The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [45] Users have been urged to turn off the WPS feature, [46] although this may not be possible on some router models. Also, the PIN is written on a label on most Wi-Fi routers with WPS, which cannot be changed if compromised.
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
In Internet networking, a private network is a computer network that uses a private address space of IP addresses.These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments.
Router2 manages its attached networks and default gateway; router 3 does the same; router 1 manages all routes within the internal networks. Accessing internal resources If PC2 (172.16.1.100) needs to access PC3 (192.168.1.100), since PC2 has no route to 192.168.1.100 it will send packets for PC3 to its default gateway (router2).
A successful ARP spoofing (poisoning) attack allows an attacker to alter routing on a network, effectively allowing for a man-in-the-middle attack.. In computer networking, ARP spoofing (also ARP cache poisoning or ARP poison routing) is a technique by which an attacker sends Address Resolution Protocol (ARP) messages onto a local area network.

A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example:
