SQL xp_cmdshell Enabled for Remote Execution

This rule detects attempts to enable the 'xp_cmdshell' stored procedure in Microsoft SQL Server. The rule specifically looks for network traffic on port 1433 (default SQL Server port) containing the keywords 'sp_configure', 'xp_cmdshell', and '1' (indicating enablement). Enabling xp_cmdshell allows SQL Server to execute operating system commands, which is a common technique used by attackers for remote execution and persistence.
