03.11.12E Automated Means for Sharing Threat Intelligence

Statement

Employ automated mechanisms to maximize the effectiveness of sharing threat intelligence information.

Guidance

To maximize the effectiveness of monitoring and sharing threat intelligence information, it is important to know what threat observables and indicators the sensors need to be searching for. By using well-established frameworks, services, and automated tools, organizations improve their ability to rapidly share and feed the relevant threat detection signatures into monitoring tools. 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 negate) 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 detect) Reduce risk due to ignorance of threat events and possible replicated or similar threat events in the same or similar environments.

  • Reduce likelihood of impact.

  • The adversary loses the advantage of stealth as defenders are better prepared by developing and sharing threat intelligence.

Assessment objective

automated mechanisms are employed to maximize the effectiveness of sharing threat intelligence information.

Assessment method

• Information security program plan threat awareness program policy threat awareness program procedures risk assessment results related to threat awareness documentation about the cross-organization information-sharing capability other relevant documents or records

Assessment method

• Personnel with information security program planning and plan implementation responsibilities personnel responsible for the threat awareness program personnel responsible for the cross-organization information-sharing capability personnel with information security responsibilities external personnel with whom threat awareness information is shared by the organization

Assessment method

• Processes for implementing the threat awareness program processes for implementing the cross-organization information-sharing capability automated mechanisms supporting and/or implementing the threat awareness program automated mechanisms supporting and/or implementing the cross-organization information-sharing capability
