Title

Apple iOS/iPadOS 27 (MOS) must be configured to enforce a minimum password length of six characters.

Control

Review configuration settings to confirm the minimum passcode length is six or more characters. This procedure is performed in the Apple iOS/iPadOS management tool and on the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the Management tool, verify the Declarative Device Management (DDM) configuration "Passcode" is set to "Minimum length" of "6" or greater. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the profile from the MDM server containing the policy. 5. Tap "Configurations" and then "Passcode". 6. Verify "Minimum length" is listed as "6" or greater. If the minimum passcode length is less than six characters in the MDM server or on the iPhone and iPad, this is a finding.

Discussion

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. The ability to crack a password is a function of how many attempts an adversary is permitted, how quickly an adversary can do each attempt, and the size of the password space. The longer the minimum length of the password, the larger the password space. Having a too-short minimum password length significantly reduces password strength, increasing the chance of password compromise and resulting device and data compromise. SFR ID: FMT_SMF_EXT.1.1 #1

Fix

Install a DDM profile to enforce a minimum passcode length value of six or greater. In the MDM server, in the DDM configuration "Passcode", set "Minimum length" to "6" or greater.
