Corporate cases usually involve server databases and it is quite difficult to deal with the active servers and perform analysis on them. It is important for investigators to know about the files belonging to SQL Server. This section will highlight the important steps while investigating SQL Server.

Retrieval of  Relevant Repositories

But it does not restrict the server information to the databases; users can retrieve it from various other files as well. Below mentioned are some of the files which have forensic importance;

  • SQL Server sessions, users, requests, and connection information.

  • Plan cache, data cache, indexes, tempdb, page file, and memory.
  • Server logs, System event logs, SQL Server trace files.

Acquiring database files can be easy by going to the mentioned paths. It must be kept into consideration that the databases need to detach or it needs to acquire by stopping the server service for a while. Once the MDF and NDF files i.e. acquire the Primary database and Secondary database, the SQL Server at the investigator’s workstation can use and analyze by creating a similar environment.

Corporates usually do not provide this much time for analyzing the databases on the servers so investigators have to make this smart move of acquiring the databases from the file system. In such a situation, the process of the operation should terminate temporarily in order to fetch all the databases. And it can complete it by executing ‘Service’ from the control panel by selecting the relevant service.
