03.13.09E Isolation of Security Tools, Mechanisms, and Support Components

Statement

Isolate {{ insert: param, A.03.13.09E.ODP.01 }} from other internal system components by implementing physically separate subnetworks with managed interfaces to other components of the system.

Guidance

Physically separate subnetworks with managed interfaces are useful for isolating computer network defenses from critical operational processing networks to prevent adversaries from discovering the analysis and forensics techniques employed by organizations. This requirement enhances SP 800-171 requirement 03.13.01.

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.

Assessment objective

{{ insert: param, A.03.13.09E.ODP.01 }} are isolated from other internal system components by implementing physically separate subnetworks with managed interfaces to other components of the system.

Assessment method

• System and communications protection policy procedures addressing boundary protection system design documentation system hardware and software system architecture system configuration settings and associated documentation list of security tools and support components to be isolated from other internal system components system audit records system security plan other relevant documents or records

Assessment method

• System/network administrators personnel with information security responsibilities personnel with boundary protection responsibilities

Assessment method

• Mechanisms supporting and/or implementing the isolation of information security tools, mechanisms, and support components
