O19C-00-019800 - Oracle Database must, for password-based authentication, verify that when users create or update passwords, the passwords are not found on the list of commonly used, expected, or compromised passwords in IA-5 (1) (a).

Information

Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication (MFA). Long passwords or passphrases are preferable over shorter passwords. Enforced composition rules provide marginal security benefits while decreasing usability. However, organizations may choose to establish certain rules for password generation (e.g., minimum character length for long passwords) under certain circumstances and can enforce this requirement in IA-5(1)(h). Account recovery can occur, for example, in situations when a password is forgotten. Cryptographically protected passwords include salted one-way cryptographic hashes of passwords. The list of commonly used, compromised, or expected passwords includes passwords obtained from previous breach corpuses, dictionary words, and repetitive or sequential characters. The list includes context-specific words, such as the name of the service, username, and derivatives thereof.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

If any user accounts are managed by Oracle, develop, test, and implement a password verification function that enforces DOD requirements.

Configure the password verify function to verify when users create or update passwords, that the passwords are not found on the list of commonly-used, expected, or compromised passwords in IA-5 (1) (a).

Oracle supplies a sample function called ORA12C_STRONG_VERIFY_FUNCTION. This can be used as the starting point for a customized function. The script file is found in the following location on the server depending on OS:

Windows:
%ORACLE_HOME%\\RDBMS\\ADMIN\\catpvf.sql

Unix/Linux:
$ORACLE_HOME/rdbms/admin/catpvf.sql
