Supply chain risk management policy and procedures address the controls in the SR family as well as supply chain-related controls in other families that are implemented within systems and organizations. The risk management strategy is an important factor in establishing such policies and procedures. Policies and procedures contribute to security and privacy
SR-2control
The dependence on products, systems, and services from external providers, as well as the nature of the relationships with those providers, present an increasing level of risk to an organization. Threat actions that may increase security or privacy risks include unauthorized production, the insertion or use of counterfeits, tampering, theft, insertion of mal

Supply chain elements include organizations, entities, or tools employed for the research and development, design, manufacturing, acquisition, delivery, integration, operations and maintenance, and disposal of systems and system components. Supply chain processes include hardware, software, and firmware development processes; shipping and handling procedures

Every system and system component has a point of origin and may be changed throughout its existence. Provenance is the chronology of the origin, development, ownership, location, and changes to a system or system component and associated data. It may also include personnel and processes used to interact with or make modifications to the system, component, or

The use of the acquisition process provides an important vehicle to protect the supply chain. There are many useful tools and techniques available, including obscuring the end use of a system or system component, using blind or filtered buys, requiring tamper-evident packaging, or using trusted or controlled distribution. The results from a supply chain risk

An assessment and review of supplier risk includes security and supply chain risk management processes, foreign ownership, control or influence (FOCI), and the ability of the supplier to effectively assess subordinate second-tier and third-tier suppliers and contractors. The reviews may be conducted by the organization or by an independent third party. The r

The establishment of agreements and procedures facilitates communications among supply chain entities. Early notification of compromises and potential compromises in the supply chain that can potentially adversely affect or have adversely affected organizational systems or system components is essential for organizations to effectively respond to such incide

Anti-tamper technologies, tools, and techniques provide a level of protection for systems, system components, and services against many threats, including reverse engineering, modification, and substitution. Strong identification combined with tamper resistance and/or tamper detection is essential to protecting systems and components during distribution and
SR-10control
The inspection of systems or systems components for tamper resistance and detection addresses physical and logical tampering and is applied to systems and system components removed from organization-controlled areas. Indications of a need for inspection include changes in packaging, specifications, factory location, or entity in which the part is purchased,
SR-11control
Sources of counterfeit components include manufacturers, developers, vendors, and contractors. Anti-counterfeiting policies and procedures support tamper resistance and provide a level of protection against the introduction of malicious code. External reporting organizations include CISA.

Data, documentation, tools, or system components can be disposed of at any time during the system development life cycle (not only in the disposal or retirement phase of the life cycle). For example, disposal can occur during research and development, design, prototyping, or operations/maintenance and include methods such as disk cleaning, removal of cryptog

To implement supply chain risk management plans, organizations establish a coordinated, team-based approach to identify and assess supply chain risks and manage these risks by using programmatic and technical mitigation techniques. The team approach enables organizations to conduct an analysis of their supply chain, communicate with internal and external par

Diversifying the supply of systems, system components, and services can reduce the probability that adversaries will successfully identify and target the supply chain and can reduce the impact of a supply chain event or compromise. Identifying multiple suppliers for replacement components can reduce the probability that the replacement component will become

Controls that can be implemented to reduce the probability of adversaries successfully identifying and targeting the supply chain include avoiding the purchase of custom or non-standardized configurations, employing approved vendor lists with standing reputations in industry, following pre-agreed maintenance schedules and update and patch delivery mechanisms

To manage supply chain risk effectively and holistically, it is important that organizations ensure that supply chain risk management controls are included at all tiers in the supply chain. This includes ensuring that Tier 1 (prime) contractors have implemented processes to facilitate the "flow down" of supply chain risk management controls to sub-tier contr

Knowing who and what is in the supply chains of organizations is critical to gaining visibility into supply chain activities. Visibility into supply chain activities is also important for monitoring and identifying high-risk events and activities. Without reasonable visibility into supply chains elements, processes, and personnel, it is very difficult for or

Tracking the unique identification of systems and system components during development and transport activities provides a foundational identity structure for the establishment and maintenance of provenance. For example, system components may be labeled using serial numbers or tagged using radio-frequency identification tags. Labels and tags can help provide
