MSSQL

Microsoft SQL Server is a relational database management system that operates by default on port 1433, used for managing and querying structured data in enterprise environments.

MSSQL enables secure and efficient database operations, supporting Transact-SQL for querying and database management. It provides features like data storage, high availability, backup and recovery, and authentication mechanisms.

Its main features are:

  • Allows TLS/SSL encryption for secure database connections

  • Role-based Access Control for specifying user permissions

  • Set firewall rules to control external access to the SQL server

  • Tracks database access and query execution for security monitoring

To interact with the service, we can use tools such as the mssqlclient utility, which is part of the Impacket toolkit.

Interaction and Query Syntax

  • MSSQL uses standard SQL with a few variants for some commands

SELECT name FROM sys.databases; #Show databases
SELECT name FROM sys.tables; #Show tables
USE $databaseName; #Select a database
SELECT * FROM table $tableName; #Get all the information from a table
