Can I make the database secure?

Can I make the database secure?

creator.zoho.com/findachristianband/findachristianband

I am trying to create a data base for bands.  Just their contact info. I want it assessable for anyone to view, but I don't want it to allow just anyone to post.  I'm afraid of malicious post. Is there a way to make it so I have to approve of a post before it shows up. Or to make it so they email me their info, and only I can post?

I was editing the database in Mozilla, then testing it in Chrome.
 In "set permissions"
Set Permissions, I left all the boxes blank.  Do I need to set it to private?  Is this the wrong app for what I'm trying to do? Can you recommend something better?
