A cybersecurity incident at a critical supplier can disrupt your business even when your internal security controls are working as intended.

Organizations depend on software vendors, cloud service providers, hardware manufacturers, managed service providers, and other technology partners to support daily operations. Each relationship introduces potential cybersecurity risks that may extend beyond the organization’s direct control.

The challenge is that many organizations still manage supplier cybersecurity through questionnaires, spreadsheets, and periodic reviews. These activities may provide useful information, but they do not automatically create an effective cybersecurity supply chain risk management program.

Organizations need a structured approach that connects supplier risks with business priorities, establishes clear responsibilities, and ensures that identified weaknesses are addressed.

NIST Special Publication 800-161 provides guidance for integrating Cybersecurity Supply Chain Risk Management (C-SCRM) into organizational risk management activities.

It helps organizations establish governance, assess supply chain risks, define security requirements, implement appropriate safeguards, and maintain oversight throughout technology supplier relationships.

In this guide, we explain how to build a practical C-SCRM program using 10 implementation steps, along with examples, assessment criteria, common challenges, and recommendations for maintaining an effective program.

What is NIST SP 800-161 implementation?

NIST SP 800-161 implementation is the process of applying NIST’s cybersecurity supply chain risk management guidance to an organization’s governance, procurement, technology, security, and supplier oversight activities.

The goal is to identify, assess, and manage cybersecurity risks associated with technology products, services, suppliers, and their supporting supply chains.

NIST SP 800-161 Revision 1, titled Cybersecurity Supply Chain Risk Management Practices for Systems and Organizations, provides guidance on integrating C-SCRM into enterprise risk management.

It recognizes that cybersecurity risks can arise throughout the supply chain, including during product development, manufacturing, acquisition, integration, operation, maintenance, and disposal.

Effective implementation therefore requires more than evaluating vendors before signing contracts.

Organizations must understand how supply chain dependencies affect critical business functions and maintain appropriate controls throughout the technology lifecycle.

What does a successful C-SCRM program look like?

A well-structured C-SCRM program should help an organization answer several important questions:

• Which technology suppliers and products support our most important business operations?
• What cybersecurity risks could arise from these suppliers and dependencies?
• Which risks require immediate treatment or additional safeguards?
• Who is responsible for approving suppliers and accepting residual risks?
• How do we monitor supplier security and respond when circumstances change?
• What evidence demonstrates that our C-SCRM activities are being performed?

A mature program connects these questions with documented policies, repeatable assessments, risk treatment decisions, and management oversight.

Why organizations need a C-SCRM implementation plan

Technology supply chains are increasingly interconnected. A business may contract with one cloud provider, but that provider may depend on additional infrastructure providers, software components, subcontractors, and specialized services.

These relationships create dependencies that are not always visible during traditional vendor onboarding.

Supply chain risks extend beyond direct suppliers

A cybersecurity weakness in an upstream software component may affect an organization even when its direct supplier maintains strong security practices.

Similarly, a service outage at a shared infrastructure provider may disrupt multiple business-critical vendors simultaneously.

Organizations need to understand relevant dependencies rather than evaluating each supplier in isolation.

Supplier risks change over time

A supplier may introduce new technology, change its subcontractors, experience a security incident, or undergo an ownership change.

These developments can alter the organization’s risk exposure after the initial assessment.

An implementation plan should establish when supplier risks must be reviewed and which events trigger reassessment.

Procurement decisions influence cybersecurity exposure

Technology purchasing decisions can introduce long-term cybersecurity risks. If security requirements are considered only after a contract is signed, organizations may have limited opportunities to negotiate appropriate safeguards.

Integrating C-SCRM into procurement helps teams evaluate risks before committing to products or services.

Clear governance improves accountability

Cybersecurity supply chain risks often involve multiple departments. Procurement teams manage commercial relationships, security teams evaluate technical risks, legal teams review contractual obligations, and business owners depend on supplier services.

A formal C-SCRM program defines how these teams coordinate decisions and resolve identified risks.

Understanding the NIST SP 800-161 risk management structure

NIST SP 800-161 organizes C-SCRM around three interconnected organizational risk management levels.

Understanding these levels is important because implementation must connect enterprise strategy with business operations and individual technology systems.

Level 1: Enterprise

At the enterprise level, leadership establishes the organization’s overall approach to cybersecurity supply chain risk management.

Activities include defining risk appetite and tolerance, establishing governance responsibilities, approving policies, and allocating resources.

For example, an organization may establish a policy requiring enhanced cybersecurity reviews for suppliers that support critical business functions.

Level 2: Mission and business process

This level focuses on how supply chain risks affect important organizational functions.

Business leaders identify critical services, dependencies, and potential consequences of supplier disruptions.

For example, a financial institution may evaluate how payment processing, customer authentication, and transaction monitoring depend on external technology providers.

Level 3: Operational

The operational level focuses on individual systems, products, services, and supplier relationships.

Activities include conducting assessments, implementing security controls, reviewing technical evidence, tracking vulnerabilities, and monitoring supplier performance.

For example, a security team may evaluate a software vendor’s secure development practices before approving an application for deployment.

How the three levels work together

Risk management level	Main objective	Typical C-SCRM activities
Level 1: Enterprise	Establish strategic direction and risk governance	C-SCRM strategy, policies, risk tolerance, executive oversight
Level 2: Mission and business process	Protect critical organizational functions	Business impact analysis, dependency mapping, supplier criticality
Level 3: Operational	Manage specific supplier and technology risks	Assessments, control implementation, monitoring, remediation

These levels should exchange information continuously. Operational assessment findings should inform business-level risk decisions, while enterprise policies should guide how suppliers and technology products are evaluated.

NIST SP 800-161 implementation: 10 steps to build a C-SCRM program

The following 10-step approach provides a practical implementation roadmap based on NIST SP 800-161 principles.

It is an actionable implementation model rather than a mandatory 10-step sequence prescribed by NIST.

Step 1: Establish C-SCRM governance and executive ownership

The first step is to establish clear responsibility for cybersecurity supply chain risk management.

Without defined ownership, supplier risks may be identified but remain unresolved because no team has authority to approve treatment actions or make risk decisions.

Define leadership responsibilities

Assign executive sponsorship for the C-SCRM program. Depending on the organization, oversight may involve the Chief Information Security Officer, Chief Risk Officer, procurement leadership, or an enterprise risk committee.

Leadership should establish how C-SCRM supports business objectives and how significant supplier risks are escalated.

Establish cross-functional participation

Create a governance structure that includes relevant representatives from cybersecurity, procurement, legal, compliance, enterprise risk management, and business operations.

Each function should have clear responsibilities.

For example, procurement may coordinate supplier onboarding, while security performs cybersecurity assessments and business owners evaluate operational consequences.

Define decision-making authority

Document who can approve suppliers, require additional controls, accept residual risks, and authorize exceptions.

Risk acceptance decisions should be made by individuals with appropriate authority and sufficient information about potential consequences.

Expected outcome: A documented C-SCRM governance structure with defined roles, responsibilities, and decision-making authority.

Step 2: Define C-SCRM objectives, risk appetite, and scope

Organizations should establish what their C-SCRM program is intended to achieve before developing detailed procedures.

The program should reflect business priorities, regulatory obligations, and the organization’s exposure to technology supply chain risks.

Identify the program’s objectives

Common objectives include improving visibility into critical suppliers, reducing exposure to insecure technology products, strengthening procurement controls, and improving resilience against supplier disruptions.

Objectives should be specific enough to guide implementation decisions and performance measurement.

Establish risk criteria

Define how supplier cybersecurity risks will be evaluated. Criteria may include the potential impact on confidentiality, integrity, availability, operational continuity, and applicable legal or contractual obligations.

Organizations should also establish risk tolerance and escalation thresholds.

For example, a critical supplier with access to sensitive customer information may require enhanced review before approval.

Determine the implementation scope

Identify which suppliers, technology products, business functions, and organizational units are included.

An organization beginning its C-SCRM program may prioritize critical technology providers before expanding to lower-risk relationships.

However, the scope should be documented, justified, and reviewed as the program develops.

Expected outcome: A defined C-SCRM program scope, objectives, risk criteria, and approved risk tolerance.

Step 3: Develop a C-SCRM strategy, policies, and implementation plan

NIST SP 800-161 emphasizes integrating cybersecurity supply chain risk management into organizational governance and risk management activities.

A documented strategy helps translate this direction into consistent business practices.

Create the C-SCRM strategy

The strategy should describe the organization’s supply chain risk management priorities, governance approach, and expected outcomes.

It should also explain how C-SCRM aligns with enterprise risk management and information security programs.

Establish supporting policies

Develop policies covering relevant activities such as supplier onboarding, cybersecurity due diligence, acquisition security requirements, risk acceptance, incident reporting, and ongoing monitoring.

Policies should define responsibilities and establish minimum expectations for supplier relationships.

Prepare an implementation plan

The implementation plan should identify activities, accountable owners, required resources, milestones, and success measures.

For example, an organization may establish a phased plan to assess critical suppliers, update procurement procedures, and introduce centralized risk tracking.

Expected outcome: An approved C-SCRM strategy, supporting policies, and a practical implementation plan.

Step 4: Build a supplier and technology dependency inventory

Organizations cannot effectively manage supply chain risks without understanding the products, services, and suppliers they depend on.

A supplier inventory provides the foundation for risk assessments and ongoing oversight.

Identify relevant suppliers

Document cloud providers, software vendors, hardware manufacturers, managed service providers, system integrators, and other technology partners.

Include suppliers that support important systems even when their services are managed by another department.

Record critical supplier information

For each supplier, maintain relevant details such as:

• Supplier name, service description, and business owner.
• Supported systems and business processes.
• Types of information accessed or processed.
• Privileged access or integration requirements.
• Known subcontractors and important dependencies.
• Contract dates, assessment status, and criticality.
• Existing risk findings and treatment activities.

Map important dependencies

Identify where multiple critical business processes depend on the same supplier or underlying technology.

For example, an organization may use several applications that rely on the same cloud infrastructure provider.

Recognizing these dependencies can help identify concentration risks that would otherwise be overlooked.

Expected outcome: A maintained supplier inventory with documented business dependencies and relevant risk information.

Step 5: Classify suppliers based on criticality and risk exposure

Not every supplier requires the same assessment depth or monitoring frequency. A risk-based classification process helps organizations focus resources on relationships that could create the greatest consequences.

Evaluate business criticality

Consider whether a supplier supports essential operations, customer-facing services, sensitive information, or systems that would be difficult to replace.

A provider supporting a critical payment platform may require stronger oversight than a vendor supplying a low-impact administrative application.

Assess cybersecurity exposure

Consider the supplier’s access to organizational systems, data sensitivity, connectivity, software components, and potential attack paths.

Suppliers with privileged access or significant system integration may create additional cybersecurity risks.

Establish supplier tiers

Organizations can create risk tiers to guide assessment requirements.

The following example illustrates a possible classification model.

Supplier tier	Example characteristics	Suggested oversight
Critical	Supports essential operations or processes highly sensitive information	Enhanced due diligence, management oversight, frequent monitoring
High	Significant system access or material business dependency	Detailed cybersecurity assessment and scheduled reassessment
Moderate	Limited system access or moderate operational impact	Standard risk-based assessment and periodic review
Low	Minimal access and limited business impact	Basic screening and reassessment when material changes occur

These categories are illustrative and are not mandatory supplier tiers defined by NIST SP 800-161.

Organizations should establish their own criteria based on business requirements and risk tolerance.

Expected outcome: A documented supplier classification model that determines assessment depth and monitoring expectations.

Step 6: Conduct cybersecurity supply chain risk assessments

Supplier classification helps determine where to focus assessment resources.

The next step is to evaluate the cybersecurity risks associated with relevant suppliers, products, and services.

Assess supplier cybersecurity practices

Review areas such as access management, vulnerability management, incident response, secure development, business continuity, and subcontractor oversight.

Assessment questions should reflect the supplier’s role and the organization’s potential exposure.

For example, a software developer may require detailed questions about development security, dependency management, and software update integrity.

Evaluate product and service risks

Supplier-level assessments should not replace evaluation of the specific products or services being acquired.

A supplier may have a mature security program while a particular product still introduces vulnerabilities or unsuitable dependencies.

Consider product architecture, integration requirements, software components, update mechanisms, and available security assurance evidence.

Review relevant supporting evidence

Organizations may request security policies, independent audit reports, relevant certifications, vulnerability management information, or secure development documentation.

The type of evidence should reflect the supplier’s criticality and the identified risks.

A certification or completed questionnaire should be treated as supporting evidence rather than automatic proof that every supply chain risk has been addressed.

Document assessment findings

Record identified risk scenarios, potential consequences, existing controls, assessment results, and recommended treatment actions.

Use consistent criteria so findings can be compared across suppliers and reported to relevant decision-makers.

Expected outcome: Completed supplier and product risk assessments with documented findings and assigned risk owners.

Step 7: Integrate C-SCRM requirements into procurement and contracts

Supply chain cybersecurity should be considered before an organization commits to purchasing or using technology products and services.

Integrating C-SCRM into procurement helps organizations establish appropriate safeguards before supplier relationships become operational.

Establish security requirements during acquisition

Work with procurement, legal, and security teams to identify relevant cybersecurity requirements.

Depending on the product or service, these may include access controls, secure development practices, vulnerability disclosure, software integrity, and data protection.

Requirements should be proportionate to the identified risks.

Define contractual responsibilities

Contracts may address incident notification, security responsibilities, subcontractor management, audit rights, data handling, service continuity, and termination arrangements.

For example, an organization may require a critical supplier to notify designated contacts about cybersecurity incidents affecting its services.

Contractual requirements should be reviewed by appropriate legal and procurement personnel.

Establish supplier approval checkpoints

Require relevant risk assessments and approvals before high-risk suppliers or products are introduced into critical environments.

Exceptions should be documented and approved through established governance procedures.

Expected outcome: Procurement and contracting procedures that incorporate appropriate cybersecurity supply chain requirements.

Step 8: Implement C-SCRM controls and risk treatment measures

Risk assessments identify potential problems, but implementation requires organizations to take action.

Risk treatment should address the likelihood or consequences of identified supply chain cybersecurity risks.

Select appropriate safeguards

Treatment measures may include stronger supplier access controls, software integrity verification, enhanced monitoring, contractual safeguards, contingency arrangements, or restrictions on certain technologies.

For example, a supplier that requires privileged access to internal systems may need additional authentication, access reviews, and monitoring.

Consider different treatment options

Organizations may decide to reduce a risk, avoid an unsuitable product or supplier, share certain financial consequences through contractual arrangements, or retain a risk through an informed decision.

The selected response should reflect the organization’s risk criteria and applicable obligations.

Assign remediation ownership

Each treatment activity should have a responsible owner, expected completion date, and defined evidence of completion.

Significant findings should be escalated when treatment actions are delayed or residual risks remain above approved thresholds.

Reassess residual risk

After controls are implemented, determine whether the remaining exposure is acceptable.

Risk acceptance decisions should be documented and approved by authorized personnel.

Expected outcome: An actionable risk treatment plan with assigned responsibilities, implemented safeguards, and documented residual risk decisions.

Step 9: Establish continuous supplier monitoring and incident coordination

Supplier risk management does not end after onboarding. Technology providers can experience incidents, introduce new products, change subcontractors, or modify their security practices.

Organizations need processes for identifying relevant changes and responding appropriately.

Define monitoring requirements

Monitoring activities should reflect supplier criticality and risk exposure.

High-risk suppliers may require more frequent reviews of security documentation, open findings, incidents, and significant operational changes.

Lower-risk suppliers may be reviewed less frequently, provided their risk profile remains appropriate.

Establish reassessment triggers

Organizations should identify events that require additional review.

These may include cybersecurity incidents, significant vulnerabilities, ownership changes, new subcontractors, expanded system access, or major changes to delivered services.

For example, a critical cloud provider introducing a new subcontractor that processes sensitive information may require reassessment of relevant data protection and security risks.

Coordinate supplier incident response

Establish communication and escalation procedures for incidents involving technology suppliers.

Define who receives supplier notifications, how business impacts are evaluated, and which teams coordinate containment and recovery activities.

Incident response arrangements should reflect contractual obligations and operational dependencies.

Monitor remediation progress

Track unresolved findings and verify whether agreed treatment measures have been implemented.

Repeated delays or control failures may indicate the need for additional oversight or changes to the supplier relationship.

Expected outcome: A risk-based supplier monitoring process with reassessment triggers, incident coordination procedures, and remediation tracking.

Step 10: Measure C-SCRM performance and improve the program

A C-SCRM program should be reviewed regularly to determine whether it is achieving its objectives.

Organizations need evidence that supplier risks are being identified, treatment actions are progressing, and governance processes remain effective.

Define C-SCRM performance indicators

Useful metrics may include assessment completion rates, unresolved high-risk findings, overdue remediation actions, supplier inventory coverage, and reassessment timeliness.

Metrics should help leadership understand program performance rather than simply measure administrative activity.

Review risk trends

Analyze recurring supplier weaknesses, concentration risks, incidents, and changes in critical dependencies.

For example, repeated findings involving inadequate incident notification procedures may indicate that procurement requirements need improvement.

Evaluate control effectiveness

Review whether implemented safeguards are working as intended.

Evidence may come from security testing, supplier reviews, internal audits, incident analysis, and operational monitoring.

Update policies and procedures

Use assessment findings and performance results to improve the program.

Changes may involve updating supplier classification criteria, refining assessment questions, strengthening contract requirements, or improving escalation procedures.

Expected outcome: A continuously improving C-SCRM program supported by management reporting, performance measurement, and documented reviews.

NIST SP 800-161 implementation checklist

Organizations can use the following checklist to track progress across the 10 implementation steps.

Implementation activity	Key deliverable	Responsible function
Establish governance	C-SCRM governance structure and responsibilities	Executive leadership and risk management
Define objectives and scope	Program scope, risk criteria, and tolerance	Enterprise risk management
Develop strategy and policies	C-SCRM strategy and implementation plan	Security governance and compliance
Inventory suppliers	Supplier register and dependency information	Procurement and IT
Classify suppliers	Risk-based supplier tiering	Third-party risk management
Conduct assessments	Supplier and product risk assessment records	Information security
Integrate procurement controls	Security requirements and approval procedures	Procurement, legal, and security
Implement risk treatment	Treatment plans and residual risk decisions	Risk owners and security teams
Monitor suppliers	Monitoring records, incident procedures, and reassessments	Third-party risk and security operations
Review program performance	KPI reports and improvement actions	Program owner and executive oversight

This checklist provides a practical implementation aid rather than an official NIST certification checklist.

Organizations should adapt it to their business environment, regulatory obligations, and technology supply chain risks.

Example: Building a C-SCRM program for a financial services organization

Consider a financial services organization that depends on several cloud providers, payment technology vendors, customer support platforms, and managed IT services.

The organization already performs vendor onboarding questionnaires, but supplier information is stored across different departments.

Security teams have limited visibility into which vendors support critical business functions, while procurement teams do not consistently involve cybersecurity personnel before approving new services.

Initial C-SCRM assessment

The organization begins by establishing executive oversight and defining its supply chain risk management objectives.

It then creates a centralized supplier inventory and maps important business dependencies.

The assessment reveals that several critical applications rely on the same infrastructure provider.

It also identifies suppliers with privileged system access and incomplete incident notification arrangements.

Risk-based implementation

The organization classifies suppliers according to business criticality and cybersecurity exposure.

Critical providers receive enhanced assessments, while lower-risk vendors follow a proportionate review process.

Procurement procedures are updated to require cybersecurity approval before introducing high-risk technology services.

Contract templates are also reviewed to address relevant security responsibilities and incident notification requirements.

Risk treatment and monitoring

The organization establishes remediation plans for suppliers with significant security weaknesses.

Risk owners are assigned, treatment deadlines are documented, and unresolved findings are reported to management.

High-risk suppliers receive more frequent monitoring, and significant service changes trigger reassessments.

Expected operational improvements

The program gives management a clearer view of critical supplier dependencies and outstanding cybersecurity risks.

It also improves coordination between procurement, cybersecurity, legal, and business teams.

The organization can now make supplier decisions using documented risk information rather than relying only on completed questionnaires.

This example illustrates how NIST SP 800-161 implementation can turn fragmented supplier oversight into a structured C-SCRM program.

Common NIST SP 800-161 implementation challenges

Organizations may encounter practical difficulties when establishing or expanding their C-SCRM programs.

Understanding these challenges can help teams plan more effective implementation activities.

Incomplete supplier visibility

Organizations may not have a complete record of technology suppliers, embedded software components, or subcontractor dependencies.

This can make it difficult to understand the full extent of cybersecurity supply chain exposure.

A maintained inventory and risk-based dependency mapping process can improve visibility over time.

Inconsistent supplier assessments

Different departments may use separate questionnaires, scoring methods, and approval procedures.

This can produce inconsistent results and make enterprise reporting difficult.

Standardized assessment criteria and centralized records help improve consistency while allowing assessments to reflect supplier-specific risks.

Limited resources for supplier reviews

Assessing every supplier with the same level of detail can consume significant time and resources.

Risk-based classification helps organizations focus detailed reviews on relationships that could create the greatest consequences.

Weak remediation accountability

Supplier risk assessments may identify significant weaknesses without establishing who is responsible for addressing them.

Treatment plans should include owners, deadlines, escalation procedures, and documented decisions about residual risks.

Overreliance on annual questionnaires

Annual reviews can provide useful information, but they may not identify important changes occurring between assessment cycles.

Organizations should establish monitoring and reassessment triggers that reflect supplier risk and criticality.

Fragmented documentation

Supplier assessments, contracts, security evidence, and remediation records may be stored in different systems.

This can complicate management reporting, internal reviews, and audit preparation.

Centralized risk and compliance management processes can help organizations maintain more consistent documentation.

How to measure the success of a C-SCRM program

Implementation should be evaluated through measurable outcomes rather than the number of policies or questionnaires completed.

Organizations should select performance indicators that reflect their program objectives and risk exposure.

Recommended C-SCRM KPIs

KPI	What it measures	Why it matters
Critical supplier inventory coverage	Percentage of identified critical suppliers recorded in the inventory	Helps evaluate visibility into important dependencies
Supplier assessment completion rate	Percentage of required assessments completed within the defined period	Measures assessment process execution
High-risk findings overdue	Number of significant findings past their approved deadlines	Highlights unresolved risk treatment activities
Supplier reassessment timeliness	Percentage of required reassessments completed on schedule	Supports ongoing risk oversight
Remediation closure rate	Percentage of treatment actions completed within the reporting period	Measures progress in addressing identified risks
Critical supplier dependency coverage	Percentage of critical business processes with documented supplier dependencies	Supports concentration risk analysis
Supplier incident notification performance	Whether relevant supplier incidents are reported within agreed timeframes	Helps evaluate incident coordination arrangements
Risk acceptance review status	Percentage of applicable risk acceptance decisions reviewed by their required dates	Supports accountability for retained risks

These metrics should be interpreted alongside qualitative findings and the effectiveness of implemented controls.

For example, a high assessment completion rate does not necessarily indicate that supplier risks are being adequately managed if significant findings remain unresolved.

Organizations should review both process performance and actual risk outcomes.

How NIST SP 800-161 works with other NIST frameworks

NIST SP 800-161 does not operate independently of other cybersecurity and risk management guidance.

Organizations can integrate C-SCRM activities with existing programs based on NIST CSF 2.0, NIST SP 800-53, and the NIST Risk Management Framework.

NIST SP 800-161 and NIST CSF 2.0

NIST CSF 2.0 provides a broad structure for managing cybersecurity risks through six functions: Govern, Identify, Protect, Detect, Respond, and Recover.

The framework includes cybersecurity supply chain risk management outcomes under the Govern function, particularly the GV.SC category.

Organizations can use NIST CSF 2.0 to establish their overall cybersecurity governance objectives and NIST SP 800-161 to develop more detailed C-SCRM practices.

For example, an organization may use CSF 2.0 to identify the need for supplier risk governance, then use NIST SP 800-161 to develop supplier assessment procedures, procurement safeguards, and monitoring activities.

NIST SP 800-161 and NIST SP 800-53

NIST SP 800-53 provides a catalog of security and privacy controls for information systems and organizations.

Its Supply Chain Risk Management (SR) control family addresses activities such as supply chain risk management plans, acquisition strategies, supplier assessments, and component authenticity.

NIST SP 800-161 provides additional guidance on applying supply chain risk management practices within organizational risk management activities.

Using these publications together helps organizations connect governance objectives with appropriate security controls.

NIST SP 800-161 and the NIST Risk Management Framework

NIST SP 800-37 describes the Risk Management Framework (RMF), which provides a structured process for managing security and privacy risks throughout the system lifecycle.

Organizations can integrate supply chain risk considerations into RMF activities such as preparing, categorizing, selecting controls, assessing controls, authorizing systems, and monitoring.

This helps ensure that supply chain risks are considered alongside other system security risks rather than managed through an entirely separate process.
