In other words, WPA only protects from attackers who do not have access to the password. Because of that, it's safer to use Transport Layer Security (TLS) or similar on top of that for the transfer of any sensitive data.
[20] [21] [22] Many wireless access points have security information (if it is factory-secured) and the WPS PIN printed on them; this PIN is also often found in the configuration menus of the wireless access point. If this PIN cannot be changed or disabled, the only remedy is to get a firmware update to enable the PIN to be changed, or to ...
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.
A DHCP client may also request an IP address in the DHCPDISCOVER, which the server may take into account when selecting an address to offer. For example, if HTYPE is set to 1, to specify that the medium used is Ethernet , HLEN is set to 6 because an Ethernet address (MAC address) is 6 octets long.
If router1 routing table does not have any route to 192.168.1.0/24, and PC3 tries to access a resource outside its own network, then the outgoing routing will work until the reply is fed back to router1. Since the route is unknown to router1, it will go to router1's default gateway, and never reach router3.

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.
