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 is, 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 #1a

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. Passwords that contain repeating or sequential characters are significantly easier to guess than those that do not contain repeating or sequential characters. Therefore, disallowing repeating or sequential characters increases password strength and decreases risk. SFR ID: FMT_SMF_EXT.1.1 #1b

The more attempts an adversary has to guess a password, the more likely the adversary will enter the correct password and gain access to resources on the device. Setting a limit on the number of attempts mitigates this risk. Setting the limit at 10 or less gives authorized users the ability to make a few mistakes when entering the password but still provides adequate protection against dictionary or brute force attacks on the password.

Some Bluetooth profiles provide the capability for remote transfer of sensitive DoD data without encryption or otherwise do not meet DoD IT security policies and therefore should be disabled. SFR ID: FMT_SMF_EXT.1.1 #18h

The mobile operating system is required to display the DoD-approved system use notification message or banner before granting access to the system that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Required banners help ensure that DoD can audit and monitor the activities of mobile device users without legal restriction. System use notification messages can be displayed when individuals first access or unlock the mobile device. The banner must be implemented as a "click-through" banner at device unlock (to the extent permitted by the operating system). A "click-through" banner prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating "OK." The approved DoD text must be used exactly as required in the KS referenced in DoDI 8500.01. For devices accommodating banners of 1300 characters, the banner text is: You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details. For devices with severe character limitations, the banner text is: I've read & consent to terms in IS user agreem't. The administrator must configure the banner text exactly as written without any changes. SFR ID: FMT_SMF_EXT.1.1 #36
