It is highly recommended that you provide a dedicated server for the installation. When the Scan Engine is sharing an environment with other applications, you must ensure that sufficient resources are available for the duration of the scan. SQL Server should be installed on a separate server.

Software Requirements

The Scan Engine runs on a Windows Server using MS SQL Server as its data repository and IIS for its presentation layer. The Windows Server hosting the scan engine service must be configured to trust Thawte digital signatures.

SQL Server User Permissions

Installation:

  • Provide a SQL SERVER user or Active Directory account that has 'CREATE ANY DATABASE' (dbcreator) server permission.
  • The provided user will become the db_owner of the Scan Engine database (if it doesn't already exist).

    Run-Time: At run time, the user identity is remembered from the installation step
  • the user supplied at install time must have VIEW ANY DEFINITION and VIEW SERVER STATE permission.
  • if the user supplied at install time is not db_owner – user requires db_readdata and db_writedata. This scenario is only likely to occur if additional scan engine(s) are installed that share a SQL server Scan Engine database; a different SQL Server installation user could be provided to access the existing Scan Engine Database.

    Upgrade:
  • Supply a user with the db_owner role and with VIEW ANY DEFINITION and VIEW SERVER STATE permission.

IIS Default Web site must be present prior to installation.


NOTE: Although not a requirement it is strongly recommended that before an installation that a certificate and https binding be configured for the Default Web Site for the SLL flag to be set through the installation process.

Standard SQL Server Configuration

The Scan Engine database components are installed into a Microsoft SQL server instance. The installation of SQL Server database should follow the installation instructions supplied by Microsoft.
The following configuration changes are required:

  1. The database user account that is used for installing the scan engine should have elevated privileges (with the ability to create a new database).
  • Installation requires a database user that has dbcreate permissions.
  • If the database does not exist, creating the DB will mark the selected user as a member of dbowner.
  • For the scan engine, the database user that is selected during the installation process will continue to be used as the Application login identity for the database. The selection of the 'SA' account is, therefore, not recommended.
  1. The database logging should be configured to simple by default.
  2. It is recommended that the database growth interval be changed to 256MB (for Database and Logs).
  3. The .NET CLR option in SQL Server must be enabled for the scan engine to function correctly:

    sp_configure @configname=clr_enabled, @configvalue=1GORECONFIGURE GO

    NOTE: It is recommended that SQL Server Profiler option is enabled as part of the SQL Server installation; it is a useful troubleshooting tool.
