    As far as I know, sniffing is referred as listening to the internet traffic. When your on a wired network there has to be a physical intrusion or some software has managed to install on a PC.

    Sniffing on a wireless network can't be prevented. Therefore all traffic is encrypted between router and the wireless card in your PC. Encryption with a 10-12 digit password phrase will make it difficult to crack the encryption code

    On the internet there is http and https (secure). HTTPS is called secure because it is encrypted also, this helps to protect against sniffing (somewhere in the network) also.

    A FW's primary function is to drop all irregular/unsollicitated/non-protocol packets. This means it keeps out messages from the network reaching your PC. Adding a sniffer like snort helps to find out any irregularities. This is because most intrusions have a certain pattern (e.g. for a key logger to have any effect, it has to send the data to some IP address on the internet to be used by someone else).

    A Firewall will help prevent intruders entering in to your computer when the FW also has an HIPS element. On a wired PC, there needs to be some software installed to be 'sniffed'. This is where the HIPS of the FW helps to protect you. On a wireless network anyone can 'sniff' the traffic. A Firewall with HIPS can prevent your PC being 'sniffed' as you call it. But no software firewall can prevent the wireless network traffic being sniffed

    no need for useless tools in such cases

    Yep, agreed. Without WPA2 or similar, I don't know how you can prevent wireless sniffing, unless you and others somehow encrypt locally everything that is broadcast on the wireless network.

    You would need Tor, or a VPN.

    I know that about TOR, but are you 100% sure that Comodo Trust Connect will protect me against sniffer in a OPEN wireless network?

    thanks.

    Yes. This a VPN network / connection run by COMODO. Please read the information on the link.

    even if it is a VPN still it's not so secure, just read what comodo says> Comodo: We have logs of all system connections

    Hi,

    Logs concerns more Privacy than Security...
    Being naked in the jungle and looking for 100% security...let's be serious: you can't imagine the number of tools that provide ways to steal your cookies, logs ID/passwords, rediredirects your browsers etc...It's impossible from a host to control what happens on the network!
    But there is many countermeasures that helps in mitigating the risks.
    -system and browser hardening: firefox is well armored, especially with extensions like NoScript and Certifcate Patrol:
    https://addons.mozilla.org/en-US/firefox/addon/certificate-patrol/
    -SSL VPN is necessary: No need to pay for Comodo as there is ways to use some service for free: http://dnslookup.me/free-vpn/
    AnchorFree is well known even with ADs (that can be easily stopped), and IPIG can also be mentioned: http://www.iopus.com/iPig/
    -safe practises: use Windows virtual keyboard (OSK.exe), do not let any session open (web mail for instance) remove cookies immediately after, use bookmarks instead of typing the address or following a link etc...

    And of course, this question can't be solved and totally circumscribed by a few words...

    hm, ok but here is a tricky question to all you that knows much about this,
    if let's say my brother has the software sniffer ON and the wireless is NO protection it's open wireless but i make it fast with wpa2 just for 30 minutes,

    And then that software sniffer he is using and can see all what i am doing, then i typed password and WPA2, then can he see what i am doing on those 30 min or not after i made it as WPA2 secured ?

    Tor will encrypt your internet traffic and there will be nothing to sniff there but encryption. His brother will not know what websites he is going to..

    If you use a VPN, anything that connects to the internet is encrypted, from your computer on out. There is nothing to sniff but encryption.
