When a command is executed on the command line, for example mysql -u admin - ppassword, the password may be visible in the user's shell/command history or in the process list. NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Use -p without password and then enter the password when prompted, use a properly secured .my.cnf file, or store authentication information in encrypted format in .mylogin.cnf.
