@Biswas, Sauvik
Thank you for the question and for using Microsoft Q&A platform.
VA2107 is a rule from the SQL Vulnerability Assessment tool, which focuses on ensuring that the minimal set of principals are members of fixed high-impact database roles. This rule helps to reduce the risk of excessive permissions being granted to users, which could potentially be exploited by attackers.
Key Points of VA2107:
Objective: Ensure that only necessary principals have membership in high-impact roles to minimize security risks.
High-Impact Roles: These typically include roles like db_owner, db_securityadmin, and other roles that have significant control over the database.
Remediation: Review the members of these roles and remove any principals that do not require such high levels of access. The script you mentioned, ALTER ROLE [UserRole] DROP MEMBER [Principal], is used to remove a member from a role, which is a common remediation step for this rule.
