(VPN) The use of encryption in the lower protocol layers to provide a secure connection through an otherwise insecure network, typically the Internet. VPNs are generally cheaper than real private networks using private lines but rely on having the same encryption system at both ends. The encryption may be performed by firewall software or possibly by routers.\n\nLink-level (layer 2 and 3) encryption provides extra protection by encrypting all of each datagram except the link-level information. This prevents a listener from obtaining information about network structure. While link-level encryption prevents traffic analysis (a form of attack), it must encrypt/decrypt on every hop and every path.\n\nProtocol-level encryption (layer 3 and 4) encryption encrypts protocol data but leaves protocol and link headers clear. While protocol-level encryption requires you to encrypt/decrypt data only once, and it encrypts/decrypts only those sessions that need it, headers are sent as clear text, allowing traffic analysis.\n\nApplication (layer 5 up) encryption is based on a particular application and requires that the application be modified to incorporate encryption.

My preferred program is UltraVNC.  It's relatively light, and supports encryption (if security is important).  Very simple to setup, and once you setup, its one click connection to your pc.\n\nIf you want an  easy way to connect them together through routers without port forwarding, try hamachi. It's a zero config vpn program that is always encrypted.  It will make your computers think that they are on the same local area network.

G'day,\n\nConsidering the size of your business, VPN (as suggested by the previous answerers) will be quite a big expenditure for you, since you will need a server, with additional license for Terminal Services and a static IP address with your ISP (Internet Provider) so you can dial-in to your server or workstation anytime anywhere.\n\nProbably the best solution will be to use e-mail and make sure you are using broadband both at home & office to make e-mail traffic faster (since I assume you will have attachments with your e-mails).  I know a document translator who does not have a permanent office, just e-mail and faxes.\n\nHope this helps.  Good Luck :)

Easy answer is NO\n\nYou may try to build VPN to other computer where you have full access, but it won't be easy.

i had to do this myself. if you have windows xp home edition: go under contol panel, then internet options and there will be different taps for security, connections, privacy, content, general, advanced. and you can navigate yourself threw that from there. its pretty self-explanatory and easy.

These are not books but web sites with information on network security issues, \n\nThe Auditor CD that is free from this site has a lot of tools and information on security.\nhttp://www.remote-exploit.org/index.php/Main_Page\n\nNetworking information\nhttp://www.tomsnetworking.com/\n\nA network Monitor Ethereal for looking at packet information in depth.\nhttp://www.ethereal.com/

If you go to about.com they have answers and descriptions about almost anything.  Included is a networking section that will definitely have what you need.  I hope that this helps.

With a virtual private network, you can connect network components through another network, such as the Internet. You can make your Windows Server 2003-based computer a remote-access server so that other users can connect to it by using VPN, and then they can log on to the network and access shared resources. VPNs do this by "tunneling" through the Internet or through another public network in a manner that provides the same security and features as a private network. Data is sent across the public network by using its routing infrastructure, but to the user, it appears as if the data is sent over a dedicated private link.

There are tons of software options - google is your friend there.  Mainly depends on what you have at each site.  For instance, Windows servers all have some sort of software VPN capabilities.\n\nHowever, you can get firewall/routers with VPN endpoint capabilities pretty inexpensively these days.  As an example, the Symantec appliances are simple to use and relatively cheap.  (http://www.symantec.com/small_business/products/security_appliances/sgs300/index.html)  DLink, Linksys and Netgear all have stuff cheaper in the "soho" space as well.  Or spend more and go for Cisco if you have the needs and skills.

If you use a VPN, perhaps to connect to your company or workplace network remotely, that's it.  If there is VMWare Workstation or a similar software suite on your computer, it will show up as this. Basically it is a logical network connection, or a software channel that acts like a physical adapter.

Well, below are some good sites to get basic information about bittorrent from.  I hope they help you out.

About.com usually have articles on setting up WLAN\n\nCNET has some good stuff too.

More details, please... I am totally into Networks.. but i will need info about what and where ur devices located, the tunnel's bandwidth, networking devices, Routers, etc that you have.

Hey! Great question...\n\nWhat you are referring to is a VPN. Typically a VPN consists of a minimum of 2 pieces of hardware, configured to accept each other's incoming traffic and (un)encrypt that traffic. \n\nIf you do NOT already have a firewall on both ends now is the time to get them! A good firewall will provide adequate, secure VPN services as well as NAT/PAT/etc.\n\nThere are so many brands and feature sets I won't recommend a particular one. However, the first things you need to do are:\n1) Become familiar with what a VPN does exactly (look at Cisco's site for a really good primer)\n2) Decide what you want to do with the VPN. If you are looking at just accessing e-mail or simple file transfers that's great. But if you want to get into running applications (such as accessing an Access MDB) over the VPN I think you will be quite disappointed. This is, of course, all dependent on your connection speed.\n3) Research some hardware by looking at both Professional and User reviews (but remember to take them with a grain of salt)(Check out CNET.COM for hardware reviews). Be sure to pay particular attention to the type of encryptions it is capable of using. If you can, get 3DES encryption as it is the current industry standard and is relatively quick so it won't impact performance.\n4) Determine your budget for both ends, and don't forget to include installation costs if necessary for the other end from where you are (if you can't get there easily)\n\nAlso, if you have dedicated Internet connections (such as Frame Relay or other type of T-1) you can call your ISP and ask if they sell a firewall/VPN package that works with your current connection.\n\nI just got through setting up a new VPN for my business so I could work from home, and with a T-1 circuit it's pretty slow. So we use a Remote Control package on dedicated PC's to do most of the work. This way only screen shots, keyboard and mouse controls are being passed. Not only is it blazing fast, but the remote control software adds an additional layer of encryption to the data being passed. Nothing like encrypting your data 5 seperate times for security!\n\nGood look, and welxome to the world of VPN's!

In a nutshell the internet is a massive network of computers with the main players having servers holding stored data. When you download a video from a website it is like retrieving a video from your cd or harddrive except you are downloading it from someone else's cd or harddrive on their server.\n\nSeveral factors keep "things online" online. The server computer holding stored data, telephone or cable companies, and associated electronic gadgets. The server computer needs to on and connected to the internet, the telephone lines need to be open or cable internet operating, and modems and nodes and all the other gadgets need to be in good working order.\n\nThat's it in a nutshell!

Its a set of rules.Like u hav the IP protocol that specifies the format in the internet layer
