Description
FIPS 140-2 precludes the use of invalidated cryptography for the cryptographic protection of sensitive or valuable data within federal systems. Un-validated cryptography is viewed by NIST as providing no protection to the information or data - in effect the data would be considered unprotected plaintext. If the agency specifies that the information or data be cryptographically protected, then FIPS 140-2 is applicable. In essence, if cryptography is required, then it must be validated. Cryptographic modules that have been approved for classified use may be used in lieu of modules that have been validated against the FIPS 140-2 standard. The cryptographic module used must have at least one validated digital signature function. This validated hash algorithm must be used to generate digital signatures for all cryptographic security function within the product being evaluated. Satisfies: SRG-OS-000550, SRG-OS-000530

Who does this work

8 NICE work roles and 7 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-254873r959036_chk)

1. Access the Tanium Server interactively. 2. Log on to the TanOS server with the tanadmin role. 3. Press "A" for "Appliance Configuration Menu," and then press "Enter". 4. Press "A" for "Security," and then press "Enter". 5. Press "X" for "Advanced Security," and then press "Enter". If the FIPS 140-2 setting is currently disabled or persistently disabled, this is a finding.
