Microsoft-SQL-Monitor
MS-SQL-M is a service associated with Microsoft SQL Server, which uses port 1434 for communication. This service is essential for database management tasks, including querying, updating, and managing databases. It facilitates the interaction between SQL Server instances and client applications.
What is Microsoft-SQL-Monitor
MS-SQL-M, or Microsoft SQL Server Monitor, is a service that operates on port 1434. It is primarily used for database management and communication tasks within Microsoft SQL Server environments. This service plays a crucial role in enabling SQL Server instances to communicate with client applications, allowing for efficient querying, updating, and management of databases.
Microsoft SQL Server is a relational database management system developed by Microsoft. It is widely used in enterprise environments for storing and retrieving data as requested by other software applications. The MS-SQL-M service helps in the discovery of SQL Server instances on a network, making it easier for client applications to connect to the appropriate database server.
The history of Microsoft SQL Server dates back to the late 1980s, and it has since evolved into a robust and feature-rich database management system. The MS-SQL-M service is an integral part of this system, ensuring seamless communication and management of databases. Organizations rely on this service to maintain the integrity and performance of their SQL Server environments.
Microsoft-SQL-Monitor runs on TCP and UDP port 1434 and is official IANA port.Security risk
If port 1434 is open and the MS-SQL-M service is running, it can expose the SQL Server to potential security risks, including unauthorized access and data breaches. Attackers could exploit vulnerabilities in the service to gain access to sensitive data or disrupt database operations. It is crucial to secure this port and implement proper authentication and encryption measures to mitigate these risks.
In our UFW tutorial you can follow instructions how you can configure UFW to close port 1434. Use StackChanges to monitor if the Microsoft-SQL-Monitor port is closed and stays closed. StackChanges will send an alert if port 1434 is open again.
