laptop wifi security in public library, etc., etc.
I recently got a nice, lightly used IBM Thinkpad laptop. It has wireless capability for the Internet. Linux is the only OS in the laptop. At home, I don't have wireless-- I have a wired DSL connection for my laptop and for my IBM desktop (which also only has Linux as OS).
When I took the laptop to the public library, wireless is provided there for free and I had no trouble connecting to the system there. But since I'm new to wireless, what do I need to have installed to have a secure laptop when in the public library (or when I'm anywhere else that offers free wifi) using the wireless connection? [I use Firestarter as my firewall in the laptop and in the desktop.] Do I have to install some software to make sure my laptop is secured from spying and invasions when in the library or is the Firestarter enough? If Firestarter is not enough, what is that wifi security software by name?
[My OS is MEPIS 8.5, a Debian-based distro.]
