Types of pen test vary in focus, depth and duration. They can include internal/external infrastructure penetration testing, which assesses on-premise and cloud network infrastructure, wireless penetration testing, which targets an organization’s WLAN, as well as wireless protocols. Other types of tests include web application testing, which assesses websites and custom applications delivered over the web, mobile application testing which tests mobile applications on operating systems, including Android and iOS to identify authentication, authorization, data leakage and session handling issues, and build and configuration reviews which review network builds and configurations.
