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:

• CFG-04.3_A01 the period of inactivity after which the system initiates a session lock is defined.
  Defined parameters: fifteen (15) minutes
  Assessment rigor: 1
  Origin: 171A_3.1.10[a]
• CFG-04.3_A02 access to the system and viewing of data is prevented by initiating a session lock after the defined period of inactivity.
  Assessment rigor: 1
  Origin: 171A_3.1.10[b]
• CFG-04.3_A03 previously visible information is concealed via a pattern-hiding display after the defined period of inactivity.
  Assessment rigor: 1
  Origin: 171A_3.1.10[c]
• CFG-04.3_A04 the time period of expected inactivity or description of when to log out is defined.
  Defined parameters: When inactivity is anticipated to exceed Fifteen (15) minutes. For privileged users, it is also the end of a user's standard work period.
  Assessment rigor: 3
  Origin: 53A_R5_AC-02(05)_ODP
• CFG-04.3_A05 users are required to log out when organization-defined time period of expected inactivity or description of when to log out.
  Defined parameters: When inactivity is anticipated to exceed Fifteen (15) minutes. For privileged users, it is also the end of a user's standard work period.
  Assessment rigor: 3
  Origin: 53A_R5_AC-02(05)
• CFG-04.3_A06 the time period of inactivity after which a device lock is initiated is defined (if selected).
  Defined parameters: fifteen (15) minutes
  Assessment rigor: 2
  Origin: 53A_R5_AC-11_ODP[01] 53A_R5_AC-11_ODP[02] 171A_R3_A.03.01.10.ODP[02]
• CFG-04.3_A07 access to the system is prevented by <A.03.01.10.ODP[01]: SELECTED PARAMETER VALUES>.
  Defined parameters: initiating a device lock after “at most 15 minutes” of inactivity and requiring the user to initiate a device lock before leaving the system unattended
  Assessment rigor: NIST 800-171
  Origin: 53A_R5_AC-11a. 171A_R3_A.03.01.10.a
• CFG-04.3_A08 the device lock is retained until the user reestablishes access using established identification and authentication procedures.
  Assessment rigor: 2
  Origin: 53A_R5_AC-11b. 171A_R3_A.03.01.10.b
• CFG-04.3_A09 one or more of the following PARAMETER VALUES are selected: {a device lock is initiated after <A.03.01.10.ODP[02]: time period> of inactivity; the user is required to initiate a device lock before leaving the system unattended}.
  Defined parameters: at most 15- minute time period
  Assessment rigor: NIST 800-171
  Origin: 171A_R3_A.03.01.10.ODP[01]
