Assessment Objectives

In addition to relevant policies, standards and procedures, the assessor shall examine, interview, and/or test to determine if appropriately scoped evidence exists to support the claim that:

• IAC-15_A01 for password-based authentication, a list of commonly used, expected or compromised passwords is maintained and updated frequently and when organizational passwords are suspected to have been compromised directly or indirectly.
  Assessment rigor: 1
  Origin: 53A_R5_IA-05(01)(a)
• IAC-15_A02 for password-based authentication when passwords are created or updated by users, the passwords are verified not to be found on the list of commonly used, expected or compromised passwords.
  Assessment rigor: 1
  Origin: 53A_R5_IA-05(01)(b)
• IAC-15_A03 for password-based authentication, passwords are only transmitted over cryptographically protected channels.
  Assessment rigor: 1
  Origin: 53A_R5_IA-05(01)(c)
• IAC-15_A04 for password-based authentication, passwords are stored using an approved salted key derivation function, preferably using a keyed hash.
  Assessment rigor: 3
  Origin: 53A_R5_IA-05(01)(d)
• IAC-15_A05 for password-based authentication, immediate selection of a new password is required upon account recovery.
  Assessment rigor: 3
  Origin: 53A_R5_IA-05(01)(e)
• IAC-15_A06 for password-based authentication, user selection of long passwords and passphrases is allowed, including spaces and all printable characters.
  Assessment rigor: 3
  Origin: 53A_R5_IA-05(01)(f)
• IAC-15_A07 for password-based authentication, automated tools are employed to assist the user in selecting strong password authenticators.
  Assessment rigor: 3
  Origin: 53A_R5_IA-05(01)(g)
• IAC-15_A08 organization-defined composition and complexity rules for passwords are enforced.
  Assessment rigor: 2
  Origin: 53A_R5_IA-05(01)(h) 171A_3.5.7[c]
• IAC-15_A09 password composition and complexity rules are defined.
  Assessment rigor: 2
  Origin: 171A_3.5.7[a] 171A_R3_A.03.05.07.ODP[02]
• IAC-15_A10 password change of character requirements are defined.
  Assessment rigor: 2
  Origin: 171A_3.5.7[b]
• IAC-15_A11 minimum password complexity requirements, as defined, are enforced when new passwords are created.
  Assessment rigor: 2
  Origin: 171A_3.5.7[c]
• IAC-15_A12 minimum password change of character requirements as defined are enforced when new passwords are created.
  Assessment rigor: 2
  Origin: 171A_3.5.7[d]
• IAC-15_A13 the following composition and complexity rules for passwords are enforced: <A.03.05.07.ODP[02]: rules>.
  Defined parameters: SDP values: (1) Must have a minimum length of 16 characters. (2) Contains a string of characters that does not include the user’s account name or full name.
  Assessment rigor: NIST 800-171
  Origin: 171A_R3_A.03.05.07.f
