Users may be unwilling to add configuration safeguards because configuration seems too difficult or users are reluctant to spend the time with advanced configuration settings. Unfortunately, the default configuration of most home routers offers little security and leaves home networks vulnerable to attack. Small businesses and organizations often use these same home routers to connect to the Internet without implementing additional security precautions and expose their organizations to attack.

Home routers are directly accessible from the Internet, are easily discoverable, are usually continuously powered-on, and are frequently vulnerable because of their default configuration. These characteristics offer an intruder the perfect target to obtain a userâs personal or business data.
The urchin's mouth is located on its underside and its digestive tract ends with the anus located at the top of the sea urchin, relative to the mouth. Similarly to a starfish, the urchin uses the tube feet on its underside to direct food towards the mouth.
In all vertebrates, the mouth is found at, or right below, the anterior end of the animal, while the anus opens to the exterior before the end of the body. The remaining part of the body continuing after the anus forms a tail with vertebrae and spinal cord, but no gut.
