LinkedIn defends Intro security

Last week professional networking service LinkedIn introduced a new service called Intro, which works on your iPhone and in conjunction with your e-mail account to provide you with instant details about the people you're communicating with, linking to their LinkedIn profiles. In fact, it reroutes your mail account through LinkedIn's own systems. That's raised red flags as a potential security problem. Now LinkedIn is taking to the Internet to allay fears that Intro users are at risk.

Cory Scott, LinkedIn's senior manager of Information Security, has made a blog post explaining how Intro works.

From network hardening and isolation to bringing in a third-party security consulting firm, Scott says that LinkedIn does whatever it can to make sure that Intro is secure.

When mail flows through the LinkedIn Intro service, we make sure we never persist the mail contents to our systems in an unencrypted form. And once the user has retrieved the mail, the encrypted content is deleted from our systems.

Scott calls the negative comments made thus far "misconceptions" and "purely speculative." But is that enough? What do you think? Are you nervous about Intro's security? Or have you already starting using it? Please let me know in the comments.
