03.01.10E Object Security Attributes

Statement

Use {{ insert: param, A.03.01.10E.ODP.01 }} associated with {{ insert: param, A.03.01.10E.ODP.02 }} to enforce {{ insert: param, A.03.01.10E.ODP.03 }} as a basis for flow control decisions.

Guidance

Organizations implement information flow control policies and enforcement mechanisms to control the flow of CUI between designated sources and destinations within systems and between connected systems. Flow control is based on the characteristics of the information and/or the information path. Enforcement occurs, for example, in boundary protection devices that employ rule sets or establish configuration settings that restrict system services, provide a packet-filtering capability based on header information, or provide a message-filtering capability based on message content. Information flow enforcement mechanisms compare the security attributes associated with information (i.e., data content and structure) and source and destination objects and respond appropriately when the enforcement mechanisms encounter information flows that are not explicitly allowed by information flow policies. Security attributes can also include source and destination addresses employed in traffic filter firewalls. Flow enforcement using explicit security attributes can be used, for example, to control the release of certain types of information. This requirement enhances SP 800-171 requirement 03.01.03.

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.03.01.10E.ODP.01 }} associated with {{ insert: param, A.03.01.10E.ODP.02 }}, {{ insert: param, A.03.01.10E.ODP.03 }}, and {{ insert: param, A.03.01.10E.ODP.04 }} are used to enforce {{ insert: param, A.03.01.10E.ODP.05 }} as a basis for flow control decisions.
