NIST 800-171 compliance

Maytech’s information security management system (ISMS) is compliant with NIST 800-171 and is certified with the international standard ISO 27001:2013 for which we are audited twice a year by Lloyd’s Register Quality Assurance, one of the leading business assurance providers globally.

This article explains the NIST 800-171 standard and the corresponding areas of the international standard for information security ISO 27001. Skip to the end for a breakdown of areas which do not map directly, but which Maytech is compliant with.

Further information is available on our Nist 800-171 compliance data sheet.

What is NIST 800-171?

NIST 800-171 guidelines were developed by the National Institute of Standards of Technology, a non-regulatory agency of the United States Department of Commerce.

Their purpose is to provide recommendations on security controls for information systems at companies dealing with federal agencies, thus helping them ensure compliance with HIPAA, SOX, and other related US regulations.

While not an international standard, this set of recommendations is, in fact, a US equivalent to ISO 27001.

Proving compliance with NIST 800-171

ISO 27001 and NIST 800-171 both cover the same areas of information security, but there are differences in the way they are implemented, so one does not precisely map to the other. A process of clarification is required to demonstrate compliance, depending on which standard you are operating under.

Similarities Between NIST 800-171 and ISO 27001

Even though NIST 800-171 and ISO 27001 have some differences, there are lots of similarities between the two. While NIST 800-171 is designed specifically for non-Federal (commercial) enterprises, with a separate set of guidelines – NIST 800-57 – developed to cover Federal systems and organisations, ISO 27001 is a more general standard and can be applicable to organisations of all types.

Both NIST 800-171 and NIST 800-57 can be mapped to each other, as well as the international ISO 27001 standard in the key control areas, including:

  • Authorise Access to Security Functions
  • Non-Privileged Access for Non-security Functions
  • Auditing Use of Privileged Functions
  • Automated Monitoring / Control
  • Protection of Confidentiality / Integrity Using Encryption
  • Managed Access Control Points
  • Authentication and Encryption
  • Full Device / Container-Based Encryption
  • Portable Storage Devices
  • Publicly Accessible Content
  • Role-Based Security
  • Processing Failures
  • Configuration Settings
  • Device Identification and Authentication
  • Password-Based Authentication
  • Incident Monitoring
  • Cryptographic Protection
  • Risk Assessment
  • Vulnerability Scanning
  • Voice over Internet Protocol
  • Protection of Information at Rest
  • Security Alerts, Advisories, and Directives
  • Inbound and Outbound Communications Traffic

Indirect Mappings: ISO 27001 to NIST 800-171

Appendix D of the NIST 800-171 (Revision 1) publication maps each requirement statement against the equivalent control in ISO 27001.

There are some NIST 800-171 requirements which have no direct mapping, or the equivalent ISO 27001 control has an asterisk against it, indicating that the ISO control “does not fully satisfy the intent of the NIST control”. For each of these areas, Maytech is compliant and can provide further details for each of the specific areas on request.

Please see the table below containing details of the specific differences, taken from Appendix D of NIST 800-171:
