 description: This detection helps hunt for changes to SQL Server configuration options that could indicate malicious activity. It monitors for modifications to any SQL Server configuration settings, allowing analysts to identify potentially suspicious changes that may be part of an attack, such as enabling dangerous features or modifying security-relevant settings.

 description: This detection identifies when critical SQL Server configuration options are modified, including "Ad Hoc Distributed Queries", "external scripts enabled", "Ole Automation Procedures", "clr enabled", and "clr strict security". These features can be abused by attackers for various malicious purposes - Ad Hoc Distributed Queries enables Active Directory reconnaissance through ADSI provider, external scripts and Ole Automation allow execution of arbitrary code, and CLR features can be used to run custom assemblies. Enabling these features could indicate attempts to gain code execution or perform reconnaissance through SQL Server.
