NIST SP 800-53r5 Compliance

NIST and Supply Chain Risk Management

The National Institute of Standards and Technology Special Publication 800-53 (NIST SP 800-53) is a framework for security and privacy controls for information systems and organizations.

Considered the foundation upon which all other cybersecurity controls are built, the latest version, NIST SP 800-53 publication Rev. 5, expands and refines supply chain security and privacy guidelines by establishing an entirely new control group, SR-Supply Chain Risk Management.

Relevant Requirements

  • Emphasize security and privacy through collaboration in identifying risks and threats, and through the application of security and privacy-based controls

  • Require transparency of systems and products (e.g., lifecycle, traceability, and component authenticity)

  • Increase awareness of the need to pre-assess organizations, and to ensure visibility into issues and breaches

  • Use formal risk management plans and policies to drive the supply chain management process

SP 800-53r5 Supply Chain-Specific Controls How Prevalent Helps

CA-2 (2) Control Assessments | Specialized Assessments

Organizations can conduct specialized assessments, including verification and validation, system monitoring, insider threat assessments, malicious user testing, and other forms of testing.

CA-2 (3) Control Assessments | Leveraging Results from External Organizations

Organizations may rely on control assessments of organizational systems by other (external) organizations.

Prevalent delivers a large library of pre-built templates for third-party risk assessments – including those specifically built around NIST controls. With Prevalent, you can conduct assessments at the time of supplier onboarding, contract renewal, or at any required frequency (e.g., quarterly or annually) depending on material changes in the relationship.

Assessments are managed centrally and backed by workflow, task management, and automated evidence review capabilities to ensure that your team has visibility into third-party risks throughout the relationship lifecycle.

Importantly, Prevalent includes built-in remediation recommendations based on risk assessment results to ensure that your third parties address risks in a timely and satisfactory manner and can provide the appropriate evidence to auditors.

As part of this process, Prevalent also continuously tracks and analyzes external threats to third parties. Prevalent monitors the Internet and dark web for cyber threats and vulnerabilities, as well as public and private sources of reputational sanctions and financial information.

All monitoring data is correlated with assessment results and centralized in a unified risk register for each vendor, streamlining risk review, reporting, remediation and response initiatives.

Prevalent also incorporates third-party operational, reputational, and financial data to add context to cyber findings and measure the impact of incidents over time.

If required, you can analyze SOC 2 reports or ISO Statement of Applicability in place of a vendor’s risk assessments. Our service reviews the list of control gaps identified within the SOC 2 report, creates risk items against the third party, and tracks and reports against deficiencies over time.

CP-2 (7) Contingency Plan | Coordinate with External Service Providers

Coordinate the contingency plan with the contingency plans of external service providers to ensure that contingency requirements can be satisfied.

IR-4 (10) Incident Handling | Supply Chain Coordination

Coordinate incident handling activities involving supply chain events with other organizations involved in the supply chain.

  • Clear roles and responsibilities (e.g., RACI)
  • Third-party inventories
  • Risk scoring and thresholds based on your organization’s risk tolerance

With Prevalent, your team can continually evaluate the effectiveness of your TPRM program according to changing business needs and priorities, measuring third-party vendor key performance indicators (KPIs) and key risk indicators (KRIs) through the relationship lifecycle.

PM 30 (1) Supply Chain Risk Management Strategy | Suppliers of Critical or Mission-Essential Items

Identify, prioritize, and assess suppliers of critical or mission-essential technologies, products, and services.

Prevalent quantifies inherent risks for all third parties. Criteria used to calculate inherent risk for third-party prioritization includes:

  • Type of content required to validate controls
  • Criticality to business performance and operations
  • Location(s) and related legal or regulatory considerations
  • Level of reliance on fourth parties
  • Exposure to operational or client-facing processes
  • Interaction with protected data
  • Financial status and health
  • Reputation

From this inherent risk assessment, your team can automatically tier suppliers; set appropriate levels of further diligence; and determine the scope of ongoing assessments.

PM-31 Continuous Monitoring Strategy

Develop an organization-wide continuous monitoring strategy and implement continuous monitoring programs that include:

a. Establishing organization-wide metrics to be monitored;

b. Establishing defined frequencies for monitoring and assessment of control effectiveness;

c. Ongoing monitoring of organizationally-defined metrics in accordance with the continuous monitoring strategy;

d. Correlation and analysis of information generated by control assessments and monitoring;

e. Response actions to address results of the analysis of control assessment and monitoring information; and

f. Reporting the security and privacy status of organizational systems to defined personnel.

Continuously track and analyze external threats to third parties with Prevalent. We monitor the Internet and the dark web for cyber threats and vulnerabilities, as well as public and private sources of reputational risks, sanctions, and financial information.

Monitoring sources include:

  • Criminal forums; onion pages; dark web special access forums; threat feeds; and paste sites for leaked credentials — as well as several security communities, code repositories, and vulnerability databases
  • Databases containing several years of data breach history for thousands of companies around the world

All monitoring data is correlated with assessment results and centralized in a unified risk register for each vendor, streamlining risk review, reporting, remediation, and response initiatives.

Once all assessment and monitoring data is correlated into a central risk register, Prevalent applies risk scoring and prioritization according to a likelihood and impact model. This model frames risks into a matrix, so you can easily see the highest impact risks and can prioritize remediation efforts on those.

Then, you can assign owners and track risks and remediations to a level acceptable to the business.
