Security certificate error with the CIBM intranet website

Contents

Why do I get a 'Security Certificate error' while accessing the CIBM intranet website ?

This is normal, and this is not an attempt to steal informations or hack the network ...

Some parts of the CIBM intranet website uses the HTTPS protocol (secured or encrypted HTTP), to make sure that your username / password wont be send in clear text over the network. In that case, the server should provide a Security Certificate to be identified and to permit encrypted traffic. To be clearly identified, this certificate should be issued by an offical, trusted third-party company, especially for online shops or financial services.

In our case, we just have a self-signed certificate, and this is why your browser shows this kind of error :
