When using command-line tools such as db2, users must use a Connect method that does not expose the password.
Description
Discussion Text
To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information that would allow an unauthorized user to compromise the authentication mechanism.
Obfuscation of user-provided information when typed into the system is a method used in addressing this risk.
For example, displaying asterisks when a user types in a password or PIN, is an example of obscuring feedback of authentication information.
"db2" and other command-line tools are part of any DB2 for LUW installation. These tools can accept a plain-text password, but do offer alternative techniques. Since the typical user of these tools is a database administrator, the consequences of password compromise are particularly serious. Therefore, the use of plain-text passwords must be prohibited, as a matter of practice and procedure.
