IP address spoofing involving the use of a trusted IP address can be used by network intruders to overcome network security measures, such as authentication based on IP addresses. It does not provide information on the identity of the sender or the computer being used. It may provide general information on the region, city and town when on the packet was sent. The source IP address provides only limited information about the sender. The protocol requires the receiving computer to send back a response to the source IP address therefore spoofing is mainly used when the sender can anticipate the network response or does not care about the response. The source IP address is normally the address that the packet was sent from, but the sender's address in the header can be altered, so that to the recipient it appears that the packet came from another source. The protocol specifies that each IP packet must have a header which contains (among other things) the IP address of the sender of the packet. ![]() The basic protocol for sending data over the Internet network and many other computer networks is the Internet Protocol (IP). ![]() In computer networking, IP address spoofing or IP spoofing is the creation of Internet Protocol (IP) packets with a false source IP address, for the purpose of impersonating another computing system.

This way, when a host is compromised (e.g. Client certificates are like long, authority-signed passphrases which are different for every client device. In addition to passphrases, it can use certificates on client and AP. WPA2 Enterprise works similar to WPA2-PSK, but uses a dedicated authentication server. (There is also an attack called Hole 196 that can be used by already authenticated attackers to break the session key of other authenticated hosts with the AP, but this is not relevant here.) WPA2 Enterprise networks Hence, a long, not-guessable PSK is necessary. A weak PSK could also be guessed in a brute-force attack, e.g. On the other hand, everyone who knows the PSK could fake a WPA2-AP. Your device will not associate with that AP unless it uses the same PSK.ĪFAIR, this is also valid for authentication with WPA version 1 and even WEP, but those protocols have other weaknesses which make them non-recommendable or even useless. Thus, a rogue WPA2-AP cannot give access to a client by just having the right SSID and accepting any password from the client. When using WPA2 authentication with pre-shared keys (PSK), both the station and the AP have to prove that they know the PSK in the four-way handshake. WPA2 networks with pre-shared keys (WPA-PSK) The rogue access point (AP) will then see all traffic your device sends or receives over this network (but cannot look into HTTPS or VPN encrypted traffic, of course). Anyone can spoof a well-known "Some Coffeemaker Free WiFi" and your device will happily connect to it when encountered. When a Wi-Fi network is unencrypted (like most "Free Wi-Fi" networks in cafés, bars or hotels) and you have already been connected to that network once before, your device will automatically reconnect to a network with the same name. What happens next will depend on the kind of Wi-Fi network. its SSID), it will try to reconnect, if that network's security method matches the saved one. When your device comes near a network it "knows" (by its name, i.e. But it depends on the network.įirst, most Wi-Fi devices will remember all Wi-Fi networks they connect to, and also whether that network is encrypted or not and using which method.
