I'm not sure I understand the above question, so I'll leave it to others, in the hope they grasp your meaning. No offence intended. > 2. How do i know if i m secured from hackers? (Note: "Hacker" is a term of admiration towards a particularly clever programmer. Despite insulting abuse of the word by the popular press, it does not refer to a criminal specialty. I'll consider your question to have been rephrased, accordingly.) Determining for certain that you're secured from intruders is a difficult and subtle problem. For comparison's sake, imagine that we were talking the question of whether intruders had invaded your house: You might look for signs of entry. You might check the contents of your jewel box. You might check to see if your belongings are now for sale on eBay and your personal secrets being talked about and laughed at on Slashdot. You could look for graffiti spray-painted on your bedroom wall. But it's conceivable that someone might have very carefully broken into your house and left no traces that you're capable of finding. The situation with intruders into your network and computer hosts isn't very different, except that it's a little worse, in that an intruder's "taking" something doesn't leave a theft-sized hole in your belongings.

If you consult a medical doctor and say "I'm a tuberculosis sufferer. Because of my incessant coughing, I can't seem to hold jobs in restaurants. How can I improve my career prospects?", he'll probably recommend that you go to a sanitarium and get cured. If you ask a Linux mailing list about your problems with Microsoft Outlook or Microsoft Outlook Express, you'll probably be advised to switch to a decent mailer. http://linuxmafia.com/~rick/linux-info/applications-muas -- Cheers, "Don't use Outlook.
