Wireless security

Post by 12Wesley » Thu Feb 25, 2010 8:37 am

My wireless connection may not be secure

I use wireless at work provided by another company. I am considered
a customer thus this service is provided. I'm the only on the
router if that matters. Recently the router was changed
from a linksys to a buffalo. At that time the company removed
a wired LAN cable I was using. He insisted to set my
network up on the router. Which I did to keep him off my
machine. My work is confidental I have switched to a gsm coonection
however the company is removing the gsm repater tower due
to a service issue.
Sorry for the long post. What can I do to be secure
and prevent spying on the supplied network
that I don't control. Not sure if this is possible

thanks
Wesley

Not quite sure I understand you fully - there are so many "strange" ways to connect
I would recommend a Deny setting in Gufw and then use a VPN
I would always recommend a VPN as internet is inherently insecure

Sorry for the confusion I gave too much background info

basically I want to connect to the Internet (wireless/wired) securely,
when using a public Internet connection. In this case the person
suppling the Internet connection will signicantly gain from targeting
my laptop.

I used a VPN called hotspot shields when in windows what is a good
VPN for mint

I'm new to Linux What is gufw?

When using a VPN can an attacker get into my system before it is
tunneled to a 'secure' machine?

Thanks for your assistance so far

Sorry - GUFW is the "firewall" application included by default - just type guf in an open menu
I don't know all that much about VPN but you should use a VPN and inside the tunnel use encryption
A VPN does not use encryption by default
In the Network Manager applet you find a tab for VPN
