Passwords that contain only alphanumeric characters are easy to compromise by using publicly available tools. To prevent this, passwords should contain additional characters and meet complexity requirements.
The following table lists the actual and effective default policy values. Default values are also listed on the policy's property page.
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation. Passwords that contain only alphanumeric characters are easy to discover with several publicly available tools.
Configure the Passwords must meet complexity requirements policy setting to Enabled and advise users to use a variety of characters in their passwords. When combined with a Minimum password length of 8, this policy setting ensures that the number of different possibilities for a single password is so great that it's difficult but possible for a brute force attack to succeed.
If the Minimum password length policy setting is increased, the average amount of time necessary for a successful attack also increases. If the default configuration for password complexity is kept, more Help Desk calls for locked-out accounts could occur because users might not be used to passwords that contain non-alphabetical characters, or they might have problems entering passwords that contain accented characters or symbols on keyboards with different layouts.
However, all users should be able to follow the complexity requirement with minimal difficulty. If your organization has more stringent security requirements, you can create a custom version of the Passfilt. For example, a custom password filter might require the use of non-upper-row symbols. Upper-row symbols are those symbols that require you to press and hold the SHIFT key and then press any of the keys on the number row of the keyboard, from 1 through 9 and 0.
A custom password filter might also perform a dictionary check to verify that the proposed password doesn't contain common dictionary words or fragments. However, such stringent password requirements might result in more Help Desk requests. Alternatively, your organization could consider a requirement for all administrator passwords to use ALT characters in the — range. ALT characters outside of this range can represent standard alphanumeric characters that wouldn't add more complexity to the password.
