GBase 8a 对明文密码的安全保护措施

本文介绍在GBase 8a 数据库集群里,在涉及密码明文的安全保护方面处理措施,确保密码明文不会被获得。包括命令行登录密码,SQL语句里连接数据源的密码,同时在数据库日志里也需要屏蔽。

命令行工具gccli进程登录密码

登录数据库输入了密码。

[gbase@gbase_rh7_001 ~]$ gccli -ugbase -pgbase20110531 -e"select sleep(100)"
+------------+
| sleep(100) |
+------------+
|          0 |
+------------+
[gbase@gbase_rh7_001 ~]$

ps查看进程信息没有明文

Last login: Mon Mar 29 13:58:31 2021 from 192.168.56.1
[root@gbase_rh7_001 ~]#
[root@gbase_rh7_001 ~]# ps -ef|grep gccli
gbase     4546  3381  0 14:19 pts/0    00:00:00 gccli -ugbase -pxxxxxxxxxxxxx -eselect sleep(100)
root      4900  4726  0 14:19 pts/1    00:00:00 grep --color=auto gccli
[root@gbase_rh7_001 ~]#

SQL语句包含数据源密码

[gbase@gbase_rh7_001 ~]$ gccli -ugbase -pgbase20110531 -e"load data infile 'sftp://gbase:gbase1234@10.0.2.202/home/1/txt' into table vc1.testdb.t1 "

查看进程 show processlist,没有发现明文
