This network employs a technology called SSL filtering which allows your network's administrators to filter out harmful or inappropriate Web content such as viruses and pornography. In order for this technology to work effectively, the network's filtering unit must issue to your computer or mobile device a file called an SSL certificate.
This guide will help you install the SSL filtering certificate for Mac-based browsers which use the operating system's built-in Keychain facility — this includes Safari and Chrome.
First, click the Download Certificate button; this will begin a download of the file to your computer. Visit your domain's portal page to download a certificate. By default, this is https://portal.cipafilter.com.
When the certificate finishes downloading, it will appear in your default Downloads folder. Usually, this can be accessed via the Dock near the Trash icon, or, depending on your browser, it may appear in a dedicated downloads window. Locate the file and click to open it.
(Note: These images show Safari running on OS X 10.8 (Mountain Lion); you may not see exactly the same thing if you are using another browser or a different version of OS X; however, the general process and wording should be the same.)
Opening the file will launch the Keychain Access application; here, you will be asked whether to always trust CIPAFilter certificates. Click Always Trust.
Next, you will be prompted to enter the user name and password you use to log on to the computer; do so, and click Update Settings.
You're done! After entering your password, you can close Keychain Access and continue browsing as usual; in most cases, you will not notice anything different after the certificate is installed.
