4. JDBC for DDL changes

SNMP Configuration

See SNMP Configurations in the Microsoft Windows Server Configuration section.

WMI Configuration

See WMI Configurations in the Microsoft Windows Server Configuration section.

Configuration for Database Audit Logs

Database Audit logs include failed and successful logons and other C2 audit activity. These logs are written to the Windows Application logs.

Configuration occurs in two parts.

• SQL Server Configuration

• FortiSIEM Configuration

SQL Server Configuration

Step 1: Configure Login Auditing using SQL Server Management studio

Take the following steps to configure Login Auditing.

1. In SQL Server Management Studio, connect to an instance of the SQL Server Database Engine with Object Explorer.

2. In Object Explorer, right-click the server name, and then click Properties.

3. On the Security page, under Login auditing, select the desired option

4. On the Security page, under Options, click on the Enable C2 audit tracing check box and close the Server Properties page.

5. In Object Explorer, right-click the server name, and then click Restart.
   

   

   Note: You must restart the SQL Server before this option will take effect.
   

Step 2: Enabling SQL Server Audit

Create a Server-level audit object by taking the following steps:

1. In SQL Server Management Studio, connect to an instance of the SQL Server Database Engine with Object Explorer.

2. In the Object Explorer panel on the left, expand Security.

3. Right-click Audits, and select New Audit… from the menu. This will create a new SQL Server Audit object for server-level auditing.
   

   

4. In the Create Audit window, give the audit settings a name in the Audit name field.

5. For On Audit Log Failure, select the Continue option.

6. For Audit destination, select Application Log from the drop-down list.
   

   
   

7. Click OK.

8. You will now find the new audit configuration in Object Explorer below Security > Audits. Right-click the new Audit configuration and select Enable Audit from the menu.
   

   
   

9. Click Close in the Enable Audit dialog.
   

FortiSIEM Configuration

Step1: Define the Windows Agent Monitor Template for SQL Server

Complete these steps to add a Windows Agent Monitor Template:

1. Navigate to ADMIN > Setup and click the Windows Agent tab.

2. Under Windows Agent Monitor Templates click New.

3. In the Windows Agent Monitor Template dialog box, in the Name field, enter a name.

4. Click on Event tab, and take following steps:

   1. In the Event Log row, click New.

   2. From the Type drop-down list, select Security and click Save.

   3. In the Event Log row, click New again.

   4. From the Type drop-down list, select Application.

   5. From the Source drop-down list, select SQL Server.

   6. Click Save.

      

Step 2: Associate Windows Agents to Templates

Complete these steps to associate a Host to Template:

1. Under Host To Template Associations, click New.

2. In the Host To Template Associations dialog box, enter the following information.
   

   Settings	Guidelines
   Name	Name of the Host to Template Association.
   Organization	Select the organization.
   Host	Use the drop-down list to browse the folders and select the Devices or/and Business Services to monitor and click Save.
   Template	Select one or more monitoring templates from the list, or select All Templates to include all. You can also use the serarch bar to find any specific template.
   Collector	Select the Collector from the list or select All Collectors to include all. Agents forward events to Collectors via HTTP(S). A Collector is chosen at random and if that Collector is not available or non-responive, then another Collector in the list is chosen.

3. Associate the recently added SQL Server template to SQL server host.

4. Click Save and Apply.

Step 3: Check Events via Analytics

JDBC Configuration for Database Performance Metrics

FortiSIEM can pull SQL Server performance metrics via JDBC.

Configuration occurs in two parts.

• SQL Server Configuration

• FortiSIEM Configuration

SQL Server Configuration

Step 1: Create a Read-Only User for SQL Server Monitoring

A regular Windows account cannot be used for SQL Server monitoring. FortiSIEM runs on Linux and certain Windows libraries needed for SQL Server monitoring are not available on Linux. You have to create a separate user with read-only privileges.

1. Log in to your SQL Server with sa account, and then create a read-only user to access system tables.
   

   EXEC SP_ADDLOGIN 'AOPerfLogin','ProspectHills!','master'; 
   EXEC SP_ADDROLE 'AOPerfRole';
   EXEC SP_ADDUSER 'AOPerfLogin', 'AOPerfUser', 'AOPerfRole'; 
   GRANT VIEW SERVER STATE TO AOPerfLogin;
   GRANT SELECT ON dbo.sysperfinfo TO AOPerfRole; 
   GRANT EXEC on xp_readerrorlog to AOPerfRole;
   

2. Log in with your newly created read-only account (AOPerfLogin) and run these commands.
   

   SP_WHO2 'active';
   SELECT * FROM sys.databases; SELECT * FROM dbo.sysperfinfo;
   SELECT COUNT(*) as count FROM sysprocesses GROUP BY loginame;
   

Check to see if you get the same results with your read-only account (AOPerfLogin) as you do with your sa account. You should get the same results.

Step 2: Changing Authentication mode to SQL Server and Windows Authentication Mode

It is common practice to enable SQL Server and Windows Authentication mode before accessing read-only user. To enable this mode, take the following steps:

1. In SQL Server Management Studio Object Explorer, right click the server, then click Properties.

2. On the Security page, under Sever authentication, select SQL Server and Windows Authentication mode.
   

   

3. Click OK.

4. In the SQL Server Management Studio dialog box, click OK to acknowledge the requirement to restart the SQL Server.

5. In Object Explorer, right click your server, and then click Restart. If the SQL Server Agent is running, it must also be restarted.

FortiSIEM Configuration

Settings for SQL Server JDBC Access Credentials for Performance Monitoring

Use these Access Method Definition settings to allow FortiSIEM to communicate with your SQL Server over JDBC for performance monitoring:

Step 1: Create a Separate Credential for Each Database Instance

If multiple database instances are running on the same server, then each instance must run on a separate port, and you must create a separate access credential for each instance. You must also remember to associate each instance with the server's IP number for the Device Credential Mapping Definition.

Take the following steps:

1. Go to the ADMIN > Setup > Credentials tab.

2. In Step 1: Enter Credentials, click New to create a new credential.

   1. Follow the instructions in “Setting Credentials“ in the User's Guide to create a new credential.

   2. Enter these settings in the Access Method Definition dialog box and click Save when done:
      

      1. Setting	Value
         Name	The name of the database instance you're creating the credential for.
         Access Protocol	JDBC
         Used For	Performance Monitoring
         Pull Interval (minutes)	5
         Port	1433
         Database Name	<leave this field blank>
         User Name	The user you created in step 1 of the JDBC configuration.
         Password	The password associated with the user you created in step 1.

         

3. In Step 2: Enter IP Range to Credential Associations, click New to create a new mapping.

   1. Select the name of your credential from the Credentials drop-down list.

   2. In the IP/Host Name field, enter a host name, an IP, or an IP range.

   3. Click Save.

4. Click the Test drop-down list and select Test Connectivity to test the connection to the Microsoft SQL Server.

5. To discover the device, take the following steps:

   1. Navigate to ADMIN > Setup > Discovery.

   2. Create a Discovery entry using the information here. For more information on how to create a discovery entry, see here.
      

      Setting	Value
      Name	The name of the device to discover
      Discovery Type	Leave as default (Range Scan).
      Include	Provide the IP address of the device you want discovered.

   3. Click Save when done.
      

6. Select the discovery entry you created and click Discover.

7. After Discovery is completed, navigate to ADMIN > Setup > Monitor Performance to check the monitor performance job.
   

8. Click on the More drop-down list and select Report to check related events.

   

JDBC Configuration for DDL Changes

FortiSIEM can pull SQL Server Data Definition Language (DDL) changes via JDBC. These changes include CREATE, ALTER, DROP, GRANT, DENY, REVOKE or UPDATE STATISTICS operations on database tables. This information is not naturally generated by a SQL Server. Hence, this involves creating database tables to store them and then creating triggers to populate those tables. Then FortiSIEM can pull them via JDBC.

Configuration occurs in two parts.

• SQL Server Configuration

• FortiSIEM Configuration

SQL Server Configuration

1. Save the SQL Server script (provided – link here) as separate file to My Documents > SQL Server Management Studio > SQLServer_DDL_Events.sql.

2. Login to SQL Server Management Studio with sa account.

3. Browse to and execute the SQLServer_DDL_Events.sql script to create the database, tables and trigger events.

Creating a Database Truncate Script

Since DDL tables grow after time, it is often a good idea to create a database truncate script that can run as a maintenance task and keep the table size under control. it is often necessary to create a database truncate procedure as follows.

1. Log into Microsoft SQL Management Studio and connect to the DB instance.

2. Under Management, go to Maintenance Plans, and create a new plan with the name RemoveOldLogs.

3. For Subplan, enter TRUNCATE, and for Description, enter TRUNCATE TABLE.

4. Click the Calendar icon to create a recurring, daily task starting at 12:00AM and running every 30 minutes until 11:59:59PM.

5. Go to View > Tool Box > Execute T-SQL Statement. A T-SQL box will be added to the subplan.

6. In the T-SQL box, enter this command
   

   use PH_Events;
EXEC sp_MSForEachTable 'TRUNCATE TABLE DDLEvents';

7. Click OK.

You will be able to see the history of this script's actions by right-clicking on the maintenance task, and then selecting View History.

FortiSIEM Configuration

Settings for SQL Server JDBC Access Ccredentials for DDL Events Collection

Use these Access Method Definition settings to allow FortiSIEM to communicate with your SQL Server database instance over JDBC for database DDL events collection.

Step 1: Create a Separate Credential for Each Database Instance

If multiple database instances are running on the same server, then each instance must run on a separate port, and you must create a separate access credential for each instance. You must also remember to associate each instance with the server's IP number for the Device Credential Mapping Definition.

Take the following steps:

1. Go to the ADMIN > Setup > Credentials tab.

2. In Step 1: Enter Credentials, click New to create a new credential.

   1. Follow the instructions in “Setting Credentials“ in the User's Guide to create a new credential.

   2. Enter these settings in the Access Method Definition dialog box, and click Save when done:
      

      Setting	Value
      Name	The name of the database instance you are creating the credential for
      Device Type	Microsoft SQL Server
      Used For	Audit
      Pull Interval (minutes)	5
      Port	1433
      Database Name	<leave this field blank>
      Logon Event Table	PH_Events.dbo.LogOnEvents
      DDL Event Table	PH_Events.dbo.DDLEvents
      User Name	The user you created in step 1 of the JDBC configuration
      Password	The password associated with the user you created in step 1.

      

3. In Step 2: Enter IP Range to Credential Associations, click New to create a new mapping.

   1. Select the name of your credential from the Credentials drop-down list.

   2. In the IP/Host Name field, enter a host name, an IP, or an IP range.

   3. Click Save.

4. Click the Test drop-down list and select Test Connectivity to test the connection to the Microsoft SQL Server.

5. To discover the device, take the following steps:

   1. Navigate to ADMIN > Setup > Discovery.

   2. Create a Discovery entry using the information here. For more information on how to create a discovery entry, see here.
      

      Setting	Value
      Name	The name of the device to discover
      Discovery Type	Leave as default (Range Scan).
      Include	Provide the IP address of the device you want discovered.

   3. Click Save when done.
      

6. Select the discovery entry you created and click Discover.

7. After Discovery is completed, navigate to ADMIN > Setup > Pull Events to check the pull events job.
