6.3 Ensure 'log_error_verbosity' is Set to '2'


The log_error_verbosity system variable, set to 2 by default, specifies the verbosity of events sent to the MySQL error log. A value of 2 enables logging of error and warning messages, a value of 3 also includes informational logging, a value of 1 logs only errors.


This might help to detect malicious behavior by logging communication errors and aborted connections.


Perform the following actions to remediate this setting:

Open the MySQL configuration file (my.cnf)

Ensure the following line is found in the mysqld section

log_error_verbosity = 2

Default Value:

The option is enabled (3) - errors, warning, and information messages are logged - by default.
