oracle之监听保护

oracle之监听保护

 

今天是2013-08-24，不对刚刚过了12点，应该是2013-08-25日，今天我的同事对数据库 进行监听安全加固失败，然后 我的哥们也做了同样的实验，结果还是失败，至此我不知道 什么原因，在此想对显伟兄说一句，对此我感到很抱歉，我没有拿出时间来和你研究这个问题的错误，希望得到大家的谅解。写这篇日志，就是为了展示我怎么做的。希望对 大家有帮助。也欢迎高手提出见解和宝贵的意见，小海我坦然耐心虚心接受,我知道不懂的虚心去学习的人，终究会失去成功的机遇。好了。在此记录一下笔记：

 

其实我一直不赞同设置监听保护，但是可能是为了完成安全扫描的要求才进行整改的。它的安全扫描就一定正确吗？对于我来说只有经历过真正实验过才知道答案，不能胡说八道。

notice：

Ensure that the password has not been set in the listener.ora file. The local operating system authentication will secure the listener administration. The remote listener administration is disabled when the password has not been set. This prevents brute force attacks of the listener password.

 

Remember that the listener password has been deprecated in this release, and will not be supported in the next release of Oracle Database

 

好，步骤如下：

[oracle@oracle-one admin]$ lsnrctl start

ok，看到我们现在的security 为：Local OS Authentication，然后设置password，如下：

 

[oracle@oracle-one admin]$ lsnrctl
