+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.

+    The <tt>dictcheck</tt> parameter should be equal to 1. The value should look like
