Vulnerability Discussion

Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased. Multifactor authentication requires using two or more factors to achieve authentication. A privileged account is defined as an information system account with authorizations of a privileged user. The DOD common access card (CAC) with DOD-approved PKI is an example of multifactor authentication.

Check

Verify that RHEL 9 has the openssl-pkcs11 package installed with the following command:

$ sudo dnf list --installed openssl-pkcs11

Example output:

openssl-pkcs.i686 0.4.11-7.el9
openssl-pkcs.x86_64 0.4.11-7.el9

If the "openssl-pkcs11" package is not installed, this is a finding.

Note: If the system administrator demonstrates the use of an approved alternate multifactor authentication method, this requirement is not applicable.

Fix

The openssl-pkcs11 package can be installed with the following command:

$ sudo dnf install openssl-pkcs11
