When guest access is offered, often it is on a shared network with the network you are attempting to infiltrate. There are several different types of wireless guest access offered, each has its own vulnerabilities:
- Pre-shared keys: These are generally WEP or WPA PSK's that are intended to keep unauthorized users or devices to a minimum. Unfortunately, these keys are generally known by many people and are very rarely changed.
- Captive portal: The guests connect to a wireless network and are automatically redirected to a web page that prompts them for credentials. This may or may not be combined with a pre-shared key.
The most common implementations of guest access include elements of recipes that we have done in previous sections but are stung together and very frequently are labeled as guest networks by their SSID.
