Spoofing

Attacker masquerades as someone else by providing false data. Phishing has become the most common form of Web page spoofing. Another form of spoofing is URL spoofing. This happens when an attacker exploits bugs in your Web browser in order to display incorrect URLs in your browser location bar. Another form of spoofing is called “man-in-the-middle”. This occurs when an attacker compromises the communication between you and another party on the Internet. Many firewalls can be updated or configured to significantly prevent this type of attack.
