Of all of the threats faced by your network security, few are as potentially dangerous as the rogue Access Point (AP). A rogue AP is a WiFi Access Point that is set up by an attacker for the purpose of sniffing wireless network traffic in an effort to gain unauthorized access to your network environment. Ironically, though, this breach in security typically isn't implemented by a malicious hacker or other malcontent. Instead, it's usually installed by someone who is simply looking for the same convenience and flexibility at work that they've grown accustomed to using on their own home wireless network.
