Spoofing is the obtaining of information by faking the own identity. In IT-Security a distinction is drawn between:
- IP Spoofing, Address Spoofing (Allegation of a wrong IP address)
Countermeasure: packetfilter
- DNS Spoofing (Interspersing of a wrong IP assignment into the DNS communication system - Cache Pollution)
Countermeasure: digital signature while exchanging DNS entries
- ARP Spoofing (Interspersing of a wrong IP-MAC assignment in the Ethernet; overwriting by push technique)
Countermeasure: Replacing the ARP cache with a list saved in a file.
- RIP Spoofing (Redirecting of the Data streams by interspersing wrong routing information)
Countermeasure: Set the right kernel parameter
- WWW Spoofing (URL rewriting, man in the middle attack)
Countermeasure: Check the certificates of encrypted connections
