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. Why secure your home router? 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.
Echinoderms live in marine environments that range from the shallow estuarine to the deep sea in tropical to polar latitudes and often play integral roles within the marine ecosystem. As adults, echinoderms are predominantly benthic animals although a few species can swim. Echinoderms are mostly dioecious and primitively develop indirectly through a planktonic, free-swimming, feeding larval stage that lasts from a few days to many months before metamorphosis into a juvenile form (McClay, 2011).
