Description of Safe Web Browsing Mode (SBM)

Safe Web Browsing Mode (SBM) is where the browser can be placed into a mode which will only permit websites from a user’s personal SBM list to be accessed. This mode is intended for the user who wishes to be sure that they are at the intended known, trusted website before they exchange sensitive information. It addresses the needs of several of the use cases brought up in the WSC working group.

What is the relationship to the Australian Trust Network?

The Australian Trust Network is represented on the FSTC Security Committee and aware of the Safe Web Browsing Project. The information of the Australian Trust Network can be easily leveraged as a data source into the Safe Web Browsing Project.
