Before being able to decide a secure Internet communication system you need to understand the threats to your security. Since the beginning of the Internet there has been a naive assumption on the part of most email users that the only people who are reading their email are the populate they are sending it to. After all with billions of emails and gigabytes of data moving over the Internet every day who would be able to sight their single email in such a fill of data?Wake-up and smell the coffee! Our entire economy is now information based and the majority of that mission critical information is now flowing through the Internet in some form from emails and email attachments to corporate FTP transmissions and instant messages. Human beings especially those strange creatures with a - inal object be for every possible advantage in a dog eat dog world even if that favor includes prying into other peoples' mail or change surface assuming your identity. The privacy of your Internet communications has now become the front line in a assay for the soul of the Internet. The New Generation Packet Sniffers:At the beginning of 2001 most computer security professionals began to become aware of an alarming new threat to Internet security the proliferation of cheap easy to use packet sniffer software. Anyone with this new software a high educate education and communicate find can easily eavesdrop on email messages and FTP transmissions. Software packages such as Caspa 3.0 or PassDetect - Ace Password Sniffer automate the task of eavesdropping to the inform were if you send an email messages over the Internet with the evince "ascribe separate" it's almost a certainty that someone somewhere will interpret it attachments and all.(Caspa 3.0 - from ColaSoft Corporation located in Chengdu. China ,PassDetect - a product whose advertised purpose is to smell passwords sent in email over HTTP or over FTP from EffeTech Corporation. )A good example of this new categorise of software is called MSN Sniffer also from Effetech and it highlights the "party line" openness of today's LAN and Internet environments. Just desire old telephone celebrate lines. MSN sniffer lets you listen-in on other populate's conversations just like picking up another telecommunicate on a celebrate line. On their web place. Effetech advertises MSN Sniffer as:"a handy network utility to capture MSN converse on a network. It records MSN conversations automatically. All intercepted messages can be saved as HTML files for later processing and analyzing. It is very easy to make it to bring home the bacon. Just run the MSN Sniffer on any computer on your communicate and start to interpret. It will preserve any conversation from any PC on the communicate."Just as the Internet has been flooded by a fill of e-mail messages after the introduction of cheap easy-to-use spam generation software the same cause is now taking displace with sniffer software. The study difference is that unlike e-mail. Internet eavesdropping is totally invisible and ten times as - ly. How much of the identity theft being reported today is a enjoin result of Internet eavesdropping? Its hard to express but with the every growing dependency by individuals and corporations on Internet communications opportunities to "interpret" your sensitive data abound. Most FTP transmission are unencrypted!As of November 2003 the majority of corporate FTP transmissions are comfort unencrypted (unencrypted is geek speak for "in the clear" ) and almost all email communications act place "in the clear". Many email and FTP transmissions travel over 30 or more "hops" to make its way from the sender and receiver. Each one of these hops is a displace communicate often owned by a different Internet function Provider (ISP). Any - in the MiddleEven a well run corporation must still primarily believe on trusting its employees contractors and suppliers to consider the privacy of the data flowing over its networks. With the new sniffer technology all it takes is one "idiot in the middle" and your security is compromised. It could be the admin assistant sitting in the cubical next to you or a communicate assistant working for one of the many ISPs your data will jaunt over but somewhere someone is listening. Maybe all he is looking for is his next stock trading idea or maybe he wants to take over your eBay account so he can sell a nonexistent laptop to some unsuspecting "sucker" using your good name its all happening right now at some of the most respected companies in the world. find to your communicate doesn't have to come from a malicious or curious employee-many Internet worms. Trojans and viruses are designed to open up security holes on a PC so that other software can be installed. Once a - er has find to one computer in your communicate or one computer on your ISP's communicate he can then use a sniffer to care for all the merchandise on the network. So I'll password-protect my files alter?You're getting warmer but this comfort isn't going to do the trick. It's a good way to forbid packet sniffers from searching for key words in a register but unfortunately it is not as secure as you might think. If you ever drop a Zip. evince or Excel password don't worry just download the password tool from measure Bit Software www. PasswordTools com it works very well. There are many other packages out on the Internet but Last Bit's drive is the most robust and easy to use if a bit slower that some others. So what can I do about it?OK so now that you understand the threat what can you do about it?Stop using the Internet? - More than a few professionals are returning to telecommunicate calls and faxes for all their important communications. charge to your IT department? - If you have an IT department in your affiliate this is a good displace to start. But did the e-mail send stop when you complained about it to your LAN administrator? Unfortunately he is almost as helpless as you are. Encrypt your communications with PKI etc. - For email this is a bit drastic and can be very expensive especially since you will need to install a key on each PC and coordinate this with the receivers of your email messages your IT organization etc. Use FileCourier - This is by far the easiest and most cost effective way to defend your email attachments or replace FTP transmissions. It takes out the "idiot in the middle" with a very clever solution. The FileCourier come to SecurityI accept that FileCourier is the easiest out-of-the box secure communication system available. FileCourier approaches Internet data transfer security in a unique way. Until FileCourier was first released in December of 2002 all secure email and register transmission systems relied on encrypting the data during the tried and true method of "transfer store and forward". When you send an email it and any documents attached to it are first transmitted to one or more negociate servers. These send server store the documents and then attempt to send it to the receivers email server. To secure the transmission of the email requires either the servers to use extra encryption software technology or forces the individual sender and receivers to lay encryption software and their associated keys or both. Not only is this a costly and measure consuming exercise but it also often fails to defend the data over the complete path of the transmission. What do you do if the receiver is in another company and doesn't have any encryption software installed? What if his affiliate is using a difference encryption standard? Ignoring the complexity of existing secure email and FTP systems.
