizes the ability of phishers and others to execute impersonation attacks on websites.

SSL at NC State

As of 2014, OIT began rolling out SSL certificates for all campus-hosted sites. The decision to apply SSL and to encourage the shift to SSL across all university sites was made for several reasons.

  • Improved security and reliability for campus sites
  • In anticipation of the move to Shibboleth for authentication on all NC State sites
  • Improved search engine ranking by Google and other search engines for secured sites

For more information on getting a certificate for an NC State site please visit the OIT SSL Certificates page, or email

Testing Your SSL Connection

Just because your site resolves to https:// does not mean it does so successfully. Any number of links or site resources used in the building of your website may not be hosted securely, thus causing your SSL connection to be incomplete.
In these instances your site will not resolve to https:// properly, but may degrade to https:// with a marker that the site is using unsecured resources.
Alternately a site without a proper SSL certificate will indicate a failed https:// that might look something like this (right) depending on your browser. In order to correct this problem you will need to work with your web support staff to review the site and find secure sources for all web content.

All campus sites have until November 2nd, 2015 to test and update their sites in order to make them resolve successfully to https://. On November 2nd, the default for campus URLs will change from http:// to https://.

A proper SSL connection
Indicates successful SSL connection.
Unsecured content over SSL
Indicates SSL connection serving unsecured content.
Failed https:// connection
Indicates failed SSL connection.
