As an enterprise-class relational database system, SQL Server provides a comprehensive and powerful set of features, such as high availability, scalability, and performance. In order to ensure the normal operation of SQL Server, a corresponding communication port needs to be configured on the server. So how to use the SQL Server port correctly? This article will explain the relevant attention points of the segment.
First of all, SQL Server runs on the default port 1433, but if the server is where multiple network services are running, it is necessary to change the default port to prevent conflict conflict of SQL Server services, also can effectively reduce the risk of being attacked by hackers. Of course, to change the port, it is necessary to enter the connection information of the client to configure the port information before the server is connected. Usually we can enter the following command to configure the port：
exec sp_configure ‘show advanced options’, 1
GO
RECONFIGURE
GO
exec sp_configure ‘user connections’, 200
GO
RECONFIGURE
–Set port
exec sp_configure ‘Central Management Server port’, {指定的端口}
Go
RECONFIGURE
GO
In addition, in general SQL Server settings, the “remote access” option is set to disallow unauthorized by default. This can prevent malicious destruction in some cases. However, for remote connections, you will need to enable this option to allow remote connections. In this case, it is recommended to use a secure server address and set a strong password as much as possible to protect account security. In addition, it is also necessary to close unnecessary ports on the server to prevent hackers from using these potential port threats to attack our servers.
Finally, it is suggested to enable and manage the firewall of the server. This can effectively protect the data from being attacked or leaked by malicious personnel. Meanwhile, you can also enable the browser service to track server wide activities, in order to quickly detect malicious actions.
In a word, the correct use of SQL Server ports plays an important role in security protection. For database administrators and IT personnel to do a good job of managing and protecting, only correct and correct setting of SQL Server ports can ensure that users can better use server-side database services and protect the safe operation of the server.
