Dangerous Internet, Be Safe

The Internet can be a pretty dangerous place with nasties lurking round every corner. While you are enjoying the benefits of Internet shopping, subscription websites, free downloads and Internet banking, there are unscrupulous people out there just waiting to pounce.Hackers, fraudsters, identity thieves and many others would love to get hold of your personal details or take hold of your computer. What stands between you them and certain disaster?

A little knowledge!
1)Here's a few tips to keep relatively safe, remember, most of these people are looking for easy targets so don't make yourself one..

Your password
1)Avoid the obvious and never use dictionary words, these can be brute forced in minutes.

2)Names, DOB or any other forms of personal information can be easily guessed so avoid them too.

3)A secure password is one which is over 8 chars long, contains UPPER and lower case letters and has non alphabetical characters such as $ ^ - " etc.

4)A good example would be F$a4%Cm*--d32.

5)Now this may seem difficult to remember and you are right, it is, you could devise a formula in your mind to remember yours.

6)In the long run it may save you a whole lot of trouble.

7)You may want to use a secure password storage facility if you have many passwords like this.

Secure your PC
1. Make sure you have a firewall installed. Many hackers scan IP addresses for ports that host known access points into your PC, a firewall can hide these and the hackers won't even know you are there. If you are invisible to them then what can they do to harm you?

2. Have an Anti-Virus application running at all times and make sure it is scheduled to update itself daily. These cannot protect you from unknown viruses but a virus that has been doing the rounds for a day or more will be detected by "most" AV applications. Some run on what is called heuristics and can detect new Viruses of similar designs..

3. Keep your Operating System up to date. Hackers are always finding new ways of breaking into an O/S. When they do, the O/S manufacturers release a patch to make sure the hackers cannot get in, always update your O/S and make sure you are fully patched against any new holes into your system.

Be wary of email
1)If you receive an email from someone you don't know, asking you to download a greetings card, a PD F file or visit a site, then beware. Check it over carefully, do you know this person, were you expecting something like this?

2)If the website address they are asking you to visit looks like this then it is more than likely to be a site hosting malware's, just itching to exploit your computer and fill it full of nasty. Sometimes they will try to fool you be using a dynamic redirect or simply by making the link as text, Click here to see my photos hover the mouse over the link and see where it leads. If it looks suspicious then do not click on it.

3)Check over all files sent to you, if what looks like a PDF/Word/Excel file lands in your in box and it ends in .exe .com .scr .pif (there are many more but these are some of the most common) then avoid it like the plague, these are executable files and more than likely to contain a virus/worm/Trojan just waiting for you to launch it.

You may even receive email from a colleague which contains a virus, someone may have hijacked/spoofed their email address and sent you a very plausible message, laden with viruses. Always have a think. Were you expecting it? Is the attachment an executable one? Does the link look dubious in any way?

Watch what you download
Peer 2 Peer (P2P) applications such as Lime wire, Kazza and e mule are FULL of viruses, if you use these programs then always check the following.

1. If you are downloading music, say an mp3, make sure it has the mp3 extension (nirvana.mp3). Never download a music file that has .exes .zip .com .pif .scr etc. Nirvana.exe = BAD NEWS.

2. Movies, the same goes. I will include a list of extensions to watch out for.

3. Applications. NEVER download an application using Peer 2 Peer, hackers regularly update their viruses and launch them on P2P and many of them will easily avoid your Anti Virus, 90% of applications on P2P are laden with viruses.

4.If you follow these tips, and are always on the lookout, aware of what you are doing, downloading, browsing etc then you should be relatively safe. These things should come to you naturally after time and just be a daily part of your safe Internet experience.
