Although computer password protection might seem like the geeky stuff of spy movies, password protection is a simple method of computer security. A well-crafted password can go a long way toward protecting the sensitive information on your computer.

Type Of Password Protection
There are various ways to limit access to your computer and the files stored on it. Several of the more popular methods include:

• The front door. You can password protect your computer before it even runs a program by setting a boot password. Many BIOS (Basic Input/Output System) programs allow you to setup a password that must be entered before the operating system will load. Note, however, that if you forget this password it sometimes has to be disabled at the hardware level. Your computer’s user manual will contain details for setting up a BIOS password.
• While you were out. Most major operating systems will allow you to set a password that will restrict access to your computer if it has been inactive for a set amount of time. These passwords are often linked to a screen saver or power management system.
• Keeping your stuff safe. You can also password protect individual files or directories in major computer operating systems. Compressed files (using ZIP or other compression schemes) may be password protected as well. Also, files created with Microsoft Office applications or with OpenOffice can be password protected when they’re saved.

Strong Password Protection
The key to effective password protection is creating strong passwords. Follow these tips to create more secure passwords:

• Long is good. Generally, the longer the password, the more secure it is. Eight characters should be a minimum. For the best protection, think of a short sentence that is easy to remember, like “My dog spot is five.” Removing the spaces from this sentence will create a long, difficult to guess password that is easy to remember.
• It’s a big keyboard — use it. Don’t be afraid to use numbers and punctuation in your passwords. Although substituting a “3” for an “E” is common, there are other less obvious substitutions you can use. Also, don’t forget the random element for extra security.
• Keep it anonymous. Avoid using personal information for passwords. Birth dates, names and other personal information can create easy to guess passwords, so avoid them.
