本文介绍了如何使用SEC_PROTOCOL_ERROR_FURTHER_ACTION初始化参数来控制服务器进程接收到恶意客户端发送的坏数据包后的处理方式。设置为Drop,10时，会在接收到10个坏数据包后终止客户端连接，但允许客户端重新连接并再次尝试相同的操作。

QUESTION 51
To control the execution of a server process when it is receiving bad packets from a potentially
malicious client, you set the SEC_PROTOCOL_ERROR_FURTHER_ACTION initialization parameter as
follows:
SQL> ALTER SYSTEM SET SEC_PROTOCOL_ERROR_FURTHER_ACTION = Drop,10;
What is the significance of this setting?
A. It terminates the client connection after 10 bad packets and the client cannot reconnect to the same
instance.
B. It terminates the client connection after 10 bad packets but the client can still reconnect, and attempt
the same operation again.
C. It terminates the client connection 10 seconds after receiving a bad packet and the client cannot
reconnect to the same instance.
D. It terminates the client connection after receiving a bad packet and the client can reconnect to the
same instance after 10 minutes.
Correct Answer: B

要控制一个服务器进程的执行，当它接收来自一个潜在的坏数据包时
恶意的客户端，
你sec_protocol_error_further_action初始化参数设置
如下
SQL> ALTER SYSTEM SET SEC_PROTOCOL_ERROR_FURTHER_ACTION = Drop,10;
这个设置的意义是什么？

B.它终止了客户端连接后，10个坏数据包，但客户端仍然可以重新连接，并尝试
同样的操作。
