Definition: A Router is a telecommunications device that forwards TCP/IP information packets from one network device to another using standard protocols. This specialized equipment can read the data relating to source and destination addresses contained in Internet packets and then determine the most efficient pathway between the two. This device type may be either wired or wireless.

Its Relevance: An organization’s information security policies are both implemented and supported by these network devices which are capable of filtering incoming packets and allowing or denying access. They can also promote a more efficient network infrastructure. Different security challenges exist between the wired and wireless devices that direct network packets.
