Wi-Fi - Network Security

Network Security

The main issue with wireless network security is its simplified access to the network compared to traditional wired networks such as ethernet, with wired networking one must either gain access to a building (physically connecting into the internal network) or break through an external firewall. To enable wifi one merely needs to be within the wireless range of the wifi network. Most business networks protect sensitive data and systems by attempting to disallow external access. Enabling wireless connectivity reduces security if the network uses inadequate or no encryption.

An attacker who has gained access to a Wi-Fi network router can initiate a DNS spoofing attack against any other user of the network by forging a response before the queried DNS server has a chance to reply.

Famous quotes containing the words network and/or security:

    A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.
    Jacques Barzun (b. 1907)

    We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.
    John Kenneth Galbraith (b. 1908)
