Connection question
DeWitch - 27-10-2008 at 16:52

Which PC would be more susceptible to being "hacked"?
PC with direct cable connection (firewalled)
PC with wireless cable connection (also firewalled)

Wireless to cable, by a neighbour or someone sitting in a car nearby.
Apart from the above they are equal in all other cases.

If the direct cable connection gives the PC an internet address (rather than NAT private address) and the WiFi is secured, then the WiFi is less risk.

As T said.

Hardwired, providing it's hooked up to a NAT Router first... If it's Modem to Computer you're only relying on the software firewall to protect you, which isn't ideal really...

Otherwise, WiFi, as it would be going through a NAT Router, thus giving you the protection... (Providing your security measures are set properly.) WPA/WPA2 is much more secure than WEP, and maybe use MAC filtering as well, and if you wanted, hide your SSID.

Thank you all for your help

This does nothing to anyone sniffing for wifi packets.

Every packet your wifi sends out has to, by necessity and design, send the SSID each time.

Hiding your SSID just stops your neighbour (for example) not finding your AP when they do a 'show available wi-fi networks'. It doesn't make it not there.

Hi there :)
How DO you hide the SSID
DuhWitch here;)

Typically you get an option within the wireless setup of your router to do this. Usually it's a tick box.

However, a better option is if you get a good signal in the places you use wireless and your router has the option, then decrease the antenna transmit power - does what it says.

Best bet - make sure you are using WPA2 as a minimum and have a complicated PSK String which you change on a regular basis.

On top of this another option might be to filter by MAC (helps a little) and set your wi-fi mode to the one you use rather than broadcasting all options.

Just a question, ET, would also using a fixed TCP/IP address on each PC in your network and then only permitting those addies through your router also increase security?

YIKES
ummm....
I think it would be easier to just move to where the neighbors were even further away (like in out of sight completely:)
Which we hope to do anyway

Yes and no. IP spoofing is one of the easier tasks that the bogey man undertakes, though what could help is to restrict your dhcp server to the relevant number of devices.

Every step you take does help, but nothing as we find out daily, is impossible to defeat given time.

Thanks for that. When I have more time (unlikely in this lifetime), I may spend more time learning about router security and stuff. Meantime, I have sons who are more than capable of doing this, one of whom actually lives with us for the moment.

Would he like to come to NH for a while????

Where's NH?

If it's somewhere exotic then sign me up :)


LSemmens - 1-2-2009 at 06:55

If you are prepared to pay, I'm sure he would. He needs a new job, as his body is suffering from the job that he is currently doing. He works in Sound, Video and Lighting, doing conferences, concerts and the like. The nature of the industry here is that you don't just operate the desks, you help set up too!

Wish I could:)

Did I mention that he was eligible?

Unfortunately I have no daughters (or sons for that matter) so do not know any young girls since I don't go out much any more.


LSemmens - 3-2-2009 at 11:37

It was worth a try! He seems to have lots of girls who are friends, but has yet to find the perfect lady. I certainly wouldn't try and play "match maker", he reminds me of me when I was younger.

It is good to have friends of the opposite sex too:)
I had several male friends when I was younger, of course many of the other girls hated me for it :D

I had a friend who also liked 'puters, we'd get on the phone and talk for hours. One evening, she rang and on of my sons answered the phone and the yelled out "dad, it's your girlfriend on the phone". We had a good laugh about it, she is stilll "my girlfriend" although we don't often talk these days.
