    VPN & security

    I have a question regarding VPN and whether it's worth using it. I am often on the internet and security is always a concern. I've recently heard that having a VPN makes it much more secure when using internet. Is it true? I've also heard that some people use a VPN for file sharing (like torrents). Does this mean that, thanks to a VPN, even file sharing is anonymous and that nobody, even their internet providers, can see the traffic that took place?

    Thanks

    It depends on the license, terms of use. That's different with each VPN service. You have to read them. And take a look at reviews on the internet.

    Don't forget that security isn't the same thing as privacy.

    Just throwing that out there.

    the critical point to remember about security is that hackers often -- if not generally -- use un-authorized programming, often know as "malware", -- to compromise their victim

    if you have, for example, a root-kit infecting your PC then nothing in the way of VPNs, or 2-factor passwords, or PGP encryption -- is of any use . the malware becomes your eyes and hands, reading your screen and providing inputs

    a banking trojan for example can wait for you to log into your bank and then use your credentials to transfer all your funds to the Ukraine and then display your screen showing you paid your house payment and your other bills and have the proper balance remaining

    when you get the over-due note from your mortgage company it's too late to recover the money

    this, in my view, is the strongest argument to favor Linux over alternate systems. you may have noticed that with Ubuntu/Linux we normally do not run logged on as "root". --I don't even have the password to log on as root. this is a major difference from other systems -- in which you can do whatever you please.

    i can use sudo to update an app on my system but -- as i understand it -- the scope of the sudo activity will be limited to the terminal session which i use for the install.

    the critical point in computer security is in restricting such software updates. "Approved software only" is the Order of the Day; otherwise you proceed at your own risk

    Re: VPN & security

    I need also some help on this subject. How to install dnscrypt-proxy in a simple way. I have downloaded the package from dnscrypt.org and convert it to .deb but it did not install properly and it is wraped with lock. Is there a good dnscrypt-proxy in deb format. Tanks.

    Your question, if i filtered it right, is: makes using VPN my internet connection saver? And can i use it for filesharing and am i sharing anonymous if i use VPN?

    As said above, your computer is as save as you make it... And a password is as save as you keep/make it! Keeping that in mind...
    (don't stick your password on a paper on the monitor... Yes i've seen it!!!)
    If you set up VPN correctly, i would say YES.

    A VPN encrypts your connection (no-one can look at the data you are sending/recieving, it can be used to stop ISP block) and (most) change your IP (makes it more anonymous)
    Certainly on open networks, and wireless networks i would use VPN.

    Depending on the VPN provider you can use your bittorrent on the VPN to make sharing more safe.
    Keep in mind that it takes a lot more to do save file sharing, like using a ban list, setting up your client the correct way etc. to stay anonymous.
    I am not going to expand on that.

    Now all that said, keeping to the topic, VPN is as safe as you make it, just using VPN doesnt garranty your safe and anonymous.
    VPN has to be set up correctly, use an anonymous email address, pay anonymous and you have to find a secure and good VPN provider (no logs) and set your browser setting correctly. (cookies, history, etc)

    As on advice on VPN, it is very easy to set it up in Ubuntu, i prefer OpenVPN not PPTP, (is fundamentally insecure) there is are several good tuto's on it.
    And after setting up your VPN you need to keep some things in mind, your browser still gives a lot away, opening a movie can give your real ip, as can scripts (Anonymity test see links), watch out for DNSleaks, what provider you choose (see links below) and how you pay...

    Alternative you can use TOR or JonDO, Both free, but slow. NOT for filesharing!
    I like the JonDoFox (gives also firefox profiles) as you can make several Firefox profiles, and choose between TOR and JonDo.

    Usefull Firefox Browser Ad-ons:

    https-everywhere: Always use Https if available! It isnt as good encrypted or as safe as VPN but it is saver than http. (you can use https IN your VPN tunnel).
    Googlesharing: To anonimize your google searches
    No-script : stop scripts
    Cookie monster : manage cookies
    Better privacy : removing lso cookies
    AdBlock+ : Remove annoying adds.

    Usefull links:

    Ow and there is no such thing as free VPN, as in free beer....

    Re: VPN & security

    Uhmmm, a VPN or a proxy server only forwards your connection somewhere else. So while you are in a coffee shop in Praha CZ, your connection appears to be in Scottsdale AZ for example. Apart from that, it does nothing. So, it may protect you against a WiFi sniffer at the next table, but it will do nothing against a sniffer installed on a web site that you are visiting, or on the VPN/proxy server that you are using.

    I think that most people using VPN/Proxy connections will be better served by the Tor Browser Bundle, which costs nothing and results in the same thing:

    A VPN service with openvpn in it, will protect you on open wifi spots, and increases security. Why would TOR do the same?
    VPN services without PPPoE protcol are imho the best.
