However there are other areas that SSH can offer protection from which can include the following:

• IP Spoofing. This basically prevents someone from pretending to be you. Your IP could be cloned and thousands of files sent out all over the internet, looking like they have come from your machines.
• DNS Spoofing. Where an attack fakes name server records
• Password protection. Where your passwords are intercepted and violated.
• Manipulation. Where data is compromised.
• Protection against attacks where they listen to the X authentication data and use this to gain connection to the X11 server.

SSH works on the proviso of not trusting anybody. Once it is set up it protects all the data that you send from every possible attack.

We all know that as the internet has progressed, scrupulous individuals have taken to hacking and other server compromises. Whilst some of these are just amateurs and hobbyists who do it because they can, there are others who do it to access your data and use it against you or for other non legitimate reasons

Versions of SSH are always being updated to improve on what they offer. If you do have a SSH connection installed then you should ensure that you keep up dated in order to keep your files, data and passwords as secure as possible. There is plenty of information online which gives information on the latest releases available and the extra security features that these process. The first version was released in 1995 so it stands to reason that in the following 15 years the service will have been expanded and improved upon.

There are of course server attacks that SSH cannot protect you against however that is not to say in the future that new SSH versions won’t be able to offer protection against these. For now SSH is the securest way to ensure that your data stays as safe as possible.

Basically it can be set up that as long as an authorized user has internet access they can connect securely through the network and it doesn’t really matter what type of internet connection you have (even slow hotel internet connections will let you connect!)

Once the tunnel is set up and you try to access it, authentication procedures come into place  to ensure that you are authorized to have access to the encrypted data.

Tunnel is basically a networking transportation term that means  a (usually encrypted) one on one connection between two computer applications. It basically ensures the security of the data that you send between two applications like your web browser to a secure host site application. Although it can be used by staff connecting remotely to and office computer or website to catch up on emails or project work, it can be used for personal finance links to financial sites such as banks, sales outlets and private bulletin boards

Basically when we connect somewhere, say to check for email we obviously have to send our log in details to confirm we are who we say we are. By having an SSH secure log in, it means that between the time the password leaves your computer and the time it reaches the other end it is encrypted. This means if anyone does capture your password on the network  during this logon procedure, the encryption should render it unusable.

Setting up a SSH secure tunnel is actually relatively easy but of course the first time you attempt to configure one you may struggle, however once you know how to set it up it can usually be accomplished very quickly. POP3 email is particularly easy to set up and also email clients such as Outlook Express are very easy to configure for connection to an SSH secure tunnel.

All data that you need to transmit via either “intranet” or “internet” needs be secure. These days we send any number of files backward and forward using email or FTP and they often contain secure data that we would not want shared with anyone else. An SSH secure tunnel ensures that whatever you send, however delicate, can be sent safely and securely.

Secure Shell or SSH works in two main ways. Firstly it gives authentication and encryption on any files that you send and secondly it provides compression on these same files. Both of these help you securely send data to another network.

SSH has come on leaps and bounds since it was first discovered back in 1995. The first version of SSH was developed by Tatu Ylonen at the Helsinki University of Technology in Finland. He decided to design something after his university network was compromised by individuals hacking into students passwords. The freeware version was first released in July 1995 and managed to gain over 20,000 in its first 6 months.

Now a days SSH protocol is even more widely used and can be found in software such as UNIX, Microsoft Windows, Apple Mac and Linux.

Reasons that you may need to use SSH include:

-          Replacing RSH to execute single commands on a remote host

-          Replacing Telnet and rlogin to log into a remote host

-          Copying files to a remote host from a local server

-          Alternative to FTP file transfer

-          Tunneling or forwarding a port

-          To securely have a remote server as a file-system on a local computer

These are just some of the reasons that you may have to use an SSH. Thankfully since its development in 1995 it has improved vastly with many more features for a variety of secure data sending reasons.

Sending data across the internet can be risky. Whether it is files, passwords or other data information you could be at risk from hacking attacks. Some of the ways that people hack are like checking for your password, reading your sensitive information, hijacking messages and emails, taking messages and modifying them and many other ways. Of course you must do everything you can to prevent and protect these attacks from happening to your data and by using SSH you can do just that!
