Social Engineering and Firewall Subversion
SANS denotes Social engineering as one of the top 4 methods for getting into the internal network and behind the firewall. I would have to agree and rank at least in the top 2 of the 4. Think of it in logical terms. Linkedin tracks your professional background. I look you up on Linkedin and already know your place of business. This is helpful with probing the helpdesk for internal credentials.

If I can foster an email correspondence with anyone at the enterprise, as long as the email isn't aliased, I could possibly have your username. From there facebook could be used to pull personal data and maybe hone down the field of a password possibility if you create your own passwords. With this put into the specialized fields of a dictionary attack, it could take a lot less time to discover your password.

Now account lockouts are the next piece of security that would prevent intrusion. But if I am a hacker I do not want to go on site and try to bypass physical security as well. I would rather try and find an in remotely. Next step for me is to call the helpdesk for remote documentation. Some enterprises have multiple avenues for working remotely. Going back to my previous point about lockouts, the functionality of a remote client is to allow you to work from anywhere. Functionality is the main purpose here. Many don't have a lockout mechanism. So I can try to log in remotely as many times as I want, making my dictionary attack much more efficient. Once I have the credentials. I log in remotely during off hours, and because I don't need to change your password you may not be any the wiser. 

This is all thanks to social engineering.
