Much like in the streets of New York City in "Ghostbusters," suspicious activity is happening in varying degrees all over the web. The relative risk of visiting a website in a "shady" neighborhood can vary dramatically depending on who is managing the "residents" there.

What many users may not realize is that the letters following the "." in a website address represent a top-level domain (TLD) – essentially a "neighborhood" of addresses – maintained by a specific company or group. Ideally, TLDs would all be run by security-conscious operators who diligently review new domain name applications, and reject those that don't meet a stringent set of criteria.

Unfortunately, the reality for many of these new neighborhoods is that they go unpoliced, like Slimer wreaking havoc on the 12^th floor of the Sedgewick Hotel. To avoid getting slimed, businesses and consumers need guidance to understand how safe, or how shady, these new TLDs may be considered for web security purposes.
