Hide Search Functionality in Customer Portal

Hide Search Functionality in Customer Portal

Hi,

We have the customer portal. We are close to launching this however there is an issue. At the top of the page there is a search box. This search box seems to allow any user to search any records within the system when logged into the portal, regardless of if they are the owner of the record or not. Please can you advise to

A - How to hide this search box as we don't really need it

or

B - How to remove/hide the data that seems to be able to be searched.

Please can you advise on how to do either of these?

Thanks

Jonny
