Passwords – User Security

In this article we will discuss Passwords – User Security, will make brief discussion on Passwords – User Security, In last article we discuss about Endpoint Security.

To protect network devices, it is important to use strong passwords. Here are standard guidelines to follow:

  • Use a password length of at least 8 characters, preferably 10 or more characters. A longer password is a better password.
  • Make passwords complex. Include a mix of uppercase and lowercase letters, numbers, symbols, and spaces, if allowed.
  • Avoid passwords based on repetition, common dictionary words, letter or number sequences, usernames, relative or pet names, biographical information, such as birthdates, ID numbers, ancestor names, or other easily identifiable pieces of information.
  • Deliberately misspell a password. For example, Smith = Smyth = 5mYth or Security = 5ecur1ty.
  • Change passwords often. If a password is unknowingly compromised, the window of opportunity for the attacker to use the password is limited.
  • Do not write passwords down and leave them in obvious places such as on the desk or monitor.

On Cisco routers, leading spaces are ignored for passwords, but spaces after the first character are not. Therefore, one method to create a strong password is to use the space bar and create a phrase made of many words. This is called a passphrase. A pass phrase is often easier to remember than a simple password. It is also longer and harder to guess.
