+title: 'Ensure PAM Enforces Password Requirements - Prevent the Use of Dictionary Words'
+
+description: |-
+ The pam_pwquality module's <tt>dictcheck</tt> check if passwords contains dictionary words. When
+ <tt>dictcheck</tt> is set to <tt>1</tt> passwords will be checked for dictionary words.
+
+rationale: |-
+ Use of a complex password helps to increase the time and resources required to compromise the password.
+ Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at
+ guessing and brute-force attacks.
+ <br /><br />
+ Password complexity is one factor of several that determines how long it takes to crack a password. The more
+ complex the password, the greater the number of possible combinations that need to be tested before the
+ password is compromised.
+ <br /><br />
+ Passwords with dictionary words may be more vulnerable to password-guessing attacks.

+ To check if dictionary words are disallowed run the following command:
+ <pre>$ sudo grep dictcheck /etc/security/pwquality.conf /etc/pwquality.conf.d/*.conf</pre>
+ The <tt>dictcheck</tt> parameter should be equal to 1. The value should look like
