Description
Multifactor authentication is defined as using two or more factors to achieve authentication. Factors include: (i) Something a user knows (e.g., password/PIN); (ii) Something a user has (e.g., cryptographic identification device, token); or (iii) Something a user is (e.g., biometric). A non-privileged account is defined as an information system account with authorizations of a regular or non-privileged user. Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, Internet). The lack of multifactor authentication makes it much easier for an attacker to gain unauthorized access to a system.

Review DBMS settings, OS settings, and/or enterprise-level authentication/access mechanism settings to determine whether users logging into non-privileged accounts via a network are required to use multifactor authentication. If users logging into non-privileged accounts via a network are not required to use multifactor authentication, this is a finding. (Oracle Advanced Security Option (ASO) may be helpful in meeting this requirement. Notes on ASO Data Integrity follow.) Authentication is used to prove the identity of the user. Authenticating user identity is imperative in distributed environments, without which there can be little confidence in network security. Passwords are the most common means of authentication. Oracle Advanced Security enables strong multifactor authentication with Oracle authentication adapters that support various third-party authentication services, including SSL with digital certificates as well as Smart Cards (CAC, PIV). Oracle Advanced Security provides multifactor authentication to the database. With Oracle Advanced Security, customers can require their users to plug-in a Smart Card (CAC, PIV) as part of their SSL-based authentication to the Oracle Database. Unix and Windows platforms can be checked, by selecting installed products in the Oracle Universal Installer (OUI). Select the Oracle home, and, from Contents tab, drill down to Enterprise Edition Options.

Fix Text (F-57073r1_fix)
Configure DBMS, OS and/or enterprise-level authentication/access mechanism to require multifactor authentication for network users logging into non-privileged accounts. If appropriate, install Oracle Advanced Security Option to support Secure Sockets Layer (SSL) protocols and multifactor authentication through the use of Smart Cards (CAC/PIV).
