03.13.07E Virtualization Techniques

Statement

Employ virtualization techniques to support the deployment of a diversity of operating systems and applications that are changed {{ insert: param, A.03.13.07E.ODP.01 }}.

Guidance

While frequent changes to operating systems and applications can pose significant configuration management challenges, the changes can result in an increased work factor for adversaries to conduct successful attacks. Changing virtual operating systems or applications, as opposed to changing actual operating systems or applications, provides virtual changes that impede attacker success while reducing configuration management efforts. Virtualization techniques can assist in isolating untrustworthy software or software of dubious provenance into confined execution environments. This requirement does not enhance a specific requirement in SP 800-171 but can be used to strengthen the protection of CUI associated with critical programs or high value assets.

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 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.
