03.13.02E Randomness

Statement

Employ {{ insert: param, A.03.13.02E.ODP.01 }} to introduce randomness into organizational operations and assets.

Guidance

Randomness introduces increased levels of uncertainty for adversaries regarding the actions that organizations take to defend their systems against attacks. Such actions may impede the ability of adversaries to correctly target organizational systems that support critical missions or business functions. Uncertainty may cause adversaries to hesitate before initiating or continuing attacks. Misdirection techniques that involve randomness include performing certain routine actions at different times of day, employing different information technologies, using different suppliers, and rotating the roles and responsibilities of organizational personnel. 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. This requirement also depends on the selection of 03.13.03E.

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 deceive) Direct threat events away from defender-chosen resources.

  • Reduce likelihood of occurrence and (to a lesser extent) reduce likelihood of impact.

  • The adversary’s efforts cease.

  • The adversary actions are mistargeted or misinformed.

Assessment objective

{{ insert: param, A.03.13.02E.ODP.01 }} are employed to introduce randomness into organizational operations and assets.

Assessment method

• System and communications protection policy procedures addressing concealment and misdirection techniques for the system system design documentation system configuration settings and associated documentation system architecture list of techniques to be used to introduce randomness into organizational operations and assets system audit records system security plan other relevant documents or records

Assessment method

• System/network administrators personnel with the responsibility to implement concealment and misdirection techniques for systems personnel with information security responsibilities

Assessment method

• Mechanisms supporting and/or implementing randomness as a concealment and misdirection technique
