I have a web application and Internet users update my database via that web application (it's nothing to do with credit cards or something else. It's just important data to my Internet users). If I'd like to offer more security to my users for their database-update process, what kind of security certificates (like "ISO9000") do I have to implement? Or is there "something" that just buying from Verisign will solve that issue?
Can anyone explain me something else about it?
