how does internet security work?

A financial transaction on the internet can be routed through any number of systems throughout the world before its destination.  At any of these points, a sniffer can be checking the data for number sequences common to credit cards and expiry dates. If these numbers are extracted they could potentially be used by someone other than yourself.   It is therefore necessary to make sure that your data is protected during it's journey.\n\nTo protect your data a secure server is used.  The secure server works in conjunction with your browser.  When your send your order, the browser scrambles the data.  The data  passes through the internet and is unscrambled by the secure server. During the data's journey it will not be recognizable by any third party and as such is secure.  \n\nA secure server uses a special protocol called https instead of the more familiar http. When in use the URL will be preceded by https:.  To support a secure socket layer (SSL), the sever must have a "certificate" signed by a company called Verisign.  The servers used by Flexisoft have this certificate. \n\nThis method of security is not just used for shopping carts but also used by financial institutions who now allow you to "Bank-on-line"\n\nBrowsers\n\nYour browser must support SSL.  Either Microsoft® Internet Explorer 4.0 or higher OR Netscape Navigator® 4.0 or higher, support secure transactions.  To download the latest version of the either of these browsers select the icons below.

They can monitor EVERYTHING you do. Every site you visit, every keystroke in fact if you are at work now they know what you just typed. Keep in mind, they can and will have all your passwords as well. I have a program called Remote Administrator that allows me to sit here and watch my kids on their pc from my pc as if I was standing there.

A secure website uses a method of encryption to transfer data across the Internet.\n\nWebsites can either be fully or partially secured or completely unsecured.  \n\nWeb pages that are used for general browsing are usually not secured whilst pages which may be used to transmit sensitive information (such as credit card details or personal information) are generally secured.

hmm, this probably won't work buy you can try lowering the security level of your internet browser, maybe then it would work.

Basically, nowhere. Mostly, nobody's in charge of policing your experience.  \n\nIn most of the Western world, no one is in charge of making your Internet experience the way you imagined it would be, or would prefer it to be. In fact, nowhere of which I'm aware is that true. In some places the government or the local religious establishment will attempt to filter the entire Internet to keep out things that they don't like, but that might not be your choice. For instance, the Wikipedia is basically unavailable in mainland China (except through somewhat involved trickery involving proxies), and so someone there is trying to start something similar just for mainland China -- it's said to be very heavily censored by the Chinese government. \n\nAside from political or religious information some people might not want you to encounter, there are jerks and idiots (commercial and otherwise) on the 'Net and you will come across them or their works. Pretty much like real life, ritgh? \n\nMany of these are out to take your money (with or without supplying a product, any product, in return) and are little different any other grifter or con artist. They can just get at you more easily than they used to. The really dangerous stuff is probably the spoof sites which try to fool you into supplying user name, account number, password, PIN, and other such information by pretending to be, for instance your bank, or Yahoo administration, or AOL Adminstration, etc. It's called 'phishing'. It's one of the ways identity theft can happen, and only you can block it by never supplying such information until you are CERTAIN the site you're interacting with is the correct one. Call your bank and ask, look at the URL (in the address bar in your browser) to see if it looks suspicious, and if it is, go to the site yourself by typing in the address on the invoice (or something like that) rather than clicking on some link in a dodgy email or Web page. Never supply any such information routinely, without thought. Always ask yourself if all looks right. Always, no exceptions. Cynicism is good.\n\nClicking on 'unsubscribe' in junk email usually only has the effect of confirming that their email has reached a real person, and you will likely get even more spam as your email address is passed around. It's now more valuable than before since it's been shown to actually work. \n\nComplaining to your ISP moves the responsibility to someone who never agreed to handle your censorship for you. And is not equipped to do so. In the US, ISP's are legally protected from the consequences of, for instance, passing illegal images (eg, child porn) only if they are neutral with regard to the traffic they carry. \n\n========\nfilter programs\n\nIn any case, there are no good automatic programs which can do this correctly. Nor are there any laws which can do the same. Legislation, like programs which attempt such things, is too blunt an instrument, aside from the fact that much of this junk is produced elsewhere (regardless of where you are) and your legislature won't have jurisdiction. \n\nFor instance, let's say that sex stuff is the sort of thing you want blocked. The content of the stuff that heads your way might be inspected for trigger words (you can imagine what some of them might be) and those pages blocked. Unfortunately, you will likely not be able to see any Web sites having to do with breast cancer research because it will trip one of the triggers. Libraries, schools, and parents  have tried install such 'nanny' software with quite uneven results for just this reason. It's very hard -- acutally hard, not merely a nuisance -- to reliably screen out the unwanted stuff, while not also blocking wanted stuff. At least not automatically. \n\nAnother filtering approach is to block all traffic from particular sites (eg, anoyingpornRus.com) or from particular 'Net addresses for such things as emai

You may have heard the term firewall before but have you ever wondered how does a firewall work and why do I need one? A computer firewall protects your computer by putting up a barrier to keep anyone from accessing your files when you are surfing the Internet.\n\nOnce a hacker get access to your files malicious codes spread through your computer retrieving your personal information that the hacker can use to steal your identity or charge items with your credit card numbers. So how does a firewall work?\n\nA firewall not only stops this from happening but keeps the malicious file out of your computer so it can't spread to your other files. That's why it's called a firewall because its job is similar to a firewall that keeps a fire from spreading from one area to the next.\n\nIf a hacker tries to invade your computer files to get your passwords and credit card numbers you've used for online purchases he simply can't get access. Computer firewall software will allow good data in but blocks all bad data from entering your computer.\n\nGood data is when you are surfing the Internet, visiting web sites, downloading photos or data files. But bad data, like hacker programs, or anything that spies on your Internet habits without your knowledge is not allowed.\n\nWhen computer firewall protection is enabled, everything that goes in and out of your computer is monitored. With the amount of malicious programs on the Internet today it's also a way to prevent spyware and adware from getting into your computer.\n\nMany people think that the anti-virus software that came with their computer protects them from hackers. While it's important to keep anti-virus software updated for viruses it does nothing to secure your computer against direct hacker attacks.\n\nWhether you have a dial-up, cable, broadband or DSL connection, every minute that your computer is connected to the Internet, it is at risk. Hackers are looking to do you harm and even steal your identity. Identity theft is one of the fastest growing crimes today.\n\nOne of the most effective ways to guard your personal information and keep these criminals away from your sensitive passwords and credit card numbers is the use of computer firewall protection.\n\nYou'll hear the term firewall used a lot in the near future because these problems are growing at an alarming rate on the Internet. You'll probably also hear other people ask, how does a firewall work and why do I need one? But now you'll know the answer

Most web sites that sell products online have secure servers.\n\nA web site with a secure server can be identified by the following:\n\nhttps:// appears in front of the address instead of http://\n\nfor example https://www.yahoo.com\n\n\nA padlock icon will appear in the bottom right pane of the main window in Internet Explorer.\n\n\nRight click over the page you are viewing and select properties. In the section marked 'Connection' you will either see Encrypted or Not Encrypted.\n\nSites that say Encrypted are being viewed on a secure server.\n\n\nI hope this answers your question. Remember to vote for me as best answer if you found my answer useful.

Connecting to the Internet without a firewall is like leaving the keys in your car with the engine running and the doors unlocked while you run into the store. Although you may be able to get in and out before anyone notices, someone may take advantage of the opportunity. On the Internet, hackers use malicious code—such as viruses, worms, and Trojan horses—to try to find unprotected computers. A firewall can help protect your computer against these and other security attacks

Get a software firewall for minimum protection; or a hardware firewall (a router works just fine if you've got cable or DSL). Also have a virus program. McAfee and Norton sell 'Internet Security Suites,' with all of these software components built in. Don't forget to update your security programs too.

See, it depends on the kind of Security you have. If you have Internet Explorer 6 or Internet Explorer 7 Beta with Symantec Firewall and Norton Internet Security activated, then the chances of Virus invasion is less. Although you will face some problems surfing net with such a good security, your computer will remain free from spyware and viruses. Therefore, install a browser like Internet Explorer 6 or Netscape Navigator 7 in Windows XP and install Norton Internet Security, Norton Antivirus and Symantec Firewall, and activate them before net surfing. Have a safe browsing.

A firewall can prevent an unautorized hacking. Now a days your antivirus comes along with an firewall. A firewall can definatly prevent to a certain extent. However there is no ways you can be completly safe from the internet.

The data travels in packets, Computer networks transfer data from each other by packets of data. A packet is a unit of data at any layer of the OSI protocol stack. One way hackers gain access to computer networks is by intercepting packets of data that contain information like usernames and passwords (programs that preform this are known as a packet sniffer).\nMore information on packets including how you can see the packets you send and receive from the Internet go to this site.\nhttp://www.ethereal.com/

Anti-virus software, anti-adware and pop-up blocker software are the first line of protection.  In addition, you can also use more secure browsers like Opera or Firefox instead of Internet Explorer.  Finally, what really matters is "best practices".  Don't open email attachments from people you dont't know, same goes to email.  Always visit trusted websites and don't give out your personal info to one and all (especially, your phone number).\n\nMost of the spyware and malware come from suspicious websites (read porn and free download websites).  So use caution while visiting such websites (or don;t visit them at all).  \n\nLast but not the least, is physical security.  Don't leave your laptop at public places away from you.  Always lock it if you want to use rest rooms at the library.  Use passwork protection and shut down the computer when not in use.  Encrypt your data if you can.  Back up your data often, preferably have multiple copies on different types of media.\n\nThese are just ways which you can follow for securing yourself, if you keep practising these for a while, you can stay secure.  There might be a lot of other ways.
