Symantec ProxySG providing user authentication intermediary services must implement multifactor authentication for remote access to nonprivileged accounts such that one of the factors is provided by a device separate from the system gaining access.
An XCCDF Rule
Description
<VulnDiscussion>For remote access to nonprivileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication is to reduce the likelihood of compromising authentication credentials stored on the system. 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. A privileged account is defined as an information system account with authorizations of a privileged user. Remote access is access to DoD-nonpublic information systems by an authorized user (or an information system) communicating through an external, nonorganization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless. An example of compliance with this requirement is the use of a one-time password token and PIN coupled with a password or the use of a CAC/PIV card and PIN coupled with a password. NOTE: If authentication with client side verification is enabled, it may cause an increase in traffic to the console session and communications lag to the management console. The vendor states this is a known issue which will not likely get resolved until the entire interface has been migrated over to HTML5.

Remediation - Manual Procedure
Configure an approved method of multifactor authentication (such as CAC certificate authentication).
1. Log on to the Web Management Console.
2. Browse to Configuration >> Authentication.
3. Configure at least one multifactor method (such as CAC certificate authentication) per the ProxySG Administration Guide (CAC Certificate authentication configuration is covered in Chapter 52: Certificate Realm Authentication and Chapter 58: LDAP Realm Authentication).
