5.5.7 Ensure multi-factor authentication is enable for users - pam_pkcs11

Information

The operating system must uniquely identify and must authenticate organizational users (or processes acting on behalf of organizational users) using multi-factor authentication.

Rationale:

To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system.

Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and processes acting on behalf of users) must be uniquely identified and authenticated to all accesses, except for the following:

Accesses explicitly identified and documented by the organization. Organizations document specific user actions that can be performed on the information system without identification or authentication;

and

Accesses that occur through authorized use of group authenticators without individual authentication. Organizations may require unique identification of individuals in group accounts (e.g., shared privilege accounts) or for detailed accountability of individual activity.

Solution

Configure the operating system to require individuals to be authenticated with a multifactor authenticator.
Enable smartcard logons with the following commands:

# authconfig --enablesmartcard --smartcardaction=0 --update
# authconfig --enablerequiresmartcard -update

Modify the /etc/pam_pkcs11/pkcs11_eventmgr.conf file to uncomment the following line:
Example: vim /etc/pam_pkcs11/pkcs11_eventmgr.conf
Uncomment the following line:

/usr/X11R6/bin/xscreensaver-command -lock

Note: Modify the /etc/pam_pkcs11/pam_pkcs11.conf file to use the cackey module if required.
