You can either enable or disable the sensitive log and trace guard to help control whether loggers write sensitive information in your log and trace files.
Administrators using WebSphere® Application Server can prevent sensitive information, such as data provided from users in HTTP requests, from being written in log and trace files. In some cases, when having access to private data can help with debugging, you might want to disable sensitive log and trace guard. For example, you might see that a credit card number that was entered in a web form did not have the required number of digits.
Sensitive log and trace guard works by preventing administrators from enabling certain loggers to levels at which they are known to log or trace sensitive information.
Use the administrative console to enable or disable the sensitive log and trace guard.
