Install Smart Card Packages For Multifactor Authentication

An XCCDF Rule

Description

Configure the operating system to implement multifactor authentication by installing the required package with the following command: The pam_pkcs11 package can be installed with the following command: 

$ sudo zypper install pam_pkcs11
The mozilla-nss package can be installed with the following command: 
$ sudo zypper install mozilla-nss
The mozilla-nss-tools package can be installed with the following command: 
$ sudo zypper install mozilla-nss-tools
The pcsc-ccid package can be installed with the following command: 
$ sudo zypper install pcsc-ccid
The pcsc-lite package can be installed with the following command: 
$ sudo zypper install pcsc-lite
The pcsc-tools package can be installed with the following command: 
$ sudo zypper install pcsc-tools
The opensc package can be installed with the following command: 
$ sudo zypper install opensc
The coolkey package can be installed with the following command: 
$ sudo zypper install coolkey

Rationale

Using an authentication device, such as a CAC or token that is separate from the information system, ensures that even if the information system is compromised, that compromise will not affect credentials stored on the authentication device.

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.
