Para buscar elementos asociados con certificados y claves asimétricas, primero intente la consulta publicada en este DBA. Respuesta de SE:
Encuentre procedimientos firmados, funciones, disparadores, ensamblajes y por qué certificados / claves asimétricas
Si eso no devuelve ningún objeto, intente las siguientes consultas que buscan:
- Logins
- Los usuarios
- Puntos finales de Service Broker
- Puntos finales de creación de reflejo de la base de datos
- Llaves simétricas
- Claves de cifrado de bases de datos (utilizadas para TDE)
Tenga en cuenta que los inicios de sesión son a nivel de servidor / instancia mientras que todo lo demás es a nivel de base de datos. Además, las claves de cifrado de la base de datos, aunque se encuentran en el nivel de la base de datos, se informan en un DMV que devuelve datos para todas las bases de datos y, por lo tanto, no cambia en función de la base de datos "actual".
