+If the protocol address contains the user name and password, the ps -ef
+command exposes plaintext. The -mask_url parameter option is added to
+replace the protocol address in the command line with the asterisk (*).
+Because other users can run the ps -ef command to view sensitive
+information such as the user name and password in the protocol address,
+which is insecure.
