If files are stored in the hard disk, they may be read by others stealing the computer. If files are put in an encrypted disk, others obtaining this disk must type the encryption password before viewing the files. This effectively prevents disclosure of important files.

Security Tips/Takeaways

  • Store sensitive files in an encrypted disk which should be loaded as soon as the power-on password is typed.
  • Place data files of Outlook or Foxmail in the encrypted disk as emails also contain a lot of sensitive information.
  • Set a complex password for the encrypted disk.
  • Use Microsoft’s Bitlocker or TrueCrypt to encrypt a disk.

 

Personal Computer——Weak Password

The more complex a password is, the more difficult it is to crack. As the password complexity grows, the time required for cracking increases exponentially. For example, a simple 6-digit password can be cracked within seconds, while a complex one that contains eight characters requires more than 20 years to be guessed.

Security Tips/Takeaways

  • Use passwords that must be at least 8 characters long and can only contain English letters, digits, and punctuations.
  • Do not include names, birthdate, mobile phone numbers, and license plate numbers in passwords.
  • Change passwords regularly, for example, every three or six months.
