When installing software or hardware that requires a username and password, make certain that you use a secure username and password. In particular, always change the default settings and use a strong password.

Default settings

New hardware is frequently supplied with a default username and password already set up.

  • When you install new hardware with default settings, change both the username and the password immediately. Those credentials will be widely known, and will pose a security risk.
  • You should also change preset credentials when installing software.

Strong passwords

Strong passwords are a vital part of network security. A strong password is one that:

  • is at least seven characters long
  • contains a mixture of letters, numerals and symbols
  • does not contain a commonly used word or name.

The default security policy in Windows XP Professional and Windows 2003 restricts the use of accounts which have a blank password.
