However, as with any new development, there are security concerns. In the midst of all this
"openness," how can the social networks keep hackers from stealing the private data contained in the third party programs? An application developed by a third party could be much easier to infiltrate
than a social networking site. At least Facebook's platform is self-contained, enabling it to exercise a good degree of protection over third party programs.
Dan Hubbard, a researcher for the Web security firm Websense says the worst-case scenario is a hacker gaining access to a user's profile and personal data. OpenSocial's greatest asset could also be its greatest weakness: scale-meaning access to many social networks-gives hackers an added incentive because they'd only have to hack one program to gain access to millions of users.
