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:

• MON-11.1_A01 an authoritative source with which to compare and synchronize internal system clocks is specified.
  Defined parameters: a time server from an Internet time service, with primary and secondary servers selected from different geographic regions
  Assessment rigor: 1
  Origin: 171A_3.3.7[b] 53A_R5_SC-45(01)_ODP[02]
• MON-11.1_A02 internal system clocks used to generate time stamps for audit records are compared to and synchronized with the specified authoritative time source.
  Defined parameters: at least hourly
  Assessment rigor: 1
  Origin: 171A_3.3.7[c] 53A_R5_SC-45(01)(a) 53A_R5_SC-45(01)_ODP[03]
• MON-11.1_A03 system clocks are synchronized within and between systems and system components.
  Assessment rigor: 3
  Origin: 53A_R5_SC-45
• MON-11.1_A04 the frequency at which to compare the internal system clocks with the authoritative time source is defined.
  Defined parameters: at least hourly
  Assessment rigor: 3
  Origin: 53A_R5_SC-45(01)_ODP[01]
• MON-11.1_A05 the internal system clocks are synchronized with the authoritative time source when the time difference is greater than an organization-defined time period.
  Defined parameters: any difference
  Assessment rigor: 3
  Origin: 53A_R5_SC-45(01)(b)
• MON-11.1_A06 time stamps are recorded for audit records that use Coordinated Universal Time (UTC), have a fixed local time offset from UTC, or include the local time offset as part of the time stamp.
  Assessment rigor: 2
  Origin: 171A_R3_A.03.03.07.b[02]
