Accessing a wireless connection from a coffee shop or airport terminal may be convenient and even fun, but you should note that public access points (frequently called hot spots) are often insecure.
The following are some steps you should consider taking before connecting to a public access point:
1. Use a virtual private network (VPN) if possible.
2. Avoid using passwords and providing personal information to web sites while connected to public access points.
3. Encrypt your files.
4. Be aware of your surroundings.
