Common Threats, vulnerabilities and mitigation techniques This lesson covers common threats, vulnerabilities and mitigation techniques. One of the wireless threats is WAR driving. WAR driving is when someone drives around looking for an unsecured WiFi network with the intention of breaking in to access confidential and important information.

This is when weaknesses in the encryption key could allow cracking into WiFi.
