The system must prevent the use of dictionary words for passwords.

Rule version SOL-11.1-040190 · STIG v3 · 2026-08-19

Discussion

The use of common words in passwords simplifies password-cracking attacks.

Check

Check /etc/default/passwd for dictionary check configuration.

# grep ^DICTION /etc/default/passwd

If the DICTIONLIST or DICTIONDBDIR settings are not present and are not set to:

DICTIONLIST=/usr/share/lib/dict/words DICTIONDBDIR=/var/passwd

this is a finding.

Determine if the target files exist.

# ls -l /usr/share/lib/dict/words /var/passwd

If the files defined by DICTIONLIST or DICTIONBDIR are not present or are empty, this is a finding.

Fix

The root role is required.

# pfedit /etc/default/passwd

Insert the lines:

DICTIONLIST=/usr/share/lib/dict/words DICTIONDBDIR=/var/passwd

Generate the password dictionary by running the mkpwdict command.

# mkpwdict -s /usr/share/lib/dict/words
