Process from Vendor to Validation The figure below illustrates the interactions that happen between Vendor, CST Lab, and CMVP. The MIP list indicates one of fives steps in the process for each validation. Each step is addressed in the figure and the legend below. For more information, please refer to Section 4 of the Management Manual.  The steps for the cryptographic module validation life cycle include: Step 1 - IUT. The vendor submits the cryptographic module for testing to an accredited CST laboratory under a contractual agreement. Cryptographic module validation testing is performed...

Welcome to the NIST SP 800-53 Public Comment Website   The NIST SP 800-53 Public Comment Site was developed to ensure that the SP 800-53 control catalog provides the most comprehensive and up-to-date set of controls/countermeasures to manage security, privacy, and supply chain risk. By modernizing the NIST comment process and moving to an online dataset instead of following a document-based update process, NIST can provide its stakeholders the most up-to-date controls in multiple data formats to manage risk while encouraging use of automation.  Stakeholders can provide feedback on...

The NIST SP 800-53 Controls Public Comment Site was developed to ensure that the SP 800-53 control catalog provides the most comprehensive and up-to-date set of controls/countermeasures to manage security, privacy, and supply chain risk. By modernizing the NIST comment process and moving to an online dataset instead of following a document-based update process, NIST can provide its stakeholders the most up-to-date controls in multiple data formats to manage risk while encouraging use of automation.  Stakeholders can provide feedback on controls by: submitting a "proposal" for a new...

General Questions and Background What is the purpose of the SP 800-53 Public Comment Website? NIST believes that robust, widely understood, and participatory development processes produce the strongest, most effective, most trusted, and broadly accepted standards and guidelines. The following principles guide NIST's standards and guidelines development: Transparency: All interested and affected parties have access to essential information regarding standards and guidelines-related activities throughout the development process. Openness: Participation is open to all interested...
