03.04.06E Retention of Previous Configurations

Statement

Retain {{ insert: param, A.03.04.06E.ODP.01 }} previous versions of baseline configurations of the system to support rollback.

Guidance

Retaining previous versions of baseline configurations to support rollback includes configuration files for hardware, software, and firmware, configuration records, and associated documentation. This requirement enhances SP 800-171 requirement 03.04.01.

Statement

• (includes preempt) Ensure that the threat event does not have an impact.

  • Reduce likelihood of occurrence and/or reduce likelihood of impact.

  • The adversary’s efforts or resources cannot be applied or are wasted.

• (includes exert) Make it more difficult for threat events to cause adverse impacts or consequences.

  • Reduce likelihood of impact and reduce level of impact.

  • Adversary activities are restricted in scope, fail to achieve full effect, do not take place in accordance with adversary timeline, or require greater resources than adversary had planned.

• (includes shorten and reduce) Restrict the consequences of realized threat events by limiting the damage or effects they cause in terms of time, system resources, and/or mission or business impacts.

  • Reduce level of impact and reduce likelihood of impact of subsequent events in the same threat scenario.

  • The adversary’s effectiveness is restricted.

Assessment objective
