^M
Multifactor solutions that require devices separate from information systems gaining access include, for example, hardware tokens providing time-based or challenge-response authenticators and smart cards such as the U.S. Government Personal Identity Verification card and the DoD Common Access Card.^M
^M
A privileged account is defined as an information system account with authorizations of a privileged user.^M
^M
Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless.^M
^M
This requirement only applies to components where this is specific to the function of the device or has the concept of an organizational user (e.g., VPN, proxy capability). This does not apply to authentication for the purpose of configuring the device itself (management).^M
^M
Requires further clarification from NIST.^M

@shawndwells Is there a OCSP responder that ships with Red Hat (besides the one in openssl hopefully)?

If so, shouldn't we be required to enable that for all local systems to restrict the amount of outbound traffic from systems?

@shawndwells Yes, any service that uses PKI should be configured to use either an OCSP or SCVP responder. Any service that does not support this capability should not be used.

Is there an IPA and/or dogtag configuration guide since it appears to be a required infrastructure capability?
