What is an ad hoc network?

A temporary network where devices connect directly to each other without using a central router or access point. Can be open WiFi or a hotspot.

What security issues come with open networks?

Open wifi often does not have encryption, so the data you send and receive is not secure as it can be easily intercepted and read by others.
