Protect your Computer
Can you remember all the user names and passwords that you’ve used at every Web site where you’ve ever registered?
I’ll bet you can’t. But it’s no shame not to remember all these things off the top of your head. No one can.
That’s why people write their passwords on Post-It notes and stick them on their monitors. And it’s why Web browsers such as Internet Explorer and Firefox offer to “help you” remember your passwords – which means that anyone who borrows or steals your computer can log on and impersonate you at any of the “memorized” sites.
I posted here, some tips for your safety.
Never share your password with anyone. Not even a relative or colleague. If another person has your password, they can, for all computer purposes, be you. This extends far beyond simply reading your email. In world, this would include sending email as you, gaining access to sensitive financial or health information, and changing where your paycheck goes, and is considered a serious policy violation. But it’s just not a smart thing to do anywhere.
Use strong passwords everywhere. The best defense is a “strong password”. A strong password is a combination of numbers, uppercase letters, lowercase letters, and, if possible, other characters. This makes the password nearly impossible to guess in a reasonable amount of time, and ensures that all the hard work you put into keeping your machine well-defended does not go to waste. The longer the password, the harder it is to guess.
Memorize your passwords or keep them secret. Would you leave the key to your office in the door when you leave? Obviously not. Yet many people leave notes by their desks with their most used passwords or leave their screens unlocked. This leaves the door to your systems available to be unlocked by anyone who discovers its passwords. If you have to write down your passwords, keep them in a secret place. If you have to save your passwords on your computer, avoid giving the file an obvious name, such as ‘my passwords.’
Finnaly, run regular anti-virus scans. If you get malware on your system, it may be programmed to look for passwords either typed in or saved. And it doesn’t hurt to change your passwords every once in awhile too.
