Oracle监听口令及监听器安全

来源:网络摘录日期:2008-09-16 05:14 点击:0

很多人都知道，Oracle的监听器一直存在着一个安全隐患，假如不设置安全措施，那么能够访问的用户就可以远程关闭监听器。

相关示例：

         D:\>lsnrctl stop eygle
        LSNRCTL for 32-bit Windows: Version 10.2.0.3.0 - Production on 28-11月-2007 10:02:40
        Copyright (c) 1991, 2006, Oracle. All rights reserved.

正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.33.11)(PORT=1521))

(CONNECT_DATA=(SERVICE_NAME=eygle)))

命令执行成功

大家可以发现，此时缺省的监听器的日志还无法记录操作地址：

         No longer listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=172.16.33.11)(PORT=1521)))
        28-NOV-2007 09:59:20 * (CONNECT_DATA=(CID=(PROGRAM=)(HOST=)(USER=Administrator))(COMMAND=stop)
        (ARGUMENTS=64)(SERVICE=eygle)(VERSION=169870080)) * stop * 0

为了更好的保证监听器的安全，大家最好为监听设置密码：

         [oracle@jumper log]$ lsnrctl
        LSNRCTL for Linux: Version 9.2.0.4.0 - Production on 28-NOV-2007 10:18:17
        Copyright (c) 1991, 2002, Oracle Corporation. All rights reserved.

        Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.33.11)(PORT=1521)))
        Password changed for listener
